10 Best Appointment Reminder Software in 2026, Compared

Quick comparison

The best appointment reminder software

#1

Apptoto

Best for: Service businesses that want a dedicated reminder tool layered over the calendar they already use

★★★★★★★★★★4.8/5 on Capterra (94 reviews, checked Nov 2026)

Visit apptoto.com

Starting price$39/month (Starter, 3 calendars; annual billing discounted)

Free planNo — 14-day free trial

Apptoto is the only tool in this list built purely around reminders, and that focus shows. It connects to the calendar a practice already uses, reads the appointments, finds the client contact details and sends SMS, email or voice reminders before each visit, then follows up afterwards. Clients can confirm, cancel or reschedule by reply, and staff can message them back in a two-way conversation.

Starter costs $39 a month and covers 3 calendars, 3 users and 450 automated message credits a month, with unlimited manual messages and online booking pages. That allowance covers a practice sending one reminder per appointment for about 300 appointments a month, but two reminders per appointment needs the $78 Plus plan. Buy Apptoto when reminders are the job and the booking system already works.

What we like

• Built only for reminders: SMS, email and voice reminders with two-way replies, confirmations and follow-ups
• Connects to Google Calendar, Outlook and other calendars, so no rebooking or migration is needed
• Starter includes 3 calendars, 3 users, unlimited manual messages and 450 automated message credits a month

Watch out for

• No free plan, only a 14-day trial, and $39/month is the highest entry price among the dedicated reminder tools here
• Pricing scales by calendars and message credits, so a busy practice can outgrow the 450-credit Starter allowance
• It layers reminders over an existing calendar rather than replacing a full booking system

#2

Appointment Reminder

Best for: Clinics and solo practices that want every reminder channel on one flat plan priced by volume

Visit appointmentreminder.com

Starting price$29/month (Starter, 400 reminders/month; 1 month free on annual billing)

Free planNo — 14-day free trial

Appointment Reminder does one job with unusual pricing clarity: every plan includes the same features, and only the reminder allowance changes. Starter costs $29 a month for 400 reminders and includes SMS, email and voice reminders, two-way messaging, automated workflows, custom templates, an online booking page and unlimited calendars and team members. Emails are free and unlimited, so only texts and calls count against the allowance.

The flat structure is the appeal and the limit. A solo practice sending 300 reminders a month fits Starter comfortably, but a practice sending 500 needs Growth at $49 a month for 800 reminders. Annual billing gives one month free. Buy it when the practice wants every channel included and a bill that rises only with volume, not with staff.

What we like

• Every plan includes SMS, email and voice reminders, two-way messaging, workflows and an online booking page
• Pricing is by reminder volume only: Starter covers 400 reminders a month for $29, with unlimited calendars and team members
• Annual billing gives 1 month free, and emails are free and unlimited on every plan

Watch out for

• Every plan costs the same per reminder allowance, so a practice sending few reminders pays the same as a busier one on the same tier
• The vendor's own FAQ says the signed HIPAA BAA sits on the Pro plan and above, not on Starter
• No public review score we could verify today, so there is no independent rating to lean on

#3

GoReminders

Best for: Solo providers who want the cheapest dedicated SMS and email reminder tool

★★★★★★★★★★4.6/5 on G2 (697 reviews, checked Nov 2026)

Visit goreminders.com

Starting price$8/month (Solo; vendor-supplied via G2 — some directories list $9/month)

Free planNo — 14-day free trial

GoReminders is the cheapest dedicated reminder tool here, and it keeps the job simple: automated SMS and email reminders, confirmations and calendar integration, with online booking included. There is no booking website to build and no payments module to learn. A solo provider connects a calendar, sets the reminder timing and lets the tool chase confirmations.

Solo costs $8 a month on vendor-supplied G2 pricing, although several directories list $9 a month, so confirm the figure at checkout. The trade-off is scope: two-way messaging and richer features cost extra or sit on higher tiers, and GoReminders is a reminder add-on rather than a full scheduler. Buy it when the calendar already works and only the reminders need automating.

What we like

• Cheapest dedicated reminder tool here at $8/month for the Solo plan
• Sends automated SMS and email reminders with confirmations and calendar integration
• Highest review volume among the dedicated reminder tools here, at 4.6 out of 5 on G2 across 697 reviews

Watch out for

• Vendor-supplied G2 pricing lists Solo at $8/month while several directories list $9/month, so confirm the figure at checkout
• Two-way messaging and some features cost extra or sit on higher tiers
• No booking website or payments on the entry plan; it is a reminder add-on, not a full scheduler

#4

Setmore

Best for: Small teams that want a real free plan and will pay only when they need text reminders

★★★★★★★★★★4.5/5 on G2 (269 reviews, checked Nov 2026)

Visit setmore.com

Starting price$12/user/month (Pro, billed monthly; $5/user/month billed annually)

Free planYes — Free plan (up to 4 users)

Setmore has the most generous free plan in this list: up to 4 users, unlimited appointments, online payments and email reminders at $0. That makes it the only tool here a small team can run properly without paying anything. Pro adds the features that cut no-shows, including automated SMS reminders, two-way calendar sync, recurring appointments, deposits and API access, for $12 a user a month, or $5 a user a month billed annually.

The annual price is the one to budget on: a 3-person team pays $15 a month billed annually against $36 month to month. Pro also includes 500 SMS credits a month per team member. The weak spot is calendar sync, which reviewers report as unreliable at times. Buy Setmore when the team is small, the budget is tight and text reminders are the missing piece.

What we like

• The most generous free plan here: up to 4 users, unlimited appointments and email reminders at $0
• Pro drops to $5/user/month on annual billing, the cheapest paid per-user price in this list
• Pro adds SMS reminders, two-way calendar sync, recurring appointments and deposits

Watch out for

• Automated SMS reminders need Pro; the free plan sends email reminders only
• Two-way calendar sync and deposits sit on Pro, so the free plan is one-way only
• Reviewers report Google Calendar sync can be unreliable, which matters when reminders depend on it

#5

Calendly

Best for: Professionals and sales teams who book one-to-one meetings and want reminders attached to each booking

★★★★★★★★★★4.7/5 on G2 (2,643 reviews, checked Nov 2026)

Visit calendly.com

Starting price$12/seat/month (Standard, billed monthly; $10/seat/month billed annually)

Free planYes — Free plan (1 event type)

Calendly is the meeting-scheduling standard, and reminders ride along with the booking link. A client picks a time, Calendly checks the connected calendars, and Standard adds automated email and text reminders through Workflows, plus payment collection through Stripe or PayPal. It is the smoothest option here for one-to-one meetings, sales calls and consultations.

Standard costs $12 a seat a month, or $10 billed annually, and unlocks unlimited event types and up to 6 connected calendars. The free plan allows only one event type, so anyone offering more than one meeting type must pay, and round-robin scheduling needs Teams at $16 a seat a month billed annually. Buy Calendly when the work is meetings, not service appointments with rooms and staff.

What we like

• Highest G2 score in this list at 4.7 out of 5, across more than 2,600 reviews
• Standard unlocks unlimited event types, up to 6 connected calendars and automated email and text reminders
• Stripe and PayPal payment collection starts on Standard, so clients can pay when they book

Watch out for

• The free plan allows only 1 event type, so anyone offering more than one meeting type must pay
• Text reminders run through Workflows on Standard and above; the free plan covers email only
• Round-robin and routing forms need Teams at $16/seat/month billed annually

#6

SimplyBook.me

Best for: Service businesses that want to pay by monthly bookings, not by staff seats

★★★★★★★★★★4.4/5 on G2 (110 reviews, checked Nov 2026)

Visit simplybook.me

Starting price€13.90/month (Basic, billed monthly; €11.90/month billed annually)

Free planYes — Free plan (1 provider, 50 bookings/month)

SimplyBook.me charges by bookings, not by seats, which changes the maths for teams. Basic costs €13.90 a month, or €11.90 billed annually, and covers 5 providers, 100 bookings a month and 3 custom features, with email and SMS reminders included on every tier. A five-person team pays the same as a solo provider, and the free plan covers 1 provider and 50 bookings a month.

The booking cap is the limit to watch: an active business passes 100 bookings a month quickly and then needs Standard at €29.90 a month for 500 bookings. Prices are in euros, so US buyers pay the converted amount, and HIPAA compliance starts on Standard. Buy SimplyBook.me when the team is bigger than the booking volume.

What we like

• Charges by bookings, not seats: Basic covers 5 providers for €13.90/month, so adding staff costs nothing extra
• Email and SMS reminders are core features on every tier, including the free plan
• Free plan needs no credit card, and paid plans include a booking website and client app

Watch out for

• Priced in euros, so US buyers pay the converted amount and the dollar figure moves with the exchange rate
• Basic caps at 100 bookings a month with only 3 custom features, so active businesses outgrow it fast
• HIPAA compliance starts on Standard at €24.90/month billed annually, not on Basic

#7

Acuity Scheduling

Best for: Solo practitioners and small teams that take payment at booking and want polished intake forms

★★★★★★★★★★4.6/5 on G2 (410 reviews, checked Nov 2026)

Visit acuityscheduling.com

Starting price$20/month (Starter, billed monthly; $16/month billed annually)

Free planNo — 7-day free trial

Acuity Scheduling, owned by Squarespace, is built for businesses where the appointment is the product: coaches, therapists, tutors and practitioners who take payment at booking. Starter costs $20 a month, or $16 billed annually, for one calendar, and includes email reminders, intake forms, deposits and payments through Stripe, Square, PayPal or Venmo.

The catch is that text reminders are not on Starter; they start on Standard at $27 a month billed annually, which covers up to 6 calendars. There is no free plan, only a 7-day trial. Buy Acuity when clients pay at booking and intake forms matter, and budget for Standard if text reminders are the point of buying.

What we like

• Email reminders, intake forms, deposits and payments through Stripe, Square, PayPal or Venmo on every plan
• Flat pricing by calendar, not per seat: Starter covers 1 calendar for $20/month
• Standard adds text reminders, packages, memberships, gift certificates and a waitlist

Watch out for

• Text reminders are not on Starter; they start on Standard at $27/month billed annually
• No free plan, only a 7-day trial, and pricing climbs by calendar count as staff are added
• Third-party sources disagree on the Premium tier ($49 or $55 a month billed annually), so confirm it before budgeting for HIPAA

#8

Appointy

Best for: Salons, clinics and fitness studios that want reminders included on a free plan

★★★★★★★★★★4.5/5 on G2 (23 reviews, checked Nov 2026)

Visit appointy.com

Starting price$29.99/month (Growth, billed monthly; $19.99/month billed annually)

Free planYes — Free plan (1 staff, 100 appointments/month)

Appointy is the budget pick for salons, clinics and fitness studios because automated reminders are included on its free plan, which covers 1 staff member and 100 appointments a month. Growth costs $29.99 a month, or $19.99 billed annually, and adds unlimited services, two-way calendar sync and payment collection, with packages, memberships and gift cards across the plans.

The limits sit in the fine print: extra staff cost extra on top of Growth, and removing Appointy branding needs Enterprise at $79.99 a month billed annually. Its G2 base is also the smallest here, at 23 reviews. Buy Appointy when the business is small, reminders matter most and the free plan covers the current volume.

What we like

• Automated reminders are included on the free plan, which covers 100 appointments a month for 1 staff member
• Growth adds unlimited services, two-way calendar sync and payment collection for $19.99/month billed annually
• Covers salons, clinics, fitness studios and consultants with packages, memberships and gift cards

Watch out for

• Two-way calendar sync and payment collection need Growth at $19.99/month billed annually
• Removing Appointy branding needs Enterprise at $79.99/month billed annually
• Smallest G2 review base in this list at 23 reviews, so the 4.5 score carries less weight

#9

Zoho Bookings

Best for: Small teams already running on Zoho who want reminders inside the Zoho suite

★★★★★★★★★★4.1/5 on G2 (54 reviews, checked Nov 2026)

Visit zoho.com

Starting price$8/user/month (Basic, billed monthly; $6/user/month billed annually)

Free planYes — Free plan (1 user)

Zoho Bookings is the cheapest way into a full scheduler here, and the natural pick inside the Zoho suite. Basic costs $8 a user a month, or $6 billed annually, and includes unlimited event types, online meetings, notification emails and reminders, and two-way sync with Zoho, Google and Microsoft 365 calendars. It is also included in Zoho One, so existing subscribers may already have it.

The free plan covers only one team member, so every extra person adds $6 to $9 a month, and payment collection needs Premium at $9 a user a month billed annually. It also carries the lowest G2 score here, 4.1 out of 5 across 54 reviews. Buy Zoho Bookings when the business already runs on Zoho and reminders need to live inside that suite.

What we like

• Cheapest paid entry among the full schedulers here: Basic is $6/user/month billed annually
• Free plan includes online meetings, notification emails and reminders, and two-way calendar sync
• Included in Zoho One, so Zoho subscribers may already have it at no extra cost

Watch out for

• The free plan covers only 1 team member, so every extra person adds $6 to $9 a month
• Payment collection needs Premium at $9/user/month billed annually
• Lowest G2 score in this list at 4.1 out of 5, across only 54 reviews

#10

Square Appointments

Best for: Businesses that already take card payments through Square and want booking inside the same system

Visit squareup.com

Starting priceFree (Free plan; Plus $49/month per location)

Free planYes — Free plan ($0, 1 location, unlimited staff calendars)

Square Appointments is the only genuinely free plan in this list for a business that already takes cards through Square: $0 for one location, with a booking website, unlimited staff calendars, text and email reminders, deposits, prepayments and invoices. Booking, payments and POS live in one Square account, so there is no separate processor to set up and no per-user charge as staff join.

The free plan's gaps are the tools that protect revenue: no-show fees, the waitlist, classes and Google Calendar sync all need Plus at $49 a month per location, and Premium at $149 adds resource management. Card processing runs 2.6% plus $0.15 in person on Free. Start on Square when the business already runs on it.

What we like

• A genuinely free plan with unlimited staff calendars and no monthly subscription fee
• Text and email reminders are included on every plan, including Free
• Booking, payments and POS live in one Square account, so no separate processor is needed

Watch out for

• No-show fees, the waitlist and classes all need Plus at $49/month per location
• Paid plans are priced per location, so a second site doubles the subscription
• No public review score we could verify today, so there is no independent rating to lean on

The best appointment reminder software cuts no-shows without adding admin: clients get a text, email or voice reminder, confirm or reschedule in one tap, and the calendar stays full. We ranked the ten tools below by fit for the most common buyer — a small service business or clinic that books appointments all day — starting with the dedicated reminder specialists and ending with the full schedulers, and every price was checked on the vendor's own pricing page on November 10, 2026.

How to choose the best appointment reminder software

• Count reminders, not just appointments. Apptoto Starter covers 450 message credits a month and Appointment Reminder Starter covers 400 reminders. One reminder per appointment fits; two reminders per appointment doubles the count.
• Check which channels the plan you would buy includes. Text reminders sit on a paid tier for Acuity Starter and Setmore Free, while the dedicated tools include SMS, email and voice from the start.
• Work out the pricing unit first. Apptoto and Appointment Reminder charge per reminder, Acuity per calendar, Calendly and Setmore per user, and SimplyBook.me per booking. The unit decides the real bill.
• Decide whether you need a reminder layer or a full scheduler. Apptoto, Appointment Reminder and GoReminders sit on top of the calendar you already use; Calendly, Acuity, Setmore and the rest replace the booking system.
• Check the HIPAA question if you handle patient data. A signed agreement is a tier feature, not a given: Appointment Reminder puts it on Pro and above, and SimplyBook.me starts it on Standard.
• Send yourself a test reminder before you pay. Book an appointment, wait for the reminder, confirm it and reschedule it. If that loop feels clumsy, clients will feel it too.

Clinics have extra compliance and intake needs on top of reminders, so our guide to medical appointment scheduling software covers the healthcare side in full. Before you publish new service pages for the bookings you win back, run your titles through the free SERP snippet preview tool — it shows exactly how the title and description will look in Google.

Whatever you shortlist, try it with real appointments before you pay. The trials in this list run 7 to 15 days, which is long enough to run one genuine week — your services, your staff, your clients — and that week tells you more than any review can. Check two things in the trial: that reminders arrive on time, and that a client can confirm or reschedule by reply without calling you.

Appointment reminder software pricing: what you will actually pay

Take a solo provider at one location sending about 300 reminders a month, one per appointment. On list prices, the subscription costs $0 a month on Square Appointments Free and Setmore Free, $8 on GoReminders Solo and Zoho Bookings Basic, $12 on Calendly Standard and Setmore Pro, $20 on Acuity Scheduling Starter, $29 on Appointment Reminder Starter, $29.99 on Appointy Growth and $39 on Apptoto Starter. SimplyBook.me Basic costs €13.90 a month in euros.

Over a year on annual billing, that is $0 on Square Free and Setmore Free, $60 on Setmore Pro, $72 on Zoho Bookings Basic, $96 on GoReminders Solo, $120 on Calendly Standard, €142.80 on SimplyBook.me Basic, $192 on Acuity Scheduling Starter, $239.88 on Appointy Growth and $319 on Appointment Reminder Starter, which gives one month free. Apptoto publishes an annual discount but no annual figure we could quote, so its year costs $468 on monthly billing. The same solo provider and the same 300 reminders cost $0 at the cheap end and $468 at the dear end — a $468 gap that comes entirely from the pricing unit, not from features.

Send two reminders per appointment and the maths changes. Six hundred messages a month breaks Apptoto Starter at 450 credits and Appointment Reminder Starter at 400 reminders, so the provider needs Apptoto Plus at $78 a month or Appointment Reminder Growth at $49 a month for 800 reminders. Setmore Pro, Calendly Standard and the other schedulers charge by user or calendar instead, so a second reminder costs nothing extra. If the business also takes payments at booking, compare the payment side too — see our guide to salon booking software for the paid-appointment side.

Three costs sit outside every number above. First, message overages: the dedicated tools charge by the reminder, so count repeats and follow-ups, not just appointments. Second, card processing on the schedulers that take payments, which runs about 2.6% plus $0.15 in person on Square Free. Third, the tier gates: text reminders on Acuity and HIPAA compliance on SimplyBook.me both need a higher plan than the entry one. Annual billing cuts the bill on most tools here: Calendly Standard drops from $144 to $120 a year, and Acuity Starter from $240 to $192.

Know the difference: a reminder tool vs a full booking system

The confusion in this category is between a tool that sends reminders and a tool that takes bookings. A reminder tool — Apptoto, Appointment Reminder and GoReminders — connects to the calendar you already use, reads the appointments and sends the reminders. It does not replace the booking page, the payments or the client records. A full booking system — Calendly, Acuity, Setmore, SimplyBook.me, Appointy, Zoho Bookings and Square Appointments — does the whole job: clients book, pay, get reminded and reschedule inside one product.

The practical question is what already works. If the calendar and booking flow already work and only no-shows hurt, a reminder layer is cheaper and faster to set up: GoReminders at $8 a month or Appointment Reminder at $29 can sit on top of Google Calendar today. If bookings still arrive by phone and email, a scheduler fixes the whole workflow, and the reminders come with it — Setmore Free and Square Free both include them at $0.

There is a second, quieter confusion: email reminders and text reminders are not the same purchase. Email reminders are included on nearly every plan here, including the free ones. Text reminders, the ones clients actually read and reply to, sit on a paid tier for Acuity Starter and Setmore Free. Always check which channel the plan you would buy includes, not just whether the tool "sends reminders".

Quick comparison: tool type by need

Mistakes to avoid

• Budgeting on the headline price alone. A $29 tool can cost $49 a month once reminder volume is counted, and a $12 per-user tool can cost $36 for three people. Price the tool for your actual reminder count and headcount.
• Assuming text reminders are included. Acuity Starter and Setmore Free send email reminders only. If texts are the reason you are buying, check the tier that includes them before you compare prices.
• Buying a full scheduler when only reminders are missing. A reminder layer at $8 to $39 a month fixes no-shows without migrating bookings, payments and client records to a new system.
• Forgetting the message allowance. Apptoto Starter covers 450 credits and Appointment Reminder Starter covers 400 reminders. Two reminders per appointment plus a follow-up breaks both allowances at 300 appointments a month.
• Ignoring the HIPAA tier. Clinics need a signed agreement, and it sits on a higher plan: Pro and above on Appointment Reminder, Standard and above on SimplyBook.me. Budget for that tier from the start.

How we chose

We checked each vendor's own pricing page on November 10, 2026 and recorded the starting price exactly as shown, including the annual-billing figure where the page lists one, and we ranked the tools by fit for the most common buyer — a small service business or clinic that books appointments all day — not by brand size. One price is not vendor-verified: GoReminders lists Solo at $8/month on vendor-supplied G2 pricing, while several directories list $9/month, so we lead with $8 and flag the conflict. SimplyBook.me is priced in euros, so it is excluded from the dollar chart. Ratings are shown only where a fresh G2 or Capterra page gave a clear score and review count on November 10, 2026: Apptoto, GoReminders, Setmore, Calendly, SimplyBook.me, Acuity Scheduling, Appointy and Zoho Bookings. Square Appointments and Appointment Reminder carry no rating here because no G2 or Capterra page we opened gave a verified score and count. Third-party sources disagree on Acuity's Premium tier ($49 or $55 a month billed annually), so we do not quote it. No vendor paid for a place in this list, and none of the links here are affiliate links.

What to do next

Start with the free plan or trial of your top pick and run one real week of appointments through it. Count the reminders you actually send, including repeats and follow-ups, and check that clients can confirm or reschedule by reply without calling. If the reminders arrive on time and the no-show slots shrink, you have your tool. If the bookings are sorted but new customers are not finding you, our local SEO service handles the visibility side. Once your tools are in place, find out what's holding your rankings back.
