12 Best Cross-Platform Calendar for 2026 (Pros, Cons and Pricing)

Google Calendar is the default answer for a reason: it costs nothing, runs on every device you own, and shows the same events on your phone, your computer and the web within seconds of a change. Shared calendars, booking pages and room booking are all included free, and because nearly every calendar app connects to Google, it also works as the base layer underneath a paid planner such as Morgen or Reclaim.

What it does not do is plan the day for you. There is no time-blocking, no focus-time defence and no AI that moves tasks when a meeting runs over, so people who want the calendar to organise their work still need a second tool. If your life already runs on Gmail and Google accounts, start here and spend nothing — most people never need to leave.

Outlook Calendar is the free calendar for the Microsoft half of the world. Any Outlook.com account gets a full calendar on iOS, Android, web and desktop, and because email and calendar share one app, an invite becomes an event with one tap instead of a copy-and-paste job. Inside a Microsoft 365 organisation, shared calendars, groups and room booking work smoothly, and Exchange is still the calendar most large employers standardise on.

The free plan has edges. The desktop Outlook app, an ad-free inbox and the full Office suite wait behind Microsoft 365 Personal at $9.99 a month, and sharing calendars with people outside your organisation takes more steps than on Google. Buy nothing if your work email is already Outlook — the calendar you need is already there.

Fantastical is the paid upgrade for people who live on Apple devices and want the calendar to feel fast. Type 'Lunch with John at 123 Main Street on Tuesday' and the event appears with the right time, place and invitee, no form-filling involved. Calendar sets let you flip between work and personal views with one tap, or automatically when you arrive at the office, and Premium adds Openings scheduling links and meeting polls.

The gap is Android: Flexibits lists an Android app for 2027, so anyone with an Android phone should not buy Fantastical as their main calendar yet, and there is no web version either. At $6.99 a month, or $56.99 a year, it is the cheapest polished upgrade here — pick it if your devices are Apple and Windows, and skip it if Android is in the mix.

Morgen is built for the person this list is for: someone with a work calendar, a personal calendar and a family calendar on different providers, plus tasks scattered across other apps. It layers Google, Outlook, iCloud, Fastmail and Zoho calendars into one view, pulls tasks in from Notion, Todoist, ClickUp and Linear, and lets you drag them onto the day as time blocks. Its AI planner suggests a plan each morning and re-plans when meetings move.

The price is the catch. At $30 a month, or $15 a month billed annually, Morgen is the dearest solo planner here on monthly billing, and there is no free plan to fall back on after the 14-day trial. Pay it if you genuinely live across five calendars every day; if you live on one, Google Calendar does the job for free.

Reclaim.ai sits on top of Google Calendar or Outlook and defends the time you meant to keep. Tell it your focus-time goal, your habits and your lunch break, and it books them around your meetings, then moves them automatically when the day changes. The free Lite plan does this for real — it is not a trial — and Starter at $12 a month adds more AI agents, a longer scheduling range and calendar syncs between accounts.

Two limits matter. There is still no native mobile app, so phone use runs through the web, and iCloud calendars are not supported directly. Reclaim is also the tool Clockwise pointed its users to when it shut down in March 2026, which says something about where the smart-scheduling crown now sits.

Sunsama is a daily planner first and a calendar second. Each morning it walks you through a short ritual: pull in tasks from Asana, Trello, Todoist, Gmail and Slack, drag the ones that matter onto the calendar as time blocks, and close the day with a shutdown review. Focus mode keeps you on the current task, and there is one plan with everything in it, so there are no tiers to compare or features held back.

It costs $22 a month, or $17 a month billed annually, and there is no free plan — only a 14-day trial. Note the vendor's own pricing page still shows older $25 and $20 figures in its FAQ; the $22 and $17 figures come from the page's main pricing panel. Pick Sunsama if a calm daily ritual is what you actually need.

Any.do comes at the calendar from the task side: your to-dos and your events live on one timeline, so 'finish the proposal' and 'proposal meeting' sit next to each other instead of in two apps. The free Personal plan covers tasks, lists, reminders, the calendar and sync across devices, and the app runs on iOS, Android, Mac, Windows, the web and watches — the widest device spread in this list.

Premium is $7.99 a month, or $4.99 a month billed annually, and adds recurring tasks, WhatsApp reminders, AI features and location reminders. One warning: Any.do's own pages have shown different Premium prices, so read the total at checkout before you pay. Choose Any.do when simple lists plus a calendar beat a clever planner.

Notion Calendar is the calendar for people whose work already lives in Notion. The app itself is free on iOS, Android, Mac, Windows and the web, connects to Google Calendar, and shows Notion pages and deadlines beside your events, so a project due date and the meeting about it sit in one view. One-tap meeting notes link the calendar straight into a Notion doc.

Be clear about what it is: a view over Google Calendar, not a standalone calendar service, with thinner scheduling links and time-zone handling than the dedicated apps here. Plus costs $12 a member a month for collaboration. Pick it if Notion is already your workspace; otherwise Google Calendar is the simpler free choice.

Amie is the prettiest all-in-one in this list: calendar, todos, email and contacts share one timeline, and its meeting notes stand out because recordings happen without inviting a bot into the call. AI scheduling drafts replies and suggests times from your real availability, and the app runs on iOS, Android, Mac, Windows and the web. Pro is $25 a user a month, or $20 a month billed annually.

The price is the hard part. At $25 a month with no free plan — only a 7-day trial — Amie costs more than Fantastical, Morgen and Sunsama for a job Google Calendar does free. Buy it for the design and the bot-free notes, not for the calendar alone.

Motion is the most automated planner here. Its AI builds your day from your tasks and meetings, re-plans it when a meeting runs over, and keeps calendar, tasks, projects, docs and meeting notes in one workspace. Booking links and a meeting notetaker come with the AI features, and there is no free plan — only a 7-day trial that asks for a card.

Read the price carefully. The pricing page opens on the Teams tab showing $19 a seat, but one person pays $49 a month, or $29 a month billed annually — the $19 rate is the team annual rate. AI credits also cap at 7,500 a month on Pro. Motion earns its price only if the AI replanning saves you real hours every week.

Calendar.com is a scheduling platform with a calendar at its core, built for small teams rather than solo users. It unifies Google, Outlook and other calendars into one team view, adds booking pages, meeting polls and round-robin scheduling, and takes payment for events with custom branding on Standard. Individual and team analytics show who is booked and when.

The price needs reading twice: $20 is per user per month, so five people cost $100 a month, and annual billing brings it to $192 per user per year. Standard also caps at 10 users and 6 connected calendars. Pick Calendar.com when the team books meetings with outsiders all day; for personal use, the free tools above do more for less.

OneCal does one job and does it well: it keeps calendars on different providers in step. Most tools copy events one way; OneCal syncs Google, Outlook, iCloud and CalDAV calendars in several directions at once, so a meeting on your work Outlook calendar blocks time on your personal Google calendar automatically. Privacy controls decide which details cross over, and every plan includes unlimited booking links and a unified calendar view.

Starter is $5 a user a month billed annually, or $60 a year, for up to 2 connected calendars — but the month-to-month rate is not published, so check before buying if you will not commit to a year. OneCal is a specialist add-on, not a calendar on its own: you still need Google or Outlook underneath it.
