Quick answer: if you need one calendar app for work and life, use Google Calendar — it is free, everyone can access it, and virtually every scheduling tool integrates with it. The alternatives below win in specific situations: Microsoft workplaces, Apple ecosystems, power users, and people who book meetings with outsiders. A good calendar is also the foundation of time blocking, so it is worth choosing deliberately.
The best calendar apps compared
| App | Label | Best for | Standout features |
|---|---|---|---|
| Google Calendar | Free | Most people | Sharing, time zones, universal integrations, appointment schedules |
| Outlook Calendar | Free | Microsoft workplaces | Exchange/Teams integration, work-hour sharing |
| Apple Calendar | Free | Apple users | Built in, iCloud sync, clean design |
| Fantastical | Freemium | Apple power users | Natural-language input, calendar sets, meeting proposals |
| Calendly | Freemium | Scheduling with outsiders | Booking links with availability rules and time-zone detection |
Google Calendar: best for most people Free
Google Calendar is free with any Google account and remains the de facto standard. Sharing a calendar with family or colleagues takes seconds; events display correctly across time zones; and because every scheduling tool, video-call service, and to-do app integrates with it, your calendar becomes the hub rather than another silo. It also includes appointment schedules — a built-in booking-link feature that covers many people's Calendly needs at no cost.
Best for: literally everyone with a schedule. Watch out for: your data lives in Google's ecosystem. Official site: Google Calendar.
Outlook Calendar: best for Microsoft workplaces Free
If your employer runs on Microsoft 365, Outlook Calendar is already your calendar — and it is good. Meeting invitations, shared team calendars, Teams links generated automatically, and coworkers' free/busy visibility are all native. The personal version is free with a Microsoft account, so your work and life calendars can live in the same app without mixing data.
Best for: anyone whose workplace uses Microsoft 365. Watch out for: the interface carries decades of enterprise baggage; personal users without a Microsoft workplace usually prefer Google's simpler design.
Apple Calendar: best for Apple users Free
Apple Calendar is already on your iPhone, iPad, and Mac, syncs via iCloud, supports shared family calendars, and can subscribe to Google and Exchange calendars alongside your own. For Apple-only households it is the zero-configuration choice, and it handles time zones and travel time alerts well.
Best for: Apple-only users who want simplicity. Watch out for: sharing with Android or Windows users is clunky — mixed-platform families are better served by Google Calendar.
Fantastical: best for Apple power users Freemium
Fantastical is the upgrade Apple users buy when Calendar feels limiting: type "lunch with Sarah next Tuesday at 1pm" and the event is created; calendar sets switch your whole view between work and personal contexts; meeting proposals offer invitees several times in one email. The free tier covers the basics, while the most-loved features sit behind a subscription — check current tiers on Fantastical's official site.
Calendly: best for scheduling links Freemium
Calendly is not a calendar — it is the layer that stops "does Thursday work?" email chains. You set availability rules; it generates a booking link; invitees pick a slot that lands on your real calendar automatically, with correct time zones on both sides. The free plan covers one event type, which is enough for many freelancers. Paid plans add multiple event types, reminders, and team routing. Details at Calendly's official site.
Features that actually matter
- Sharing. Can your partner see your calendar in two clicks? Can colleagues see free/busy without seeing details?
- Time zones. If you travel or work with other countries, verify the app displays dual time zones and handles DST correctly — all five above do.
- Scheduling links. Google Calendar's appointment schedules or Calendly save freelancers hours every week.
- Integrations. Your calendar should accept events from your video-call tool, task manager, and booking systems automatically. Google Calendar has the widest integration ecosystem.
- Reminders. Multiple notifications per event, and travel-time alerts, prevent most missed meetings.
Once your calendar is set, put it to work: our time blocking guide turns it into a daily plan, and the best productivity tools roundup shows how a calendar fits with tasks and notes. Every free option above also appears in our free productivity tools guide.

Frequently asked questions
What is the best free calendar app?
Google Calendar is the best free calendar app for most people: it is completely free with a Google account, sharing is effortless, time zones are handled well, and nearly every other productivity tool integrates with it. Apple-only users can happily stay with the built-in Apple Calendar, which is also free and syncs via iCloud.
How do I share my calendar with family or coworkers?
In Google Calendar, open the calendar's settings and add people by email — you can let them see full details, only free/busy status, or edit events. Apple Calendar sharing works through iCloud invitations. Outlook offers similar sharing, including free/busy visibility for coworkers. For booking meetings with people outside your circle, a Calendly link or Google Calendar's appointment schedules is easier than sharing your whole calendar.
What is the best app for scheduling meetings with clients?
Calendly is the most established option: you set availability rules, share a booking link, and clients pick a time that lands on your calendar automatically with correct time-zone conversion. The free plan covers one event type. Google Calendar's built-in appointment schedules are a capable free alternative if you already live in Google's ecosystem.
Can I use two calendar apps together?
Yes, and many people do — for example, Google Calendar for personal life and Outlook for work. The reliable way is to subscribe to one calendar from the other (both support iCal feeds) so everything shows in one view, while editing stays in the native app. Apple Calendar and Fantastical can also display Google and Exchange calendars alongside iCloud.
