How to choose
Start with the plan you need
There are 162 free plans among the 197 apps. Check what the free plan includes before comparing paid prices; the board also shows each app's paid starting point where provided.
Some listed apps are free or freemium. WebCalendar and Mozilla Thunderbird are marked free, while Lark, Calendar.com, Slotly, Tandem, Everest and MiCal use freemium pricing.
Match your devices
Web access appears on 116 apps, followed by iOS on 113 and Android on 98. Desktop coverage is smaller: 64 support macOS, 39 support Windows and 33 support Linux.
Choose an app that covers the devices your household or team already uses, especially if calendars must stay available away from a desk.
Check daily scheduling tools
The comparison includes shared calendars, time blocking, scheduling links and calendar sync. These features cover group visibility, reserving focus time, letting others book time and keeping calendars aligned.
Video meeting support is also compared, so check it if appointments need an online meeting option.
Use a trial before paying
The list has 76 apps with a free trial. Slotly lists a 14-day trial and paid plans from $10 per user each month; MiCal also lists a 14-day trial and starts at $4 per user each month.
Tandem lists a free plan with paid service from $20 per month. Trial length and billing units differ, so compare the details shown for each app.
Look for open-source options
Only three of the 197 apps are marked open source. If having code that can be inspected or changed matters, use that mark alongside the free-plan and platform details.
