Our take
Google Calendar isn't flashy, but it's the one app everyone already has and actually uses. If you're not doing something complex, there's no reason to pay for anything else.
If your workplace runs on Microsoft 365, Outlook Calendar isn't just a good choice — it's the only choice that makes sense. The integration with Teams and To Do alone makes it worth it.
