Comments on Tuta Calendar: Secure Planner for Android

★★★★★ Gencho Draganov · May 4, 2026

I've been a user of both the calendar and mail apps and love them both. Functional, clean (which is what I admire) and most importantly private. I haven't found something I want out of my calendar app missing as of writing this. One minor preference - I liked the previous widget 😅 Both the small drawing that showed up when you had no events and the fact that events for the upcoming days showed up only when you scrolled down. Would love if there were options to choose between the two 😁

★★★★☆ Sara Rose · Jun 9, 2025

Don't know why this has to be a separate app, but it's NOT a suitable replacement for the Google Calendar widget, unfortunately. Otherwise it's fairly decent.

★★★★★ Johannes A · Nov 6, 2025

A clean and easy to use calendar app that syncs with my tuta account, the design style matches the mail app, and the home screen widget is really useful too! Thanks!

★★☆☆☆ Ashley Redzko · Jun 18, 2025

I love Tuta mail, but this calendar widget leaves a lot to be desired. Some major pain points for me: - No option to subscribe to or manage outside calendars. - Unable to copy events to easily make a new one. - Reminders and notifications can sometimes fail to go off or go off on the wrong day or time if you update an event time. - No daily agenda view. - Clock widget for selecting time of events frequently breaks. I had to make the unfortunate choice to go back to Google calendar for now.
