Comments on Proton Calendar: Secure Events for Android

★★★★★ Luk Ahmad · Jul 31, 2026

Great calendar to replace the Google Calendar after my googled life. But one thing Google Calendar is better at, is a full month calendar widget on home screen, Proton Calendar please do that :)

★★★★★ Geeta Tewari · Jul 10, 2026

Very good calendar app! Nice UI, no bloat. Great for the average user. Just waiting for a tasks feature 😁

★★★★☆ Roman Avdeev · Jul 17, 2026

Great calendar. The UI is pretty and the data remains private. The biggest issue is that it doesn't have an offline mode for creating events. Also, it's unintuitive that the end date moves when you edit the start date, I wish it could be unlinked in the event editor.

★★☆☆☆ Daniel Taylor · Jun 28, 2026

I'd like to use it, but the widget is so bad. The font is too big and there's far too much empty space. I like to have a small widget in the corner of the screen to see a few days ahead. I have to make the widget 4x bigger than the app I currently used to see the same amount of information. Since switching to Proton a few months ago this app is the only thing to disappoint me.

★☆☆☆☆ J. O. · Jul 19, 2026

Everything is paywalled. No choosing colors for different events (everything is gray), can only have 3 calendars (including holidays), and importing a calendar is glitchy. Don't waste your time and try another option.

★☆☆☆☆ Sango Date · Jul 26, 2026

The public holiday calendar of many countries is missing. It needs to be online to add any scheduling and needs signing in to work despite being privacy focused. There is no "no-sign in" or guest option, a bit disappointing all things considered. The clock-like time selection, and the theme was nice... that's about jt

★☆☆☆☆ J Carroll · Jul 26, 2026

This app is horrible. I transferred all of my events, including all of my family and friends birthdays. Several days later, I noticed all of my events were encrypted, and I could not access them. Proton customer service was almost non-existent. I did some research online. Apparently, if you ever change your password, all of your events get encrypted, and you get locked out. I finally got a response from Proton customer service, which simply stated there's nothing they could do.
