Secure Calendar
UI is pretty good, a fine comprimise for zero knowledge personal and shared calendars. Looking forward to the 2026 app re-write. I tell all my friends to use ProtonCal.
Proton isn’t focused on apps
I’ve been a subscriber for a couple years now. In that time, I don’t think any of their apps have had an update. I’m glad a company exists that’s focused on privacy but their apps are stuck in 2005. It’s increasingly frustrating that you can’t do basic things - like set Proton Calendar as your phone’s calendar application.

Missing important function
There is no ability to search for an event (past or upcoming). This is very inconvenient and frustrating.
Can’t delete canceled appointment invitations.
VERY VERY ANNOYING!!
Very hard to use
This app doesn't have a responsive UI and the UI is broken in windowed mode - windowing/maximising stops working and the UI becomes unusably tiny. It's almost been a year since iPadOS 26 has come out and it's still this way. I'm starting to look elsewhere for my calendar needs.
Slow and clunky
This is the only one of the print on apps that isn’t useful. I find the whole process of adding meetings are invites to be slow and clunky and I’ve noticed it the number of times and I don’t get any notifications for my calendar events. Notifications are turned onbut not this one.
Feature Request
Hi! I really like the app. I would love it if you could add Liquid Glass to it.
The best and doesnt track me as a product!
Transitioned for google and im so happy. Proton ia gret.
Too basic
Misses too many options available in other calendars like Outlook. Search box for example would be nice so one can search for specific scheduled meetings or appointments
Great with one but
The app is great, driving on daily bases. BUT: ability to add events to non-proton calendars is the key feature that is missing unfortunately
Minute change suggestion
This is a good app. I’d recommend adding a feature that allows users to change the minute column to increments of 5 instead of 1. That would reduce options from 60 to 12, making scheduling more efficient, and few people schedule at times outside of increments of 5.
Need watch app please
Works great on phone and iPad but missing watch app. Add watch support and I’ll change rating to 5 stars
No offline mode
the fact that this doesn’t have an offline mode is unforgivable
Great overall
I’ve been using the app for several years now. Started using it in its original beta and have never looked back. It’s come a long way with functionality and still has a long ways to go but overall I love it and the peace of mind it brings knowing that big tech and other online trackers don’t have my entire life’s history documented on their servers to sale to who knows who. My biggest wish/want is for Proton to finally release the new calendar app that allows for offline mode and the to-do features built in…was originally announced so long ago and keeps getting kicked down the road so if that could be released any year now, that would be great. Other than that, I’d recommend this tech suite to anyone.

App keeps freezing and events don’t appear
I’ve completely switched over to Proton from Google. However, the calendar app keeps freezing. At least once per time I go onto the app, and then I have to close it and re-open it. It also won’t always load my events. Instead, the calendar opens empty. And then when it DOES correctly display my events and I go to tap on one, the app freezes. This needs to be fixed.

Excellent Calendar!
Proton calendar works great and is the best for privacy!
No Year View
Put in view by whole-year & put the current-year next to the month in the month view, not just for previous & future years.
Edit: Hi Devs, thanks for reading my reply. I want to use this but difficult to switch when you have less, not equal or more features than the native Calendar app on iOS 🙂 Thanks!

Número uno fan
Been with proton for nearly a decade. Big fan of what they stand for. I use this calendar instead of apples calendar. Easy to use, great reminders.

Good, but room for improvement
This app is pretty good, but when someone shares an event with you, you have almost no control. I just want to change it so that shared calendars are different colors. I also can't delete a shared event- not me doing the sharing. I want it separate from "my calendar". I think you can do a lot of this from desktop, but not from the app.
