Leave a Review Proton Calendar
  • Lacking

    I’ve been testing for a few months and provided feedback several times, and they showed no interest in making any improvements. The app doesn’t allow for email notifications. The web calendar allows email notifications but the emails don’t tell you any details like the name of the event or the time so it’s pretty useless. The link in the emails opens the web calendar not the app. When I share feedback like this, I am told that’s the way we designed it. Pretty disappointing as I was hoping to switch from google but I rely on email notifications and these don’t work.

  • App has very slow loading, almost unusable

    I use the entire Proton suite of products and migrated from Google Calendar, but the iOS app is INCREDIBLY slow to load to the point of being unusable. It takes several minutes just to load the app, and several more minutes to view any events or scroll to other views ie daily, weekly, monthly etc.

    The web app loads quickly, but it also does not load some changes or additions to other integrated/linked Google calendar events, also to the point of being unusable.

    Sounds like more server & processing capacity is needed to make this app load quickly and to be useful for productivity.

    Hi! We are sorry to hear about your experience with the app. In our latest version of the Proton Calendar iOS app, we introduced improvements to the app's synchronization and event loading. We suggest clearing the app cache and data from your device's Settings → Proton Calendar to see if that helps. If the issue persists, please report the issue to us using the in-app "Report a problem" button.
  • Thanks!

    Very thankful to finally have this for my iPhone. Love the ability to customize the alert time. Would appreciate the ability to set multiple alerts for an event
  • Great to see 1st round

    Good calendar.

    My biggest request is to be able to view my entire month like it shows now. BUT so I can see what’s happening each day at a glance with the time visible.

    Not just a dot for an event or more happening that day. I don’t want to click into days or agenda view. I want to see it like a desktop calendar or old fashioned paper calendar on your desk.

    That’s just my suggestion, it’s only avail on informant calendar right now or desktop versions.

  • Missing too many key features

    I want this to be good, but it’s just missing too many key features to use full time. No month view, no widgets, no settings really at all to customize in the app. Doesn’t adjust for time zone changes while traveling.

    Hoping they update soon.
  • Add support for multiple Proton accounts

    I use ProtonMail for my personal and business accounts but I can’t have multiple accounts in the calendar app. Please add this functionality. Ideally, you should be able to see calendars from all added accounts on one page without switching.
  • Improvement Needed

    Finally, Proton Calendar for iOS is here! There are two major missing elements: ability to quickly scroll through months in a multi-year view, and an “Add participants” option on the event editor. I hope these are high on the dev priority list.
  • Needs widget

    Would be cool to have a clean home widget that shows list of items due for the day. Also maybe a separate tasks app would be nice (as long as it still had a widget)
  • 💜 SO HAPPY 💜

    I know many features are still in the works, and I’m grateful you released the app anyway! I’m thrilled to have an encrypted calendar!!! And I know you’ll make it feature-rich given time. 🥰
  • Not The iOS Calendar Replacement You’re Looking For

    Great app and integration with Proton Products, but lacks many features that most barebones Apple product users use. Some examples: No ETA and notification of “When To Leave”, No autocomplete for Address field like iOS, No “Focus Status” integration with calendar events, No automatically adding to Proton Calendar from various’ apps “Share Menu” buttons, No “Hold On View To Create Event” like in iOS calendar
