Has not been fully tested on smaller screens

Defining events using a Wednesday, either the year or time of day gets truncated with "..." on the screen on an original iphone SE. Showing a year as "20..." doesn't narrow much down within my anticipated lifetime.

If you kept to the short format as on the date selector itself (Weds rather than Wednesday) then this would not happen.

Then if I view an event, where there's more than enough space on the screen, the day name doesn't even appear at all. Why such inconsistency?

Please test and ensure the app is usable on all officially supported devices, otherwise what's the point of them installing the app?

Plus when defining or editing an event, accidentally scrolling the end before the start goes and shifts the start rather than prevent me from setting an impossible range. This makes it far too easy to make mistakes.

If I'm editing one end of the event range it should not modify the other end.

Yes it's a Proton app and I don't doubt very secure and so on, but usability-wise this is nowhere near your other apps yet.

Hi! Thank you for the detailed and extensive feedback. We've shared it internally with the team for future consideration. Could you report this directly through the "Report a problem" feature in the app menu so we can have more details on your device and properly document your feedback? If possible, please send us a video of the behavior you've described when editing an event. Our community's input is really important to us.

Widgets need to come out soon!

I’m not going to be too harsh on Proton as they already have too many products to work on. They have been releasing so many new things in such short period that I can understand there can be some delays on new features equally released among all available products. However, I would love to have a full replacement for the Apple Calendar with full integration on my phone and hopefully a stand alone Contacts App where I can search for my contact and call them straight away without having to go through the mail app. As for now I will keep supporting unconditionally, till the day there is some massive controversy regarding privacy and Proton. Touch wood ✋🪵 keep doing what you do, I’m reading your blog posts every time there is a new release.

Good start, hoping for regular improvements

Pleased that the iOS calendar app is here! It’s looks great & does the job. There is definitely room for improvement - small refinements like providing UI feedback when you’re swiping between days so you can see what’s going on. I’d also like to see calendar events displayed in a month view to get a sense of what I have coming up without having to select individual days (for me, it’s the most useful view in the Readdle Calendars app). Look forward to future releases.

Developer Response ,

Hi! We'd just like to let you know that we've now introduced month view in the Proton calendar app, as you requested. You can now see more of your events at a glance and easily switch between views from the side menu. We remain committed to improving our apps based on our community's feedback, so feel free to edit your review with any additional suggestions you may have.
