Ratings and Reviews
No native iPad support
Why not an universal app like all the other Proton apps? Really a bad user experience on an iPad :(
Developer Response ,
Thank you for your review! The app is designed primarily for iPhone, but we’ll share your request for iPad support with our development team to help prioritize future updates.
iPad support
I love the proton ecosystem but the fact that the calender has an iphone aspect ratio on ipad really bugs me. Once that is fixe i will gladly give 4 stars
Developer Response ,
Thank you for your feedback. We're working on enhanced iPad support, and it's included in our upcoming roadmap: https://proton.me/blog/mail-calendar-roadmap-spring-summer-2025. We hope you'll reconsider your rating once iPad support has been introduced.
No modification or cancellation of single events in a series
I love Proton but the Calendar functionality is really rubbish: why is it not possible to modify or deny a single event in a reoccurring appointment without modifying or cancelling all?
Developer Response ,
Hi! Thank you for your feedback. We have an existing request for this feature, and we'll add your vote to help the team prioritize future improvements. If you have any additional suggestions on what we can do to improve, contact us at https://proton.me/support/contact to let us know.
