User Reviews

Users laud Ermine's polished, customizable UI and calendar integration with strong widget support and privacy. However, recurring issues center on widget reliability (dates not updating or displaying incorrectly) and data syncing problems (events disappearing, calendars wiped). Some requests also seek expanded photo/widget functionality. Overall, Ermine looks great and functionally rich, but reliability—especially around widgets and data sync—needs improvement.
Pros
  • Aesthetically pleasing UI with strong customization of colors and widgets.
  • Easy to use and intuitive calendar experience.
  • Excellent widget support that integrates with existing calendars.
  • Syncs across multiple calendars.
  • Strong privacy: does not collect user data.
Cons
  • Widget reliability problems: dates not updating, wrong dates, or blank/broken widgets.
  • Calendar data can disappear or calendars get wiped, with syncing failures.
  • Photo widget limitations: only a single event shown and limited photo/shuffle options.

I loved this app for multiple years and depended on it as my calendar for EVERYTHING. Until all of a sudden all of my events completely disappeared. There is no update that I missed or any button that I would have clicked in the app. Do not depend on this app to keep your important life schedule in.

This app is great aesthetically. Easy to use and has simple customizations. HOWEVER, I don’t know why but for some reason in the past three months, I’ve had my calendar completely wiped six times. I’ve used this app for two years and had no problems, even recommended it to friends. Never had this happen before now. Once, okay I get it maybe I messed up and so I fixed all my settings so it’s all synced and backed up. Twice, I thought was odd but chalked it up to an iPhone update gone awry even though my settings were set to sync. HOWEVER SIX TIMES????? Insane. The app support/help page is a JOKE. They just ask you to resync your calendar? ITS BEEN SYNCED. There is no reason why my calendar just decided to end itself six times over the period of three months. This has pushed me to look at other calendar apps because some of these appointments were set months ahead of time and I have cannot remember them now, no thanks to this app. Sure it’s pretty, but it’s empty, just like my calendar.

The multi-month widget view never refreshes/updates the date. I have to constantly “edit” the widget, pretend to add it again and then it updates the date. It’s becoming a pain bc I can’t really trust what the widget is showing me. Anything I can try or is this a known issue? iPhone 15 Pro iOS 18.7.1 (22H31)
