### 4/5 — Could use a couple fixes but that’s it

*2026-08-03*

I’ve been using Ermine for a few years now & I love it! I customize the color based on my wallpaper, & I like how it shows my events as well as an overview! My complaint is that scrolling through events at the bottom sometimes makes the entire screen freeze until I click on another day.

### 5/5 — Great Calendars

*2026-05-17*

I always have Ermine calendars on my iPad and iPhone because they are more customizable and help me read more easily. They fact that you can customize these calendars with different colors help my poor vision and improve the accessibility features otherwise missing in the IOS platform

### 1/5 — Worked until it didn’t

*2026-01-27, version 4.0.0*

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.

### 3/5 — 사용후기

*2026-01-17*

잘 사용하고 있는데 요사이는 버그가 걸리는지 내용 확인이 잘 안되서 나갔다 다시 들어가기를 반복하게되요

### 3/5 — Doesn’t display enough events

*2026-01-10*

Would be great if the month long calendar widget could display events like the two week long one. Or if the two week long one could be expanded (actual size, not the option to cram 4 weeks into the same space)

### 2/5 — 大切な予定が突然消え、仕事にも私生活にも大きな支障が出ています

*2025-11-28*

問い合わせができないため、レビューにて失礼致します。

長くこのアプリに予定を預けてきましたが、ある日突然すべてのデータが消えました。
仕事のシフト、プライベートの予定、やることリスト──そのすべてをこのアプリに信頼して管理していたため、消失後は実生活に大きな影響が出ています。

再起動・容量確保・設定の再許可など、考えられる対処はすべて試しましたが復旧できませんでした。
残業記録や友人の誕生日など、過去のデータも重要で、どうしても取り戻したくアプリを再インストールしましたが、戻ってきたのはほんの一部だけでした。

ここまで頼りにしていたからこそ、悲しさを通り越して強い怒りを感じています。
なぜこのような事態が起きたのか、またデータを復旧する手段があるのか、誠実な説明と対応を求めます。
このままでは安心して使い続けることはできません。どうかデータの返還や復旧方法について早急に案内してください。

### 2/5 — I really loved this until it deleted my calendar 6 times in three months

*2025-10-21*

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.

### 3/5 — Widget never refreshes

*2025-10-17, version 4.0.0*

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)

### 1/5 — 最悪

*2025-09-09*

⚠️データが全て消えます。
※新しい予定も書き込めなくなります。
※ヘルプの通りに試行錯誤するもデータは戻ってきませんでした。

別のアプリの使用をおすすめします。

予定はもちろんその日の出来事を見返せるよう、日記のように書き込んだりしていましたが、ある日突然すべての入力が消えていました。
データが戻ってくることを期待して、何日かスマホの再起動・ストレージ確認・アップデートを繰り返してみるもどうにもなりませんでした。

大切な予定や仕事の予定などを書き込みたい方は、多少の不便さはありますがやはり、純正のカレンダーアプリを使うことを強くおすすめします。

### 5/5 — とても満足

*2025-05-30*

シンプルながら、必要十分な機能が備わっているので、愛用しています。

ただ１つだけ、ウィジェットで2ヶ月分を表示すると初日は問題ないのですが、数日経つと予定などが同期されず、「今日」のマークも数日前の位置のままになってしまいます。

次回のアップデートの際に修正してくださいますと幸いです。
