### 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.

### 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)

### 4/5 — Love except

*2025-04-03*

Love it except the fact that the date won’t update

### 4/5 — Needs a bug fix

*2025-03-27*

Lately the date isn’t updating and I have to uninstall and reinstall the widget for it to update 😭 so sad bc I looove this app, i’ve been using it for so long and I can’t find another calendar widget app that does what I want. but I think i’m going to have to find a new app now. I hope they fix this issue because otherwise this is the perfect calendar widget app

### 3/5 — Great app one problem

*2025-03-08*

This app is great on the way it connects to your calendar and can edit your calendar on the app. My issue is we need to be able to add more events on the photo widget. Only showing one event is frustrating when the color one allows multiple events as well as showing the calendar itself. If you could allow the photo widget to show the full calendar as well as multiple events it would be a much better calendar widget app.

### 3/5 — ウィジェット不具合

*2025-03-04*

2025/03/04時点
iOS17.6.1
アプリ最新状態

他の方も記載されてますが、自分もウィジェットで2ヶ月分のカレンダーを表示させるために利用しておりました。

2025年2月上旬にtodayが動かなくなり、ウィジェット置き直しなど数回しましたが根本解決に至らず、2025年3月になった今も2月28日のまま4日経ちましたので、別のアプリに乗り換えました。

### 2/5 — desperately needs bug fixes

*2025-02-07*

was a really helpful app for a while, but now the bugs and unresponsiveness when trying to edit a new calendar widget make it unusable for me. even things like changing days of the week colours, languages or fonts makes the entire app unresponsive until i restart it.

### 3/5 — Great app but needs some bug fixes

*2024-12-24*

I love the widget and customisation options this app offers. However, probably once every couple of months the date on the calendar will not change. It could be 30th March and the calendar will be stuck on the 20th. It’s really frustrating as the only way to fix it is to delete the widget and reinstall it again. Please fix this bug.

### 4/5 — Great app, needs update

*2024-12-15*

This review is mostly a note to the developer. I will happily change my review to 5 stars and update my review accordingly once this minor inconvenience is remedied 🙇🏻‍♂️

Thank you for this great app! I use it with my wife and it’s very helpful for us!

Device specs:
always latest iOS, iPhone 16 ProMax

App:
paid for (not the free version)

Issue:
the home screen widget does not *visually* automatically refresh and update. The info *is* current if I click into the widget to open the app. For example, I was looking at the widget just now; it said the current date is December 13, 2024. It shows the correct info when I open the app, but widget was incorrect.

Observations and workaround:
I’ve discovered that the widget date *will* update if I resize the widget. For example, I just changed the widget size from the “medium” size to “small,” then back to “medium” and the date updated. However, the date then gets stuck on whatever the date was the last time I resized the widget. For example, the last time I resized the widget was on December 13.

Miscellaneous info:
I’ve tried finding an in-app setting to correct this, but see no relevant option. I’ve also searched in my device system settings but didn’t find any relevant options. For example, I looked in my “background refresh” settings, but Ermine wasn’t listed there.

—————————

Thank you for your time and great efforts developing this aesthetically pleasing and useful app! I also see you have a “time sheets” app that I’m going to try out.

### 4/5 — 업그레이드 하고 입력하는거 너무 불편해요

*2024-10-30*

몇년째 쓰고 있는데, 얼마전에 업그레이드 하더니 시간 선택하는거 세상불편하게 되었더라구요.
시간 설정하는데 대체 몇단계를 가야하는지 이해가 안가요.. 2-3년은 쓴거같은데, 참다참다 요즘 쓸때마다 짜증나서 안되겠어요, 어플 삭제합니다. 그래도 꽤 오랫동안 무료로 잘 써서 별 4개 드려요.

### 3/5 — ウィジェットの不具合

*2024-09-30*

シンプルで使いやすいので数年前から活用していたのですが、ほかの方のレビューにもあるように、最近、ウィジェットの日付がずれてしまうことに加え、設定でカラーウィジェットを編集しようとすると、アプリがフリーズして操作ができなくなります。

再起動しても同じで不便なので、仕方なく別のアプリに乗り換えました。元に戻したいので、改善していただければ助かります。

### 4/5 — 알람기능이

*2024-09-30*

갑자기 알람기능이
사라졌네여.
확인후 조치 부탁 드러요

### 3/5 — 時間の設定が使いにくくなった

*2024-09-07*

使いやすくて気に入ってたのですが、少し前のアプデで時間の選択がダイヤル選択？からプラスマイナスのボタンを押す方式がデフォルトになってしまい、つかいづらいです
一応ダイヤル式も使えるのですが、今までは終了時刻も自動で開始時刻より後に設定されたものが手動でやらなくてはいけなくなったので終了時刻は確定してないけど開始時刻は入れたい時に一手間増えて不便です。

### 4/5 — 便利に使っています

*2024-08-31*

デザインがシンプルで使いやすいです。 アップデートされ、各日を長押しすると予定を記入できるようになり、時間設定もしやすくなったことが結構便利でありがたいです。 長く使っていて過去の予定も残っているので他のアプリに変えることはないかなと思います。
デザインがシンプルで使いやすいです。

一点だけ気になることがあります。

予定を入れた日は、曜日関係なく日付が赤色になるのですが、土日が分かりやすくなるよう色を付けたいと思い、課金してみました。
その後カレンダーを確認したところ、色をつけた土日に予定を入れると日付が赤色で統一されてしまうため、ほとんどつけた色が分からない状態になってしまいました。
予定が入っていることの表現が、曜日に色をつけた場合に便利になると嬉しいです。
また、課金後のイメージを画像で見れると良かったと思いました。

### 3/5 — Cute private calendar 🤍

*2024-08-23*

I was using iOS Calendar and Simple Calendar side by side. This was because iOS Calendar offers the yearly view while Simple Calendar offers monthly view with highlighted events based on my color preference. If Ermine can provide these features and offer event reminders and more customizable repetition (such as every 5 days, etc), I will 100% switch over. As a bonus, Ermine does not collect data which is hard to come by when looking for apps nowadays.

You can change the app icon, too. All I did was tip the developers which I believe they deserve anyways. The Ermine Pro offers customization regarding Widgets, not necessarily your in-app experience.

### 2/5 — Not pleased

*2024-08-09, version 3.1.1*

I use to be entirely dependent on this app and the update honestly ruined the functionality, we have to use a plus and minus sign to change the time and we can’t even change it from pm to  am without having to run thru the 24hrs.

### 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.

### 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。

### 1/5 — Текущая дата не обновляется в виджете

*2025-02-08*

В виджете текущая дата зависает на каком-то числе и так и стоит не обновляясь, например сегодня 7 февраля, а в виджите текущая дата кружком отмечена как 3 февраля. Обновляется только после удаления и добавления виджита.

### 1/5 — widget broken; not showing right date

*2025-02-05, version 4.0.0*

it’s now Feb 5 and yet the widget still shows Jan 31 with no way to fix it….

### 1/5 — Can’t add anything

*2024-05-02*

I downloaded the app and connected to my calendar. The plus button which I’m guessing is to add events and things to your calendar is grey and not working. I can’t add any events which makes the whole thing completely useless

### 1/5 — なぜ？

*2023-11-21*

iPhoneのアップデートがされてからホーム画面のウィジェットが真っ白で毎回開かないとカレンダーが見れない😭

### 1/5 — バグ？

*2023-10-04*

ウィジェットを利用すると、祝日名という欄に予定が表示され、それ以降の本来予定が表示されるべきであろう欄に正しく反映されない。 課金したのにこれでは非常に残念。 また、複数の予定がある場合も1番最初の予定しか表示がされず、さらにその予定がすでに終了しても表示が切り替わることがないのは実用性に乏しい。 問い合わせようとしたが、アプリ内の問い合わせリンクがグレーアウトされている始末で、他のレビューにある通り顧客の意見を聞く気はなさそうな印象を受けた。不親切極まりない。 他にもカラーカレンダーの背景色は変えられても文字色が変更できないなど、微妙なところに妥協を感じる。 iPhone15なので未対応なのだろうか。 シンプルさを気に入って愛用していたので課金もしたが、今のところ追加の課金の必要性を感じない。

### 1/5 — Calendar wrong

*2023-10-01, version 3.0.0*

Calendar is wrong. Dates are on the wrong days of the week. Horrible app.

### 1/5 — Bug

*2023-09-16, version 3.0.0*

App updated and now my widget is just a blank field with no calendar on it

### 1/5 — Not app friendly

*2022-09-20, version 2.1.0*

I don’t really know what it does? I thought it was going to make the calendar different colors at least.  Tue directions aren’t clear . I want a refund but I have no idea how to get it back. I’ve tried several times . Waste of money

### 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

### 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。

### 5/5 — Love it but

*2025-02-28, version 4.0.0*

The double calendar widget should have some buttons to let you scroll through other months without opening the app

### 5/5 — So far I love it!

*2024-10-27*

I’ve been using the fitness apps Hops and Standland for years and I was looking at the other apps they have, saw this one. So far I am loving it! The main reason I am so excited about this app is first, it is so easy for me to look at my monthly appts all at once and that includes PAST appts!! I was searching forever on how to restore my dates/appts on iCal and frustrated gave up and what’s this…? It’s on my Ermine calendar app!! All of it!! Without even doing any searching!!! Love the color options, syncing all of my calendars at once and again, my past appts/dates. THANK YOU SO MUCH!! 😊

### 5/5 — Great little calendar

*2024-10-06*

I’ve made this my default calendar and I love this widget. Very easy to navigate.

### 5/5 — 이번 업데이트 구림 ㅠ

*2024-09-04*

UI 왜이래요 진짜 불편함… 원래대로 되돌려주세요

### 5/5 — Prefer over Google

*2024-07-23, version 3.0.1*

Very good calendar. Simple to use and understand. No complications. I particularly like the fact that it doesn’t have a bunch of ridiculous non official dates and holidays.

### 5/5 — Constantly wiping calendar picks

*2024-05-23, version 3.0.1*

Recently, it started unchecking my synced calendars, making my widgets blank. Not really sure what to do about it, but before that started happening, it was a really great app.

### 5/5 — Ótimo aplicativo

*2023-12-30*

Falta o aplicativo mostrar o calendário em português.

### 5/5 — The Best

*2023-07-30*

After much research, I've found the perfect event/calendar app for my iPhone 14 Plus. 
For a very small one off payment, several features are unlocked to enable more personalisation.....such as colouring of individual dates, choice of font, etc. And what I like most of all is being able to show upcoming events for the day alongside the actual full monthly display in a single widget. Couldn't find anything similar in this respect elsewhere. A deserved 5 stars, more if I could.
