### 5/5 — 1番便利なカレンダー

*2026-07-28*

機能が豊富で、とても使いやすいです。他のカレンダーでは昔を表示制限されてますが、このカレンダーでは昔も(例えば1950年代など)も表示できるのでOK !! 素晴らしいです。

### 3/5 — Can’ remove or change attached picture

*2026-06-26*

The app can attached picture via tapping the selected data. After that, you can’t remove or change the one  you selected. Does it have any solution?

**Developer response:** On the event edit screen, please swipe left on the attached data. A delete button will appear. Thank you for your cooperation.

### 5/5 — Brilliant Calendar

*2026-06-03*

I use this brilliant calendar all the time but would appreciate the developer verifying that it’s compatible with MacOS as I’d like to use it across my Apple platforms. It is streets ahead of the Apple calendar and the scroll is much better as you can see parts of this month and next month or last month and this. 

Please please make it available full on MacOS

### 5/5 — Brilliant

*2026-06-03*

Not been a user of this app for long but it's my go to everyday now. Well worth the money to remove ads and a really cool looking app. I like how you can make it just how you like it with a lot of options. The widgets are really good as well. Would recommend for sure. One of the best imo.

### 5/5 — Hands down the best calendar app.

*2026-03-31*

I’ve been using this app for 2 years now. This app has it all plus it’s not subscription based! Syncs perfectly with the iOS calendar. This is the best calendar app out there.
