The app needs to update

### 5/5 — 365もアップデートを！

既存の365も最新OS対応にアップデートして下さい。
過去の履歴が表示できなくなり
悲しい思いをしています。
何卒宜しくお願いします。
勿論プロも使用してます。

### 5/5 — 更新がきて嬉しい

*2021-05-09*

ios14.5で開けなくなり困っていましたがアップデートされて良かったです。カウントアプリは色々と試しましたがやはりこのアプリが最高です。欲を言えばアイコンは以前の白のままが良かったです笑

### 5/5 — 対応、ありがとうございます

*2021-05-08*

デベロッパーが対応しないと開けなくなっており、半ば諦めて他のカウンターアプリをすでに使っていました。
また使えるようになり、大変ありがたいです。

ただ、以前は設定でできたバッジの表示ができなくなっているようです。

対応して頂いた上に恐縮なのですが、バッジの表示もとても便利な機能だったので、よろしければこのバッジ機能について、再度のご検討をして頂ければ幸いです。

### 5/5 — 14.5対応ありがとうございます

やっぱり365アプリが最高です。もう、アップデートしてくれないのかと思って、色々探しましたが良いのがなくて諦めていた所です。今後もよろしくお願いします。ずっと使い続けます

### 4/5 — 便利

*2017-09-25*

カウントダウンも出来て写真も保存できる。記録するのに重宝します。他のアプリも使ってみたけどこれが今は1番。画面の色を可愛く出来たら楽しくなるのでこれからに期待してマイナス1ごめん。

### 5/5 — 便利に使っています

記念日とか入れておくと絶対忘れないし、前回床屋へ行ったのいつだっただろうなんて使い方しています。
欲を言えば◯◯◯日経過も表示してくれると楽しいです。
