### 5/5 — お願いがあります。

*2026-07-15*

1gの体重管理お願いします。月々ではなく1回の課金なので課金で使うとめちゃくちゃ便利ですが
1キロ以下の子の1gが大切なんで表示できるように
してほしい。
それがあれば最高のアプリです。

### 4/5 — エクスポート機能が欲しい

*2026-03-16*

とても良いアプリですが、不足の事態でデータが消えてしまうことが怖いので使わなくなってしまいました。
ペットの記録が消えることほどショックなことはないと思うので、データをエクスポートできる機能を切望します。
その機能があれば、他の内容はとても良いアプリです。

### 5/5 — 多頭飼いには重宝します

*2025-09-13*

猫の情報がすぐに確認ができてとても便利だと思います

### 4/5 — Useful, but missing metric/imperial switch

*2025-03-13*

Seems like a helpful app for tracking pet weight. I’ve just started using it. So far, the only negative is that I don’t see an option in the app for switching between kilograms and pounds.

### 4/5 — シンプルで使いやすい

*2025-01-15*

ねこたちの年齢を確認しやすくするためにインストールしました。超多頭飼いなので、無限にねこ追加できて助かります。課金しました。
カレンダー記録もつけられるので、爪切りや通院の日をメモできて最高です。
できれば供養ページの写真がもう少し大きいと嬉しいです。黒背景であまりに寂しいので…。

### 3/5 — 生存期間

*2025-01-02*

享年などを入力する事によって記録停止して記録出来たら良いなって思いました。

### 5/5 — Really great!

*2024-07-12*

I especially like the memo and weight parts. Just wish I can change kg to lbs.

### 5/5 — とても便利です

*2024-06-13*

体調や受診記録などもメモできて、とても便利です。ただ、入力し忘れていた過去のメモを残したいと思ったのですが、月日と時間は選択できても、年までは選択できず。年まで選択できるようになると、記録忘れ等あった時も追加で残すことができていいなぁ、と思います。改善されたらとても嬉しいです。

### 5/5 — Cute! But cat died🥺😢
