### 1/5 — 購入

*2026-05-17*

エラーページが出てプレミアム購入ができません。

**Developer response:** ご不便をおかけして申し訳ありません。
プレミアム購入ができない不具合について確認し、できるだけ早く修正いたします。
お手数をおかけしますが、最新版への更新後にもう一度お試しいただけますと幸いです。

### 4/5 — わかりやすい

*2026-05-12*

わかりやすくて猫さんの写真も登録出来て可愛いけど、今回のアプデ後に品種が登録されてなかったので登録し直したら、なせが16歳の猫さん人間年齢にすると80代のはすが136歳と表示されます
バグ？

(追記:アプリいつも愛用してます。外飼い猫さんの年齢だったんですね！納得です。バグじゃなくて良かった！丁寧な回答ありがとうございます！)

**Developer response:** イムジュ様

温かいレビューと、アプリをご愛用いただきありがとうございます😊
猫さんの写真を可愛く登録していただけて嬉しいです！

今回のアップデートで猫の品種選択が雑種（MIX）の場合、外飼いに計算されておりました。
・室内飼い： 16歳 → 80歳相当（こちらが正しい年齢です）
・外飼い： 16歳 → 136歳相当（現在表示されている年齢）
外飼いの猫ちゃんは、厳しい環境で生き抜くため、同じ12歳でもより高齢に換算されます。
次回のアップデート時に修正いたしますので、今しばらくお待ちください。
ご不便をおかけして申し訳ございませんでした。16歳の猫さん、大切に育てられて素晴らしいですね✨これからも健やかに過ごせますように🐱

### 1/5 — ありえない

*2026-05-10*

猫12才なのに
人間だと102歳
間違い❓

**Developer response:** ねこと枕様

貴重なレビューをありがとうございます。また、大切な猫ちゃんとの12年間、おめでとうございます。
102歳という計算結果についてご説明させていただきます。
実は、猫ちゃんの年齢換算には「室内飼い」と「外飼い」で大きな違いがあります。
・室内飼い： 12歳 → 人間の64歳相当
・外飼い： 12歳 → 人間の104歳相当（こちらが表示されていたかと思われます）
現在のバージョンでは、雑種を選択すると自動的に「外飼い」として計算されておりました。
次回のアップデートで、改善いたします。
ご不便をおかけして申し訳ございませんでした。

### 5/5 — I have no idea when my dog was born

*2024-09-15*

I thought I’d find out here

**Developer response:** If you know your approximate age, make your birthday the anniversary of that year!

### 1/5 — So bad I deleted it

*2024-06-11*

First of all, I took an image of my cat and said use photo and it said that my cat was one month old and it’s definitely older than that
