### 1/5 — 分数が表示されない

*2026-06-22*

課金してるのにも関わらず分数が表示されない。UV指数だけ表示されてます。それでは他のアプリと変わらない。

### 2/5 — 紫外線について

*2026-06-09*

良いでしょうが、少し改善してもらうとわかりやすくなると思います。

### 2/5 — 天気が違

*2026-05-11*

天気が全然違うのはなぜ？
晴天なのに小雨になっているから、紫外線指数を疑ってしまう‥

### 5/5 — ありがとうございます

*2026-03-10*

いつもありがとうございます！、

### 3/5 — 天気の反映が不明

*2025-12-14*

雨や曇りの日でも紫外線量が晴れの日と変わってないように思えます。天気が反映されているのか分かりにくく、その工夫があると高評価だと思います。

### 5/5 — ！

*2025-05-28*

すぐ、指数がでてきて使いやすい

### 5/5 — 質問

*2024-11-11*

「日焼けするまでの時間」とはどういう意味ですか

### 5/5 — 良い

*2024-07-29*

分かりやすくて良い

### 5/5 — よかった所

*2024-07-24*

見やすくて分かりやすかった！

### 1/5 — 信憑性が低い

*2024-06-21*

一般的に雨の日の紫外線量は、快晴時の30%とされていますが、このアプリでは雨の日でも快晴時よりわずかに低い程度の予報が出ます。
他の紫外線予報アプリも使っていますが、それらと比べると誤差では片付かないぐらい数値が高く出ます。
あまり信頼できないと思います。
