### 5/5 — Very happy

*2026-05-23*

Very happy with my battery app

### 5/5 — 有能

*2026-05-19*

ちょくちょく確認しているが、残量がよく分かり重宝しています。

### 5/5 — ワンタップ

*2026-03-29*

電池で1番知りたい情報は、今現在の残容量だと思うが、ワンタップで確認できる。

### 1/5 — Horrível

*2026-03-12*

Interface feia e cheia de botões desnecessários. Não cumpre o que promete, pois não analisa a bateria. 
Desinstalei no mesmo instante. 
Nota zero 0.

### 4/5 — イイ感じ

*2026-03-12*

iPhoneとiPod touchユーザーです。レビューを見て気になったのでダウンロードしてみました。右上の残量表示はオンにしていますが、容量も軽いしあって困らないと思います。あと、サムネ(？)みたいなところにもある通り普段なら見ることが無い情報とかも載っているので、見てる分には楽しいです。ただ、iPod touchユーザーには必須のアイテムです。５ＭＢなので入れることを強く勧めます。ただ、iPhoneユーザーにとって見れば右上のバッテリー残量をオンにして見た方が早いので、このアプリはあくまでも好きで入れるという感じになりそうです。

### 5/5 — Great app!

*2024-05-02*

But, please, make that text about battery percentage as thrice as larger - it's not very comfortable as a widget with its current size.

### 5/5 — Guau

*2024-04-10, version 2.1*

Si muestra el porcentaje exacto de la batería

### 5/5 — Battery at a glance

Thanks. This app is exactly what I was looking for. I can see immediately the battery level etc without putting on my glasses! Thanks again.

### 5/5 — ★ 最高です！

*2023-10-13*

なにしろ、シンプル。

しかも、潔い！ 言うことなし！

### 5/5 — Genial

*2023-10-05, version 2.1*

Me resulta muy útil porque me permite ver el porcentaje en letra grande
