This app doesn’t darken your screen. 
It only changes the brightness you already have it set on

### 2/5 — 5段階しか記憶されない

*2026-02-24*

明るさが100段階で数値化され調整できるが、保存は5刻みでしかできない（例:｢37｣で保存しても実際に保存されるのは｢40｣）のが残念。

### 2/5 — 何世代前のiOSまで対応してたのか

*2026-02-20*

iOS26.2の現在、このアプリで明るさ調整するとそのまま大元の明るさ設定にも反映されてしまいリセットされなくなる。
非常に使い勝手が良く愛用してたけど、更新する気がなさそうだし削除します。
