### 5/5 — THX

*2026-04-08*

写真のバックアップが出来ました。ありがとう御座います。

### 5/5 — ありがとうございます

*2026-01-15*

これまでカメラロールから写真を選択して転送する方法だと、一度に大量に選べなかったり、転送後に選択が解除されてしまって「どこまで転送したのかわからない」という不便さがあり、安心して削除できませんでした。
このアプリはその問題をきちんと解決してくれました。写真や動画を自動で順番に転送してくれて、転送が完了したものだけを確実に削除できるので、とても安心感があります。
ストレージ整理が一気に楽になり、本当に便利なアプリだと思います。
