### 1/5 — 最低

*2025-03-19, version 1.2.5*

メニュー画面から動画をあげようとしてもクラッシュして半年以上経過…直す気あります？？
課金分返してよ…(´･ω･`)

### 2/5 — 落ちる

*2025-01-20, version 1.2.4*

スマホアプデ後、動画リストを見ようとすると落ちるようになった。
対応してください。
iOS18.2.1

### 1/5 — アプリ落ちる

*2024-12-17, version 1.2.4*

動画リストを開くとアプリが落ちて使えない。

### 1/5 — ドラレコとしては使えない

*2024-12-08, version 1.2.4*

通勤時の自転車で使用するためにアプリとHUDアドオンを購入。
使用感やデザインなどは悪くなかったが、撮影時間が20分程度なら問題無かったが1時間を超えるなど少し長くなると撮影した動画のリストを開こうとするとアプリが落ちるようになる。
運転時間1時間なんて当たり前に想定出来る範囲だと思うが。
まだ使用開始から2週間程度だが撮影時間が1時間を超えた事が二度あり、二度とも同じ現象に陥った。
そうなると過去撮影分を含めた全ての動画の再生、カメラロールなどへの保存、動画の削除が一切不可能となり、撮影した全ての動画ごとアプリを消して再インストールするしか方法が無くなる。
その状況でも録画自体は出来そうだが、確認出来ない動画が増えて容量を無駄に圧迫するだけ。
万が一に備えてと考えていたものの、再生出来なくなる可能性が決して低くはないアプリを信用は出来ないので、ただ金を無駄にした結果になった。

他にも問題点はあり、
・設定画面ではほぼ全ての項目が反応せず設定が不可能
・設定画面で唯一反応のあるDropboxの連携設定は進めてもレビューの承認がどうこうと出て結局連携は出来ない
（Dropbox側のアプリリストから連携承認させようとしても、そもそもこのアプリがリストに存在していない）

普段は有料アプリがどんなに期待外れでもレビューをしたりはしないが、無料アプリどころかテスト段階のような品質のまま堂々と販売、何年も前にレビューされているDropboxの連携問題への対応の遅さ、何よりもドラレコを謳っておきながら撮影した動画が一切確認出来ない状況になるという致命的なバグがある現状ではこのアプリを必要とする人がいるとは思えず、せっかく購入しても期待外れな結果になってしまう人を少しでも減らしたいので注意喚起としてレビューを残す。
せめて安定した動画の保存と、設定画面が無反応のようなしょうもないバグが無くなれば。

### 1/5 — タメソフト

*2024-11-17, version 1.2.4*

お金だけ取られてサポートもへったくれもなく
データも保存出来ずドラレコにも使えない
お金を捨てるソフトなのでかうのはやめましょう

### 3/5 — アプリ落ちと各種設定使えない

*2024-09-27, version 1.2.4*

先日から動画リスト開くと

一度アプリ削除した。保存画像は
消えます。
それといつからか各種設定が
反応しない。

### 1/5 — 録画記録が見れなくなった

*2024-09-22, version 1.2.4*

見ようとするとアプリが落ちる。早くどうにかして下さい。

### 2/5 — アプリ落ちる

*2024-09-05, version 1.2.4*

昨日まで普通に使えてたのに
いきなり　動画リスト開くと
アプリが落ちます😭

### 5/5 — 動画の再生できなくなった

*2024-08-12, version 1.2.1*

落ちる。改善お願い致します。

### 5/5 — 使いやすい

*2024-08-05, version 1.2.1*
