### 5/5 — すごい良い

*2026-01-12*

シグナルの使い方がわかりやすく、シンプルで良いです。あと、色がもっとはっきりするといいと思います。

### 5/5 — ミニ四駆用に良いです

*2025-02-13*

ミニ四駆などでスタートの合図を人がやるとバラツキが出るので、アプリを探しておりました。欲を言えば、公式大会のようにカウントせずに赤→青と切り替わる方式(時間ランダム)の方が大会の練習にもなって良いと思いますので、ぜひ機能追加をご検討ください

### 5/5 — 便利そうです

*2023-08-05*

このアプリ地味に役立ちそうですが、f1のスタートみたいにスタートの瞬間のタイミングをいじることができれば更に便利になると思います、ご検討お願いします
