### 2/5 — ありえない球速表示と多発するエラー

*2026-08-11*

投げる人の位置や距離を合わせるのに時間がかかるし、ようやく計測できると思ったらエラーで計測できない...
10回に1回くらいのペースで球速とかフォームが表示されるけど、軽く投げているのに156キロって出たりしてもう笑っちゃいました。

### 3/5 — 全部エラー

*2026-07-27*

友達と球速を測りたいとこのアプリを入れました、ですが10回やって全部エラー、まあ測れた時はとてもいいと思います、フォーム確認とか、

まあスマホのアプリで無料なので文句言えないしまあそれなら普通のスピードガン買えって言う話なんですけどね、

### 1/5 — Terrified

*2026-07-11, version 1.7*

The thing said I throw 30 mph after that I got a radar gun and said I threw 59 mph your is totally trash

### 3/5 — Solo

*2026-06-24, version 1.7*

I think it is good but it limits solo pitching

### 1/5 — It is not good

*2026-06-16, version 1.7*

It will not track my through and we are doing all the steps right

### 1/5 — why?

*2026-05-27, version 1.7*

this doesn’t detect your speed at all, it never detects the ball, no matter where it’s at, i tried different angles, with and without a glove multiple times, and it still didn’t work,it has lots of ads and i will never recommend!

### 1/5 — あ

*2026-05-26, version 1.7*

球速が適当

### 5/5 — サッカー⚽️でも測れる

*2026-05-24, version 1.7*

とても役に立つからサッカー用も作って欲しい

### 4/5 — Pretty good

*2026-05-18, version 1.7*

Good app but sometimes hard to get the pitcher in the boarder but really fun when you do also can’t really do it by yourself

### 4/5 — Interest

*2026-05-13*

Is there a specific mesurment for the object that is always must be baseball, or it can be registrated as a different flying ball (basketball, handball, waterpolo)?
