## What is mAx Speed Calculator?

Description

Originally released in 2009, mAx has been enjoyed by baseball fans for over 16 years and has now been redesigned for an even better experience.

mAx is a simple ball speed calculator that estimates the speed of a ball based on the elapsed time between throwing and catching.

Using the app is easy.

Tap PUSH when the ball is thrown, then tap RELEASE when it is caught.

With its simple operation, anyone can measure ball speed anytime.

The app supports baseball, Little League, and softball, and lets you customize the throwing distance to match different playing conditions.

It’s perfect for pitching practice, youth baseball, playing catch with family, or simply challenging friends to see who can throw faster.

Because the measurement distance can be customized, mAx can also be used for other sports involving a ball, such as measuring the speed of a soccer shot.

Key Features

• Supports Baseball, Little League, and Softball

• Customizable throwing distance

• Switch between km/h and mph

• Save and edit measurement history

Before You Use

mAx is a ball speed calculator that estimates speed based on the elapsed time between throwing and catching.

It is not a radar gun and does not automatically detect the ball.

Measurement accuracy depends on the timing of your input.

The displayed speed is an average speed, so it may differ from the peak speed shown on TV broadcasts or professional radar systems.

Continuous Improvements

Since its original release in 2009, mAx has continued to evolve based on user feedback.

We will keep improving the app with new features, better usability, and enhanced accuracy.

We hope mAx helps make baseball even more fun.

## Key features

- Measures pitched ball speed
- Adjustable for baseball, little league, softball
- Input distance for custom measurements
- Supports km/h and mph units
- Simple one-touch operation

### 1/5 — 買うな

*2016-12-30*

スピードガンじゃないから、ただのストップウォッチorz

**Developer response:** ご購入いただきありがとうございます。
本アプリは説明にも記載しております通り、レーダー式のスピードガンではなく、投球時間から球速を算出する「簡易球速計」です。
説明が十分に伝わらず、誤解を招いてしまったようで申し訳ありません。
少しコツがいりますが、楽しみながらご利用いただけますと幸いです。

### 1/5 — 詐欺アプリ

*2016-03-14*

このアプリ球速を測る為に
PUSHボタンを押して離したら球速が測れると書いてありますが、投げてもいないのに150㌔以上の球速がででしっかりと測ってくれません！(💢'ω')ただ金をゴミ箱に捨てた様な気でしょうがないです(💢'ω')

**Developer response:** ご購入いただきありがとうございます。
本アプリは、投球開始から捕球までの時間を手動で計測し、球速を算出する「簡易球速計」です。スマートフォンが投球動作を認識したり、自動で球速を測定するアプリではありません。
説明が十分に伝わらず、誤解を招いてしまったようで申し訳ありません。今後もより分かりやすい説明に努めてまいります。

### 5/5 — いいです。

*2015-07-28*

少しコツがいるので、
プロよりもアマチュア野球くらいの球速の方が測りやすいですね。
手軽に測れるので、おもしろくてついつい何度も測ってしまいます。

**Developer response:** ご購入いただきありがとうございます。
楽しんでご利用いただけたようで、とても嬉しく思います。
コツが必要な点や、アマチュア野球くらいの球速が測りやすいという貴重なご感想もありがとうございます。
今後もより使いやすく、楽しんでいただけるアプリを目指して改善を続けてまいります。
