Impact Force Meter is a handy app for recording and playing back the results of a direct impact test.

Note: This app uses an accelerometer sensor instead of a gyroscope. It's recommended that you use a device with an accelerometer sensor (such as a mobile phone) to get the most accurate results.

Impact Force Meter is used to record and playback the results of a direct impact test. You can set the weight of the punching bag to which you have attached the smartphone. The app will then multiply the weight by the acceleration and display the results in newtons and kg/cm.
