Want to measure the G-load when your flight is taking off? Try this interesting tool. It shows motion data(GPS speed, 3-axis acceleration and total acceleration) on your Android screen. As mobile phone sensors are cheap and not so accurate, DO NOT use it for anything that matters.
The displayed motion data are(from top screen to bottom):
- GPS speed
- Horizontal acceleration
- Side acceleration
- Vertical acceleration(G-Load)
- Total acceleration
