First and only 3D-graphical Vector Accelerometer in App Store: Smoothly visualize and measure the current acceleration. It can be used on earth, on moon or in orbit (where relative would be equal to absolute mode - please prove) to visualize the direction and strength of the gravitation - or simply at home to measure the g-forces you reach while shaking your phone - however be warned if you tend to get to the limits! :-). A fun application is to place the iPhone/iPod steady in your car (or any other moving vehicle), go to relative mode, zero it once when you are standing and then see the current g-forces in effect while you drive (e.g. what g-force does your car get when you accelerate?).

The application has five different display modes for acceleration visualization:

- Absolute Mode: Displays the reverse acceleration of the iPhone (1g up when hold steady).

- X-Rotation - Y-Rotation - Z-Rotation: The arrow will display the rotation around the X-, Y- and Z-Axis of the iPhone. The digital indicator shows the angle numerically (-180° - +180°). A way to calibrate will be added with one of the next updates, so you could use this as a level.

- Relative Mode: This mode shows the relative strength (absolute minus compensation vector) of the acceleration.

For a detailed documentation, please visit our product homepage.

For recreational use only. However it CAN (!) be very accurate. The measurement is performed as good as possible (we try our best) by using the inbuilt accelerometer and magnetometer to their limits. The range of the accelerometer typically has a max of ±3g (~4.2g displayed here if combined). However, tell us your experience!

My teacher (kwetee wetee) recommended this app and it was fun! I thoroughly enjoyed the app and but it wasn't precise

Erg glitchy ,

Good but confusing

I have an iPhone 5s, and I tested this app by walking around a room while increasing and decreasing my speed. It did not work as expected because I expected it to be easier to use. It would have been a lot better if there was a tutorial or instructions.

Good But Confusing

The app gave me my acceleration, but it was not clear with how to find your acceleration using the app. This app is good if you know how to use it, but I didn’t and could not find any directions. I had to get help just to find out how to see my acceleration. Not beginner friendly.
