Before using this app you must enter your body height(in settings).
To start measuring the speed there are 3 steps you need to make:
- point the camera to the starting point of the interval you want to measure(point to the ground like in the last image) and click the orange button
- point the camera to the ending point of the interval(like in the last picture) and click the button again
- now turn the phone with camera pointing the moving subject starting before the first point and ending after the second point(the top bar shows the progress)
Click again the button to reset.
In the short future I will put updates to resolve bugs and support more screen dimensions and a priced version with instant speed and more features like cam recording.
Note! This app is a real speed gun based on mathematical calculations but limited to the quality of your phone''s sensors.
Please calibrate your compass if you have trouble with the speed gun and send me messages every time you encounter bugs or problems. Thank you!
