How it works: With Camera: First, mark the edge of the machine whose rotational speed you want to find. Please make sure that the machine is properly visible in the camera preview. Now, go to the app, open camera RPM and adjust the RPM using the plus, minus buttons or seek bar on the screen. Now adjust the RPM unless the rotating machine becomes stationary in the camera preview. Read the value from the input field; this is the RPM of your rotating machine.
