This app transforms your iPhone into a strobe light and a tachometer. You can control the flashing speed of your phone's flashlight from 1Hz to 130Hz. This allows you to measure the rotational speed (RPM) of objects by making them appear stationary when viewed under the flashing light.
In a dark environment, turn on the object you want to measure (e.g., a fan). Launch the app and manually adjust the strobe speed using the main slider until the object appears almost still. Then, use the fine-tuning buttons for exact speed adjustment. The app will display the speed in both Hz and RPM.
