This application transforms your smartphone into a digital tachometer using its flashlight. It measures the rotational speed (RPM) of objects by flashing light at them, making them appear stationary when the flash rate matches their speed. Save readings and use it for mechanics, education, or industrial checks.
Transform your iPhone into a powerful strobe light and tachometer. Precisely control flashing speeds from 1Hz to 130Hz to measure the RPM of rotating objects by making them appear stationary. Ideal for precise speed measurements in dark environments.
This app uses slow-motion video to create a strobe light effect, allowing you to measure rotational speeds. It records video with detailed information like frame rate and exposure, and offers customizable text overlays.
