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.
View real-time video streams from endoscope devices on your iPhone or iPad. Inspect industrial pipes, capture photos, and record videos for convenient maintenance and comparison.
