RPM Meter: Stroboscope para Android

RPM Meter: Stroboscope is a productivity application designed for Android that enables contactless RPM measurement, catering specifically to maintenance and calibration tasks. It utilizes the stroboscopic principle to achieve motion measurement through LED pulses or camera frame sampling. This allows users to visualize steady freezes of rotating parts, read RPM values directly on-screen, and adjust readings using harmonic controls. Essential features include a harmonic helper for managing multiple speeds, unit conversion between RPM and Hz, and calculators for gear ratios and surface speed, making it suitable for mechanics, technicians, and hobbyists alike.

The application supports both strobe and camera modes for effective measurement in various lighting conditions, relying on standard smartphone hardware. It also enables quick calculations and recordkeeping without the need for internet access, thus enhancing privacy. Users can manually adjust camera settings to optimize measurements under different lighting. However, the app's performance is contingent on the capabilities of the device's hardware, particularly the LED flash and camera frame rate, which can limit its effectiveness for high-speed diagnostics.
