## Description

Turn your iPhone into a precision stroboscope. Adjust frequency from 0.5-100Hz, control duty cycle, find harmonics, and measure RPM — all in one powerful tool.

Professional strobe light for inspecting rotating machinery, measuring RPM, and freezing motion. Adjust frequency from 0.5–100 Hz with precision control — perfect for mechanics, engineers, and creators.

FEATURES:
• Adjustable frequency range from 0.5 Hz to 100 Hz
• Three duty cycle modes: 10%, 25%, and 50%
• ×2 and ÷2 buttons for quick harmonic frequency finding
• RPM presets for common motor and fan speeds
• Real-time display of period, timing, and flashes per minute
• Clean, intuitive interface designed for fieldwork

APPLICATIONS:
• Inspect rotating machinery and motors
• Measure fan blade and propeller RPM
• Freeze apparent motion for visual inspection
• Verify belt and gear synchronization
• Educational physics demonstrations
