Strobe tachometer (RPM meter)

+ Laser Tachometer + Magnetic

Features & Capabilities

STROBE TACHOMETER lets you measure rotation speed by matching flicker frequency to the object's rotation. It includes Laser Tachometer and Magnetic Tachometer modes with high precision: Laser range 0.3 Hz (18 RPM) to 1000 Hz (60,000 RPM) with 0.01–0.0001 Hz steps; update time 1 s; 5 mW laser power. Magnetic range 0.1 Hz (6 RPM) to 45 Hz (2,700 RPM) with 0.2–2% steps; update time 2–5 s. You can adjust frequency by long-press; the display can show Hz or RPM; you can change speed with app settings and the flicker frequency can be displayed in Hz or RPM.

For speeds beyond the upper limit, you can determine the speed by measuring at a lower flicker frequency and applying a simple calculation described in the appendix. The image is sharper in low light, and the iPhone flashlight can run up to 100 Hz (6,000 RPM) while a connected flashlight supports up to 1000 Hz (60,000 RPM). Overheating may cause the iPhone flashlight to turn off automatically.

Doesn’t seem to use the full brightness of the iPhone, even with the paid features unlocked and the higher brightness setting on. Frequency doesn’t seem entirely accurate either.

This was exactly the app I was looking for to create a strobe light effect to set up my turntable. The free version is actually fine, but I liked it enough that I felt I should pay for it. All the other strobe apps I tried were awful in comparison.

I use the iphone flashlight but there is an inconsistent RPM where the flicker will stop for every second and then flash a steady light
