## What is Stillspin Strobe Tachometer?

Check the speed of a fan, drill chuck or record player with your iPhone. Aim the rear torch, sweep until the motion appears still, then see the possible RPM readings and how to check them.

For turntables, use the strobe check at 33⅓, 45 or 78 RPM. The optional camera mode counts one paper marker while your phone stays beside the platter, so you can watch the speed as you adjust.

The complete strobe is free. One purchase adds camera RPM, sound RPM, cross-checking and the continuous turntable screen. No subscription.

TORCH STROBE — INCLUDED
Sweep the flash or type a speed in RPM or Hz. Lock the setting, see the other speeds that could produce the same frozen pattern, and follow the steps to check which is real. Fan and machine presets set the marks per turn and show the available range. Save readings with names, notes and target speeds.

TURNTABLE SPEED
Choose 33⅓, 45 or 78 RPM. The strobe uses the exact nominal setting, including 100/3 for 33⅓. Time a marker's drift to estimate the difference in percent and musical cents. If the timed interval cannot resolve that difference, the app says so.

With the unlock, the camera counts a paper marker on the rotating platter. Keep the phone beside the turntable and watch the RPM, speed difference and trace while adjusting. The reading clears when the marker is lost.

CAMERA AND SOUND — IN THE UNLOCK
The optical method watches a small region around a rotating mark. The acoustic method looks for a repeating sound, using the events per turn you specify. Each shows possible readings and its limits. Compare checks the methods' candidate lists and reports when they disagree.

RECORD AND SAVE
Record an eight-second freeze clip with the flash setting and its ambiguity written on it. No audio is recorded. Share the clip yourself, or keep a named measurement and export your saved readings. The strobe, freeze recorder and saved readings are included without an unlock.

YOUR DATA STAYS ON YOUR IPHONE
No account, ads or tracking. Camera and microphone input is analysed on the device. The only saved camera recording is a freeze clip you choose to make; it is deleted when you close its screen. The developer receives none of your readings or recordings. Restore an unlock with the same Apple Account.

KNOW THE LIMITS
A frozen pattern can represent more than one speed. Camera sampling can also fold a fast signal into a slower reading. The app explains these alternatives instead of claiming every number is certain. The torch check measures command timing, not emitted light. Screen light is a separate optional fallback.

This is a hobbyist and workshop tool, not a calibrated or certified instrument. Turntable readings are not wow and flutter or rumble measurements. Do not use it for calibration, certification or safety-critical work.

Flashing light can trigger a seizure in susceptible people. Read the warning before use. A strobed machine only looks stopped: keep hands, clothing and tools away from moving parts.
