About this app
Rotation Count turns your iPhone into a precise spin tracker. Using your device's gyroscope, it counts every rotation in real time — perfect for testing motors, tracking exercise reps, measuring drill turns, or any task where revolutions matter. Tap Start, place your phone on the rotating object (or attach it for full revolutions), and watch the counter move. The live chart visualizes angular velocity, while direction detection tells you clockwise from counter-clockwise. Key Features: - Real-time rotation counting with gyroscope - Direction detection (CW/CCW) - Live angular velocity chart - Min, max, and average tracking - Session timer and elapsed display - CSV data export for full sessions - Min/max/average and sample-rate display - Clean, intuitive dark interface Perfect for hobbyists testing fan speeds, mechanics measuring drill RPM, fitness fans counting bike crank revolutions, or engineers diagnosing motor performance. Know exactly how fast — and which way — anything spins.

What’s New
Ads no longer interrupt you mid-task. Anything full-screen now waits until you have finished what you were doing, and the app stops showing a blank pause where an ad failed to load.

Ratings growth
Baseline captured. Growth appears after the crawler observes a changed rating count.
Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
