## Description

Track every rotation with precision. Real-time spin counter with direction detection, gyroscope-powered chart, and CSV export — all in one tap.

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.
