About
Pendulum Lab+ turns your iPhone into a real pendulum physics experiment. Hang your phone on a string, swing it, and the accelerometer measures the period, frequency, and calculates gravitational acceleration.
Real sensor data — not a simulation. Perfect for physics classrooms and STEM education.
Key Features:
- Real-time pendulum period/frequency measurement
- Gravity (g) calculation from string length
- Live acceleration waveform graph
- Standard value comparison
- Education mode with formulas and explanations
- Multiple experiment recording and averaging
- CSV export for lab reports
The physics lab in your pocket.
