## What is Gravity Meter?

Gravity Meter+ precisely measures the local gravitational acceleration (g) using your iPhone's motion sensors. Compare your reading against the standard value of 9.80665 m/s² and see how gravity varies by location.

Includes a pendulum experiment mode for physics education and a location-based gravity comparison feature.

Key Features:
- Precise g-value display (4 decimal places)
- World average comparison with deviation %
- Location-based gravity recording (GPS + altitude)
- Pendulum experiment mode
- Altitude vs gravity relationship graph
- Education mode with gravity explanations
- Multi-experiment averaging

Perfect for physics education, science experiments, and curious minds.
