Gravity Meter: g Acceleration

Measure local gravitational acceleration with 4-decimal precision. Pendulum mode, location comparison, and STEM education features.

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.
