Gravity Sensor: G-Force Meter

Turn your smartphone into an accelerometer. Gravity Sensor uses your phone's built-in sensors to measure gravity and G-force in real time — completely free. Readings are plotted on a clear, easy-to-read graph, and the maximum value (MAX) is recorded automatically. From science class to roller coasters, make the invisible forces around you visible. ■ Perfect for ・Science class & experiments: observe standard gravity (1 G) and learn about force and motion ・School projects: drop your phone (onto a cushion — safely!) and watch the reading fall to 0 G in free fall ・Elevators: measure how G changes as you go up and down ・Roller coasters & rides: see the G-forces you feel as real numbers ・Trains & cars: observe acceleration, braking, and vibration ■ Features ・Real-time gravity / G-force measurement ・Live graph of your readings ・Automatic MAX value recording ・One-tap start and stop — no setup required ・Simple, lightweight, and fast ■ How to use Open the app Tap START That's it — watch the graph respond as you move At rest, the reading shows about 1.0 G (Earth's gravity). Try moving your phone, riding an elevator, or taking it on a ride and see how the numbers change. ■ Notes ・Measurement accuracy depends on the sensor built into your device ・Readings are intended for educational and entertainment purposes For curious kids, science teachers, and anyone who's ever wondered "how many Gs was that?" — download now and start measuring the forces around you!
