gravity detector vs MARVLS
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
gravity detector
Measure the G-force experienced in elevators or planes and compare it to planetary gravity. Record environmental photos, videos, and coordinates to save for later reference, and view G-values on a map.
- Measure G-force in real-time
- Compare G-force to planetary gravity
- Record environmental photos and videos
- Save location coordinates
- View G-values on a map

While on an elevator or plane. You can check the G value you're experiencing, and see which planet's gravity is it equivalent to. Even more, you can measure the earth gravity around your place, take photo/video of the environment, record the coordinate, and save it for future reference. And you can check the G values in map. Note: Please use this app only inside Earth. And the G value is approximate.
MARVLS
