🧪 Gravity Lab — Support
A pocket physics playground for ages 8–12: tilt your device to roll a marble through mazes while gravity switches between Earth, the Moon and Jupiter.
How to play
- Tilt the phone or iPad to steer the marble to the checkered flag 🏁.
- Avoid the dark holes — fall in and the marble pops back to the start.
- Finish fast with no wall bumps for 3 stars; stars earn coins for marble skins.
- Watch the gravity badge: the Moon makes the marble floaty, Jupiter makes it heavy and fast. Ice floors are slippery; sand floors grip.
- Every finished level shows a Lab Note — a one-line real science fact.
FAQ
Tilting doesn't work?Gravity Lab uses the built-in motion sensor. If you prefer, turn on "Finger steering" in the app's Settings tab (⚙️) to steer by dragging on the maze instead.
How do I reset all progress?Open Settings (⚙️) and press-and-hold "Empty the lab" for 2 seconds. The long hold is deliberate so progress can't be wiped by accident.
Are there ads or purchases?No. Gravity Lab has no ads, no in-app purchases, no tracking, and works fully offline. Coins are earned only by playing. See the
privacy policy.
Which devices are supported?iPhone and iPad running iOS 17 or later.
