## What is Gravity Labs?

The device itself is the lab instrument! Gravity Lab turns your iPhone or iPad into a pocket physics playground for young scientists aged 8–12.

TILT TO EXPERIMENT
Steer a marble through 8 hand-crafted mazes just by tilting the device. Dodge the holes, find the gaps, reach the flag — and feel how real physics behaves while you do it.

FEEL THREE GRAVITIES
• Earth — the world you know
• Moon — 1/6 gravity, the marble floats like an astronaut
• Jupiter — 2.4× gravity, heavy and fast!
Some levels even switch gravity mid-run. Adapt, scientist!

ICE OR SAND
Slippery ice barely slows the marble; grippy sand brakes it fast. Friction stops being a textbook word the moment you feel the difference.

LEARN WITHOUT READING A TEXTBOOK
Every finished level shows a one-line Lab Note — a real science fact about what just happened. Galileo's marble experiment, why ice is slippery, how astronauts jump higher: science sneaks in one line at a time.

EARN LIKE A SCIENTIST
• 1–3 stars per level for speed and precision
• Coins to spend on marble skins (galaxy, lava, glitter)
• 6 scientist badges: Friction Finder, Gravity Guru, Momentum Master and more
• A daily lab streak for coming back to experiment

MADE FOR KIDS, TRUSTED BY PARENTS
• No ads, no in-app purchases, no tracking
• No account, no internet needed — works fully offline
• No reading required to start playing
• All progress stays on the device
• Prefer not to tilt? Finger-steering mode is in Settings

Pick up the lab. Tilt it. That's the whole instruction manual.
