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.

Verdict
The clearest difference is in-app purchases: Gravity Labs at none against Rytmos's 1. Rytmos's advantage is iOS requirement (11.0 vs 17.0). On price, ads and device support there is nothing between them.
