# Chaos Lab vs Magnetic Pendulum

The clearest difference is rating: Chaos Lab at 4.9 against Magnetic Pendulum's 4.0. Chaos Lab also leads on update cadence (every 3 days vs every 56 months). Magnetic Pendulum's advantage is review sentiment (100% vs 69%) and iOS requirement (15.2 vs 18.0). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Chaos Lab holds the better App Store score, 4.9 against 4.0. Both are backed by a comparable volume of ratings — 7 and 3 respectively. Written reviews complicate that: 69% of Chaos Lab's written reviews are positive against 100% of Magnetic Pendulum's, so the app with the better star average is not the one people write more warmly about.

Chaos Lab ships an update every 3 days, Magnetic Pendulum every 56 months. The most recent releases landed on October 1, 2026 and October 10, 2026 respectively.
