# Planet simulation vs Gravity Switch

The clearest difference is in-app purchases: Planet simulation at none against Gravity Switch's 7. Planet simulation also leads on review sentiment (74% vs 64%). Gravity Switch's advantage is ads (none vs shown) and update cadence (every 5 days vs every 8 months). On price and device support there is nothing between them.

Both are free to download. Gravity Switch sells 7 one-off in-app purchases. Planet simulation asks for nothing beyond the download.

Gravity Switch holds the better App Store score, 4.2 against 3.9. That said, the two scores are not equally well evidenced: Gravity Switch has 1.4K ratings behind it against 165, so its average is the more settled of the two. Written reviews complicate that: 74% of Planet simulation's written reviews are positive against 64% of Gravity Switch's, so the app with the better star average is not the one people write more warmly about.

Planet simulation ships an update every 8 months, Gravity Switch every 5 days. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
