# Juno vs Gravity Physics

The clearest difference is in-app purchases: Gravity Physics at none against Juno's 4. Gravity Physics also leads on ads (none vs shown) and update cadence (weekly vs monthly). Juno's advantage is iOS requirement (14.0 vs 17.6). On price and device support there is nothing between them.

Both are free to download. Juno sells 4 one-off in-app purchases. Gravity Physics asks for nothing beyond the download.

Juno ships an update monthly, Gravity Physics weekly. The most recent releases landed on October 23, 2026 and October 6, 2026 respectively.
