# Space Crash Simulator vs Gravity Physics

The clearest difference is in-app purchases: Gravity Physics at none against Space Crash Simulator's 1. Gravity Physics also leads on ads (none vs shown). Space Crash Simulator's advantage is iOS requirement (15.0 vs 17.6). On price, update cadence and device support there is nothing between them.

Both are free to download. Space Crash Simulator sells 1 one-off in-app purchase. Gravity Physics asks for nothing beyond the download.

Space Crash Simulator ships an update every 5 days, Gravity Physics weekly. The most recent releases landed on October 14, 2026 and October 6, 2026 respectively.
