# Force of Gravity vs Space Crash Simulator

The clearest difference is in-app purchases: Force of Gravity at none against Space Crash Simulator's 1. Force of Gravity also leads on ads (none vs shown) and update cadence (daily vs every 5 days). Space Crash Simulator's advantage is ratings volume (801 vs 2) and device support (3 vs 1). On price and rating there is nothing between them.

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