# Force of Gravity vs Solar System Sim

The clearest difference is in-app purchases: Force of Gravity at none against Solar System Sim's 5. Force of Gravity also leads on ads (none vs shown) and update cadence (daily vs every 5 days). Solar System Sim's advantage is ratings volume (4.4K vs 2) and device support (3 vs 1). On price and rating there is nothing between them.

Both are free to download. Solar System Sim sells 5 one-off in-app purchases. Force of Gravity asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.5 for Force of Gravity against 4.5 for Solar System Sim. That said, the two scores are not equally well evidenced: Solar System Sim has 4.4K ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 100% of Force of Gravity's written reviews are positive against 81% of Solar System Sim's.

Force of Gravity ships an update daily, Solar System Sim every 5 days. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
