# Relativistic Space vs RandleSimulation

The clearest difference is update cadence: RandleSimulation at every 4 days against Relativistic Space's every 75 months. RandleSimulation also leads on iOS requirement (11.0 vs 13.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Relativistic Space ships an update every 75 months, RandleSimulation every 4 days. The most recent releases landed on June 1, 2026 and September 9, 2026 respectively.
