# Supernova vs AI Training Simulator

The clearest difference is ads: Supernova at none against AI Training Simulator's shown. Supernova also leads on device support (5 vs 3). AI Training Simulator's advantage is iOS requirement (15.0 vs 17.0). On price, update cadence and in-app purchases there is nothing between them.

Both are free to download. Supernova sells 10 one-off in-app purchases and AI Training Simulator sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 2 days. The most recent releases landed on October 17, 2026 and October 7, 2026 respectively.
