# GymBro vs Supernova

The clearest difference is in-app purchases: GymBro at none against Supernova's 10. GymBro also leads on iOS requirement (13.0 vs 17.0). Supernova's advantage is ads (none vs shown) and update cadence (every 2 days vs every 3 weeks). On price there is nothing between them.

Both are free to download. Supernova sells 10 one-off in-app purchases. GymBro asks for nothing beyond the download.

GymBro ships an update every 3 weeks, Supernova every 2 days. The most recent releases landed on October 25, 2026 and November 3, 2026 respectively.
