# PhysioAI vs Instagym

The clearest difference is update cadence: Instagym at every 6 days against PhysioAI's fortnightly. PhysioAI's advantage is iOS requirement (12.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PhysioAI sells 10 in-app purchases, starting at $6.99 per 7 days and Instagym sells 9 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PhysioAI ships an update fortnightly, Instagym every 6 days. The most recent releases landed on September 27, 2026 and October 3, 2026 respectively.
