# PhysioAI vs Probell

The clearest difference is update cadence: Probell at every 3 days against PhysioAI's fortnightly. PhysioAI's advantage is iOS requirement (12.0 vs 15.0). 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 Probell sells 9 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

PhysioAI ships an update fortnightly, Probell every 3 days. The most recent releases landed on September 27, 2026 and September 10, 2026 respectively.
