# Fitness AI vs Flow

The clearest difference is ads: Flow at none against Fitness AI's shown. Flow also leads on update cadence (every 2 days vs every 4 days). Fitness AI's advantage is device support (3 vs 1) and iOS requirement (15.6 vs 26.0). On price and in-app purchases there is nothing between them.

Both are free to download. Fitness AI sells 1 one-off in-app purchase and Flow sells 3 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Fitness AI ships an update every 4 days, Flow every 2 days. The most recent releases landed on October 7, 2026 and September 25, 2026 respectively.
