# BodySense vs Hydra

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

Both are free to download. BodySense sells 3 in-app purchases, starting at $2.99 per month and Hydra sells 6 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

BodySense ships an update every 2 days, Hydra fortnightly. The most recent releases landed on October 27, 2026 and October 30, 2026 respectively.
