Barefoot Blender is for trained divers and fill operators only. It is not a substitute for formal training, agency procedures, shop policy, or calibrated gas analysis. Always verify final oxygen and helium content with calibrated analyzers before diving or labeling cylinders. Incorrect gas blending can cause serious injury or death. Subscription.

Verdict
The clearest difference is in-app purchases: MyFathom at none against Barefoot Blender's 1. MyFathom also leads on iOS requirement (11.0 vs 15.0). Barefoot Blender's advantage is update cadence (monthly vs every 13 months). On price, ads and device support there is nothing between them.
