Verdict
The clearest difference is in-app purchases: Ankle Flex at none against HeelRaise's 1. Ankle Flex also leads on device support (3 vs 1) and iOS requirement (15.6 vs 18.6). HeelRaise's advantage is update cadence (every 2 months vs every 5 months). On price and ads there is nothing between them.
