Verdict

The call

The clearest difference is in-app purchases: Safewave at none against HeartStamp's 1. Safewave also leads on device support (3 vs 1) and iOS requirement (15.1 vs 18.0). HeartStamp's advantage is ads (none vs shown) and update cadence (weekly vs every 2 months). On price there is nothing between them.
