Verdict

The call

The clearest difference is in-app purchases: DeviceAID at none against Heart Chart's 1. DeviceAID also leads on iOS requirement (18.0 vs 26.0). Heart Chart's advantage is ads (none vs shown) and update cadence (every 3 days vs every 14 months). On price and device support there is nothing between them.
