Verdict
The clearest difference is in-app purchases: PostureCHECKER at none against reactimer's 1. PostureCHECKER also leads on ads (none vs shown) and iOS requirement (15.0 vs 18.5). reactimer's advantage is update cadence (every 4 weeks vs every 6 months). On price and device support there is nothing between them.
