Verdict
The clearest difference is price: Scatter ADHD at Free against wristSkinTemperature's $0.99. Scatter ADHD also leads on update cadence (every 5 days vs fortnightly). wristSkinTemperature's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On ads and in-app purchases there is nothing between them.
