Verdict
The clearest difference is price: Temp Tracker at Free against Simple Scales's $0.99. Temp Tracker also leads on rating (5.0 vs 3.9) and iOS requirement (16.6 vs 26.6). Simple Scales's advantage is ratings volume (515 vs 1) and update cadence (every 6 months vs every 17 months). On ads, in-app purchases and monetization model there is nothing between them.
