Verdict
The clearest difference is review sentiment: My Contraction Tracker at 96% against YUNMAI's 23%. My Contraction Tracker also leads on rating (4.5 vs 2.1). YUNMAI's advantage is ratings volume (400 vs 8) and update cadence (every 3 months vs every 7 months). On price, ads, in-app purchases and device support there is nothing between them.
