Verdict
The clearest difference is in-app purchases: iFertracker at none against Wrist Temperature Tracker's 3. iFertracker also leads on review sentiment (40% vs 28%) and iOS requirement (10.0 vs 18.0). Wrist Temperature Tracker's advantage is rating (3.4 vs 3.1) and update cadence (every 11 days vs every 2 months). On price, ratings volume, ads and device support there is nothing between them.
