Verdict
The clearest difference is in-app purchases: Ding Dong Doorbell at none against Contraction Timer's 1. Ding Dong Doorbell also leads on iOS requirement (12.0 vs 17.0). Contraction Timer's advantage is update cadence (every 3 weeks vs every 2 months). On price, ads and device support there is nothing between them.
