Verdict
The clearest difference is in-app purchases: Rattle Toy at none against Contraction Timer & Tracker's 6. Rattle Toy also leads on ads (none vs shown) and rating (4.8 vs 4.6). Contraction Timer & Tracker's advantage is update cadence (fortnightly vs every 4 months) and ratings volume (50K vs 5). On price and device support there is nothing between them.
