Verdict
The clearest difference is review sentiment: One at 100% against Timer Machine's 50%. One also leads on rating (5.0 vs 3.8) and iOS requirement (12.0 vs 15.0). Timer Machine's advantage is update cadence (every 5 months vs every 23 months) and ratings volume (20 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.
