Verdict
The clearest difference is review sentiment: When at 90% against Time Master's 33%. When also leads on rating (4.7 vs 2.3) and ratings volume (28 vs 3). Time Master's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence, in-app purchases and device support there is nothing between them.
