Verdict

The call

The clearest difference is review sentiment: Gentler Streak Workout Tracker at 70% against Pillow's 42%. Gentler Streak Workout Tracker also leads on rating (4.7 vs 4.4). Pillow's advantage is ratings volume (96K vs 8.8K) and chart position (#168 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.
