Verdict

The call

The clearest difference is monetization model: Phase at free against Workout Log's freemium. Phase also leads on ratings volume (4 vs 1). Workout Log's advantage is update cadence (every 10 days vs every 5 weeks) and iOS requirement (15.1 vs 17.0). On price, rating, ads and in-app purchases there is nothing between them.
