Verdict
The clearest difference is rating: Phaze at 4.2 against Stack's 3.0. Phaze also leads on ratings volume (38 vs 2) and iOS requirement (13.0 vs 26.0). Stack's advantage is monetization model (free with in-app purchases vs subscription). On price, update cadence, ads and in-app purchases there is nothing between them.
