# Stack vs Phaze

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.

Both are free to download. Stack sells 1 one-off in-app purchase and Phaze sells 6 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

Phaze holds the better App Store score, 4.2 against 3.0. That said, the two scores are not equally well evidenced: Phaze has 38 ratings behind it against 2, so its average is the more settled of the two.

Stack ships an update monthly, Phaze every 3 weeks. Both last shipped on November 2, 2026.
