# HUUM vs COZZIA

HUUM and COZZIA both sit at 2.3 stars, but that hides the real split: 50% of COZZIA's written reviews are positive against 11% of HUUM's. COZZIA also leads on iOS requirement (12 vs 16.4). HUUM's advantage is ratings volume (30 vs 7). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

HUUM holds the better App Store score, 2.3 against 2.1. Both are backed by a comparable volume of ratings — 30 and 7 respectively. Written reviews complicate that: 11% of HUUM's written reviews are positive against 50% of COZZIA's, so the app with the better star average is not the one people write more warmly about.

HUUM ships an update monthly, COZZIA every 6 weeks. The most recent releases landed on November 1, 2026 and October 31, 2026 respectively.
