# uHoo vs Molekule

The clearest difference is rating: Molekule at 4.4 against uHoo's 2.4. Molekule also leads on in-app purchases (none vs 2) and ratings volume (11K vs 37). uHoo's advantage is update cadence (every 2 weeks vs every 2 months) and review sentiment (31% vs 17%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. uHoo sells 2 in-app purchases, starting at $7.99 per month. Molekule asks for nothing beyond the download.

Molekule holds the better App Store score, 4.4 against 2.4. That said, the two scores are not equally well evidenced: Molekule has 11K ratings behind it against 37, so its average is the more settled of the two. Written reviews complicate that: 31% of uHoo's written reviews are positive against 17% of Molekule's, so the app with the better star average is not the one people write more warmly about.

uHoo ships an update every 2 weeks, Molekule every 2 months. Both last shipped on September 24, 2026.
