# Mendeleev.me vs WoziGrow

The clearest difference is update cadence: WoziGrow at every 2 days against Mendeleev.me's every 6 weeks. WoziGrow also leads on monetization model (free with in-app purchases vs paid). Mendeleev.me's advantage is rating (4.8 vs 4.5) and iOS requirement (13.0 vs 17.3). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Mendeleev.me sells 4 one-off in-app purchases and WoziGrow sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Mendeleev.me holds the better App Store score, 4.8 against 4.5. Both are backed by a comparable volume of ratings — 24 and 11 respectively.

Mendeleev.me ships an update every 6 weeks, WoziGrow every 2 days. Both last shipped on September 10, 2026.
