# Mendeleev.me vs AI

The clearest difference is in-app purchases: AI at none against Mendeleev.me's 4. Mendeleev.me's advantage is update cadence (every 6 weeks vs every 4 months) and iOS requirement (13.0 vs 15.0). On price, ads and device support there is nothing between them.

Both are free to download. Mendeleev.me sells 4 one-off in-app purchases. AI asks for nothing beyond the download.

Mendeleev.me ships an update every 6 weeks, AI every 4 months. The most recent releases landed on October 14, 2026 and October 10, 2026 respectively.
