Verdict
The clearest difference is review sentiment: Functional Groups at 100% against Chem AI's 20%. Functional Groups also leads on monetization model (free with in-app purchases vs subscription) and rating (4.9 vs 4.4). Chem AI's advantage is update cadence (fortnightly vs every 4 months) and ratings volume (818 vs 21). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Functional Groups sells 1 one-off in-app purchase and Chem AI sells 15 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Functional Groups holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: Chem AI has 818 ratings behind it against 21, so its average is the more settled of the two. Written reviews point the same way: 100% of Functional Groups's written reviews are positive against 20% of Chem AI's.
Functional Groups ships an update every 4 months, Chem AI fortnightly. Both last shipped on September 13, 2026.
