Verdict
The clearest difference is update cadence: Organic Reactions Tutor at fortnightly against Functional Groups's every 4 months. Functional Groups's advantage is ratings volume (23 vs 2) and iOS requirement (15.0 vs 17.0). On price, rating, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Functional Groups sells 1 one-off in-app purchase and Organic Reactions Tutor sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.9 for Functional Groups against 5.0 for Organic Reactions Tutor. That said, the two scores are not equally well evidenced: Functional Groups has 23 ratings behind it against 2, so its average is the more settled of the two.
Functional Groups ships an update every 4 months, Organic Reactions Tutor fortnightly. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
