Verdict
The clearest difference is review sentiment: Physiology Solution at 67% against Chem AI's 20%. Physiology Solution also leads on in-app purchases (none vs 16) and ads (none vs shown). Chem AI's advantage is rating (4.4 vs 3.8) and update cadence (fortnightly vs every 7 months). On price and device support 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. Chem AI sells 15 in-app purchases, starting at $0.99 per 7 days. Physiology Solution asks for nothing beyond the download.
Chem AI holds the better App Store score, 4.4 against 3.8. That said, the two scores are not equally well evidenced: Chem AI has 823 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 67% of Physiology Solution's written reviews are positive against 20% of Chem AI's, so the app with the better star average is not the one people write more warmly about.
Physiology Solution ships an update every 7 months, Chem AI fortnightly. The most recent releases landed on October 10, 2026 and October 30, 2026 respectively.
