# Chemistry. Periodic table. AI vs Physiology Solution

The clearest difference is rating: Chemistry. Periodic table. AI at 4.9 against Physiology Solution's 3.8. Chemistry. Periodic table. AI also leads on update cadence (fortnightly vs every 7 months) and ratings volume (2.8K vs 5). Physiology Solution's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price there is nothing between them.

Both are free to download. Chemistry. Periodic table. AI sells 7 in-app purchases, starting at $1.99 per 7 days. Physiology Solution asks for nothing beyond the download.

Chemistry. Periodic table. AI holds the better App Store score, 4.9 against 3.8. That said, the two scores are not equally well evidenced: Chemistry. Periodic table. AI has 2.8K ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 84% of Chemistry. Periodic table. AI's written reviews are positive against 67% of Physiology Solution's.

Chemistry. Periodic table. AI ships an update fortnightly, Physiology Solution every 7 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
