Verdict

The call

The clearest difference is review sentiment: PocketChem at 100% against Periodic Table's 41%. PocketChem also leads on update cadence (every 2 months vs every 9 months) and ratings volume (13 vs 1). Periodic Table's advantage is rating (5.0 vs 4.6). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Periodic Table holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: PocketChem has 13 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 41% of Periodic Table's written reviews are positive against 100% of PocketChem's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Periodic Table ships an update every 9 months, PocketChem every 2 months. The most recent releases landed on October 19, 2026 and October 23, 2026 respectively.
