# Atomo vs Periodic Table

The clearest difference is ads: Periodic Table at none against Atomo's shown. Periodic Table also leads on update cadence (weekly vs monthly). Atomo's advantage is iOS requirement (13.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Atomo sells 1 in-app purchase, starting at $1.99 per year and Periodic Table sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Atomo ships an update monthly, Periodic Table weekly. The most recent releases landed on October 24, 2026 and October 21, 2026 respectively.
