# Periodic Table vs Kimiya

The clearest difference is update cadence: Kimiya at every 3 days against Periodic Table's every 11 days. Periodic Table's advantage is device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Periodic Table sells 2 one-off in-app purchases and Kimiya sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Periodic Table ships an update every 11 days, Kimiya every 3 days. The most recent releases landed on October 1, 2026 and October 9, 2026 respectively.
