# Periodic Table vs Periodic Table..

The clearest difference is ads: Periodic Table at none against Periodic Table..'s shown. Periodic Table..'s advantage is iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

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