# Periodic Table vs Russian Verb Conjugations

The clearest difference is iOS requirement: Russian Verb Conjugations at 15.0 against Periodic Table's 17.0. On price, ads, 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 Russian Verb Conjugations sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
