# Biology Helper vs StudyRank

The clearest difference is iOS requirement: Biology Helper at 13.0 against StudyRank's 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Biology Helper sells 2 in-app purchases, starting at $4.99 per 7 days and StudyRank sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
