# BBnotes vs DiffMind

The clearest difference is iOS requirement: DiffMind at 15.0 against BBnotes's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. BBnotes sells 8 in-app purchases, starting at $8.99 per month and DiffMind sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
