# Heart Graph vs Pulse Notes

The clearest difference is iOS requirement: Heart Graph at 17.0 against Pulse Notes's 27.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Heart Graph sells 2 one-off in-app purchases and Pulse Notes sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
