# Heart Chart vs RADS Guide

The clearest difference is iOS requirement: RADS Guide at 16.6 against Heart Chart's 26.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Heart Chart sells 1 in-app purchase, starting at $2.99 per year and RADS Guide sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
