# AZ vs GH

The clearest difference is iOS requirement: AZ at 15.1 against GH's 18.6. On price, rating, ratings volume and ads there is nothing between them.

Both are free to download. AZ sells 3 in-app purchases, starting at $5.99 per month and GH sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for AZ against 5.0 for GH. Both are backed by a comparable volume of ratings — 1 and 1 respectively.
