# PDF Scanner vs ALTtext

The clearest difference is device support: ALTtext at 4 against PDF Scanner's 2. ALTtext also leads on iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. PDF Scanner sells 4 in-app purchases, starting at $0.99 per month and ALTtext sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
