# Authenticator App vs Sum

The clearest difference is iOS requirement: Sum at 13.0 against Authenticator App's 16.6. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Authenticator App sells 3 in-app purchases, starting at $5.99 per 7 days and Sum sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
