# Timer vs Sanity Scan

The clearest difference is iOS requirement: Timer at 15.0 against Sanity Scan's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Timer sells 1 in-app purchase, starting at $0.99 per month and Sanity Scan sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
