# Wall Timer vs HD Scan

The clearest difference is device support: Wall Timer at 3 against HD Scan's 1. Wall Timer also leads on iOS requirement (10.0 vs 16.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
