# QR Barcode Scanner Reader vs Signal

QR Barcode Scanner Reader and Signal are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. QR Barcode Scanner Reader sells 3 in-app purchases, starting at $4.99 per month and Signal sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
