# AR Ruler ONE vs QuantumReader

The clearest difference is iOS requirement: AR Ruler ONE at 11.0 against QuantumReader's 16.6. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. AR Ruler ONE sells 1 one-off in-app purchase and QuantumReader sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
