# phyphox vs quantum error correction

The clearest difference is iOS requirement: phyphox at 12.0 against quantum error correction's 16.0. On price, ads, in-app purchases and device support there is nothing between them.

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