# 320 Guide vs Once Upon a Drawing

320 Guide and Once Upon a Drawing 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. 320 Guide sells 8 in-app purchases, starting at $9.99 per month and Once Upon a Drawing sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
