# NihonDojo.ai vs Okami Dojo

NihonDojo.ai and Okami Dojo 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. NihonDojo.ai sells 4 in-app purchases, starting at $6.49 per month and Okami Dojo sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
