# Ninja vs DOOS

The clearest difference is ratings volume: Ninja at 88K against DOOS's 328. Ninja also leads on review sentiment (66% vs 55%). DOOS's advantage is iOS requirement (15.6 vs 17.0). On price, rating, update cadence and ads there is nothing between them.

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

On the App Store both sit at effectively the same score — 4.6 for Ninja against 4.7 for DOOS. That said, the two scores are not equally well evidenced: Ninja has 88K ratings behind it against 328, so its average is the more settled of the two. Written reviews are what separate them: 66% of Ninja's written reviews are positive against 55% of DOOS's.
