# ki vs Ninja Tobu

The clearest difference is rating: Ninja Tobu at 4.1 against ki's 3.0. Ninja Tobu also leads on review sentiment (65% vs 26%) and update cadence (every 3 weeks vs every 4 months). ki's advantage is ads (none vs shown) and iOS requirement (8.0 vs 15.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. ki sells 3 one-off in-app purchases and Ninja Tobu sells 14 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: Ninja Tobu has 260 ratings behind it against 30, so its average is the more settled of the two.
