# Red Sheet vs Sengata Dojo

The clearest difference is ads: Sengata Dojo at none against Red Sheet's shown. Red Sheet's advantage is device support (4 vs 2) and iOS requirement (13.0 vs 18.0). On price and in-app purchases there is nothing between them.

Both are free to download. Red Sheet sells 7 in-app purchases, starting at $2.99 per month and Sengata Dojo sells 2 in-app purchases, starting at $5.00 per month. Whichever you choose, the download price is not the number that matters.
