# 66 Days vs Desk Dojo

Desk Dojo also leads on iOS requirement (15.1 vs 17.0). 66 Days's advantage is ads (none vs shown) and ratings volume (259 vs 20).

Both are free to download. 66 Days sells 2 in-app purchases, starting at $15.99 per month and Desk Dojo sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: 66 Days has 259 ratings behind it against 20, so its average is the more settled of the two.
