# Cytus vs Project

The clearest difference is price: Project at Free against Cytus's $1.99. Project also leads on update cadence (monthly vs every 4 months). Cytus's advantage is ads (none vs shown) and rating (4.9 vs 4.6). On ratings volume, in-app purchases, monetization model and device support there is nothing between them.

Project is free to download; Cytus costs $1.99 up front. Cytus sells 10 one-off in-app purchases and Project sells 18 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
