# Project vs Cytus II

The clearest difference is price: Project at Free against Cytus II's $1.99. Cytus II's advantage is ads (none vs shown) and rating (4.8 vs 4.6). On review sentiment, update cadence, in-app purchases and monetization model there is nothing between them.

Project is free to download; Cytus II costs $1.99 up front. Project sells 18 one-off in-app purchases and Cytus II sells 16 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Cytus II holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Cytus II has 9.4K ratings behind it against 1.5K, so its average is the more settled of the two. Written reviews split almost evenly too, at 72% and 73% positive.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on October 26, 2026 and October 27, 2026 respectively.
