# DEEMO vs Chess Music

The clearest difference is in-app purchases: Chess Music at none against DEEMO's 10. Chess Music also leads on update cadence (every 4 days vs every 2 months) and review sentiment (100% vs 91%). DEEMO's advantage is ratings volume (5.1K vs 3) and chart position (#13 vs #138). On price, rating, ads and device support there is nothing between them.

DEEMO costs $1.99 and Chess Music $1.99 up front. DEEMO sells 10 one-off in-app purchases. Chess Music asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for DEEMO against 5.0 for Chess Music. That said, the two scores are not equally well evidenced: DEEMO has 5.1K ratings behind it against 3, so its average is the more settled of the two. Written reviews are what separate them: 91% of DEEMO's written reviews are positive against 100% of Chess Music's.

DEEMO ships an update every 2 months, Chess Music every 4 days. The most recent releases landed on October 15, 2026 and September 30, 2026 respectively.
