# Harmony Cloud Pro vs Sessionography

Harmony Cloud Pro and Sessionography both sit at 5.0 stars, but that hides the real split: 100% of Sessionography's written reviews are positive against 87% of Harmony Cloud Pro's. Sessionography also leads on device support (5 vs 3). Harmony Cloud Pro's advantage is ratings volume (65 vs 10) and iOS requirement (15.1 vs 26.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Harmony Cloud Pro sells 2 in-app purchases, starting at $5.99 per month and Sessionography sells 3 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Harmony Cloud Pro against 5.0 for Sessionography. That said, the two scores are not equally well evidenced: Harmony Cloud Pro has 65 ratings behind it against 10, so its average is the more settled of the two. Written reviews are what separate them: 87% of Harmony Cloud Pro's written reviews are positive against 100% of Sessionography's.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on October 2, 2026 and September 21, 2026 respectively.
