# Rheem vs Azure ECM

The clearest difference is review sentiment: Azure ECM at 100% against Rheem's 40%. Azure ECM also leads on device support (3 vs 1) and iOS requirement (9.0 vs 16.0). Rheem's advantage is rating (4.6 vs 3.5) and ratings volume (1.8K vs 8). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Rheem holds the better App Store score, 4.6 against 3.5. That said, the two scores are not equally well evidenced: Rheem has 1.8K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 40% of Rheem's written reviews are positive against 100% of Azure ECM's, so the app with the better star average is not the one people write more warmly about.

Rheem ships an update monthly, Azure ECM every 2 months. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
