# Azure ECM vs Friedrich

The clearest difference is review sentiment: Azure ECM at 100% against Friedrich's 0%. Azure ECM also leads on device support (3 vs 1) and iOS requirement (9.0 vs 16.0). Friedrich's advantage is rating (4.6 vs 4.2) and ratings volume (53 vs 5). On price, ads, in-app purchases and monetization model there is nothing between them.

Friedrich holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Friedrich has 53 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 100% of Azure ECM's written reviews are positive against 0% of Friedrich's, so the app with the better star average is not the one people write more warmly about.

Azure ECM ships an update every 2 months, Friedrich monthly. The most recent releases landed on June 1, 2026 and September 24, 2026 respectively.
