ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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