MOMAX Backup holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Portable USB · Cloud Ready has 60 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 82% of Portable USB · Cloud Ready's written reviews are positive against 18% of MOMAX Backup's, so the app with the better star average is not the one people write more warmly about.
