# Portable USB · Cloud Ready vs MOMAX Backup

The clearest difference is review sentiment: Portable USB · Cloud Ready at 82% against MOMAX Backup's 18%. Portable USB · Cloud Ready also leads on ratings volume (60 vs 2). MOMAX Backup's advantage is rating (5.0 vs 4.2) and in-app purchases (none vs 2). On price, update cadence and device support there is nothing between them.

Both are free to download. Portable USB · Cloud Ready sells 2 one-off in-app purchases. MOMAX Backup asks for nothing beyond the download.

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.
