Verdict
The clearest difference is review sentiment: U8 at 64% against MOMAX Backup's 18%. U8 also leads on ratings volume (10 vs 2). MOMAX Backup's advantage is rating (5.0 vs 4.1) and in-app purchases (none vs 1). On price, update cadence and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. U8 sells 1 one-off in-app purchase. MOMAX Backup asks for nothing beyond the download.
MOMAX Backup holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: U8 has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 18% of MOMAX Backup's written reviews are positive against 64% of U8's, so the app with the better star average is not the one people write more warmly about.
MOMAX Backup ships an update every 3 months, U8 every 6 weeks. The most recent releases landed on October 7, 2026 and October 24, 2026 respectively.
