# uDisk vs BackupBOT

The clearest difference is rating: BackupBOT at 5.0 against uDisk's 4.3. BackupBOT also leads on in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 2 months). uDisk's advantage is ratings volume (233 vs 7) and iOS requirement (11.0 vs 15.0). On price, ads and device support there is nothing between them.

Both are free to download. uDisk sells 1 one-off in-app purchase. BackupBOT asks for nothing beyond the download.

BackupBOT holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: uDisk has 233 ratings behind it against 7, so its average is the more settled of the two.

uDisk ships an update every 2 months, BackupBOT every 3 weeks. The most recent releases landed on September 17, 2026 and September 11, 2026 respectively.
