# IDrive Online Backup vs Sync

The clearest difference is in-app purchases: Sync at none against IDrive Online Backup's 10. Sync also leads on review sentiment (50% vs 36%). IDrive Online Backup's advantage is rating (4.3 vs 4.1) and ratings volume (5K vs 805). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. IDrive Online Backup sells 10 one-off in-app purchases. Sync asks for nothing beyond the download.

IDrive Online Backup holds the better App Store score, 4.3 against 4.1. That said, the two scores are not equally well evidenced: IDrive Online Backup has 5K ratings behind it against 805, so its average is the more settled of the two. Written reviews complicate that: 36% of IDrive Online Backup's written reviews are positive against 50% of Sync's, so the app with the better star average is not the one people write more warmly about.

IDrive Online Backup ships an update every 3 weeks, Sync monthly. Both last shipped on September 22, 2026.
