Both are free to download. IDrive Online Backup sells 10 one-off in-app purchases. Koofr asks for nothing beyond the download.
IDrive Online Backup holds the better App Store score, 4.3 against 3.8. That said, the two scores are not equally well evidenced: IDrive Online Backup has 5K ratings behind it against 29, 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 54% of Koofr'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, Koofr every 5 days. The most recent releases landed on October 14, 2026 and October 6, 2026 respectively.
