UUID holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: My Device ID by AppsFlyer has 41 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 63% of My Device ID by AppsFlyer's written reviews are positive against 50% of UUID's, so the app with the better star average is not the one people write more warmly about.
My Device ID by AppsFlyer ships an update every 10 days, UUID every 2 months. The most recent releases landed on November 11, 2026 and November 3, 2026 respectively.
