Undoubtably, having the entire iPhone population at your disposal vs the limited Tile population is huge. But having bought some AirTags yesterday we discovered: you can't share an AirTag, so if my wife is out and I can't find "her" car keys then I'm stuffed. Second: we do find the facility to use the Tile button to hail your device is really useful.
Not going to lie. The Samsung's SmartTag+ us far superior. Although it doesn't have the NFC lost mode, it has a much larger range. Gets pinged more off other Galaxy phones than iPhone with their version. And has a button on it to reverse find and control any device in the Smart things ecosystem.
Released back in 2014, the once popular item tracker called Tile sat largely unrivaled until Apple debuted AirTags in 2021. Stealing much of Tile's market share among owners of Apple devices within the last year, AirTags offer a number of notable first-party features and expanded functionality compared to Tile trackers.
