The best key finders are great tools for hunting down lost stuff, but they've only ever been as effective as the network behind them. If they're not within the proximity of someone with a specific app, they're not getting found. Apple's AirTag changed that situation, since the company's established Find My Device network was installed and active on a huge number of Apple devices worldwide.
With the sheer number of iPhones out there, the odds of finding your lost keys or bag became a lot higher. We've since seen Google start offering compatibility with third party trackers, offering a similar deal — using nearby Android phones to track stray items and offering a better AirTag alternative.
