Launched last week as one of the great attractions of the first event of Apple in 2021, AirTags are a revolutionary tracking system that promises to make it so you'll never lose your keys, glasses, or wallet again. Apparently, with one limitation: as long as they're not in tall buildings on different floors.

The issue was cited by XDA-Developers editor Ben Sin when he posted a AirTags review this week. Ben said he had good impressions of the devices, although they do not offer much use to the editor at the moment. Positive points were described, such as the simplicity of configuration, good functioning and ingenuity of the technology.

However, part of Ben's experience was not positive, as he lives in a building with access to different floors, such as a common area, terrace, gym area and reading room. If Ben loses something on the terrace, for example, and goes to the reading room, the AirTag will not send an accurate location, which is likely to happen in other buildings like his.

It didn't work for either general tracking or Precision Finding (a precision finding feature supported by the iPhone 12 and iPhone 11). In the first case, the map will indicate that the lost item is in the same area where Ben is, just on the wrong floor. Precision Finding, on the other hand, works, according to the editor, for distances of up to 9 feet, and even then, only for horizontal use situations. It would be useless if the lost item is in the same vertical position as Ben on a different floor.

On the same floor, it's like a house. But AirTags, for those who live or work in tall buildings and run the risk of losing their things on another floor, may end up not being very useful.
