Apple's network has the majority of iOS and iPadOS devices on the planet tracking for it.

Google's network has whatever subset of Android devices are running a new enough version of the OS and have opted in tracking for it.

Tile's network has whatever subset of both iOS and Android devices where the device owner either has/had or is close with someone who has/had a Tile device, installed the app, hasn't uninstalled it, and the app hasn't had its permissions revoked automatically due to lack of use.

It's just not comparable. Tiles are fine around the house or in densely populated areas where you can generally assume someone with the app is going to be nearby pretty regularly, but if you lose your keys on a hiking trail and someone else picks them up so they're not wherever your phone last saw them you're probably not getting any updated info any time soon.
