When buying a Bluetooth tracker, you typically need to make certain you’re getting the model tailored to either the Google Find My Device or Apple Find My network. Pebblebee recently became the first company to release models that support either, and they come in all three form factors: card, keychain, and ultra-compact tag.
I like the no vendor lock in approach as I moved back to Android a year ago but am still stuck with my AirTags, and get daily warnings from my Android phone that an unknown tracker is following me.
These tags are probably ideal for those who are not 100% locked into one phone ecosystem. Hopefully it encourages other manufacturers to also provide this functionality.
