This is in no way a correct implementation of the Tile protocol, rather a simple app, aimed at making the trackers ring without the official app. Use at your own risks.

Retrieve your devices Mac addresses and auth keys. This can be done with

https://github.com/bachya/pytile

import asyncio

from aiohttp import ClientSession

from pytile import async_login


async def main() -> None:
    async with ClientSession() as session:
        api = await async_login("<email>", "<password>", session)
        tiles = await api.async_get_tiles()
        for tile in tiles.values():
            print(tile._tile_data["result"]["auth_key"])


asyncio.run(main())

Then, you can fill example.env with your values. The name field is used for display, pick whatever works for you.

Finally, you can run this app on your phone:

flutter run --dart-define-from-file example.env

And you can install the release version if you are satisfied:

flutter build apk --dart-define-from-file example.env
flutter install --release

This has only be tested on Android, it may or may not work on iOS. It will not work on other platforms.

This app requires bluetooth and location permissions.
