I found an AirTag alternative with more useful features and works with Android phones, too
Briefly

Chipolo's new finder tags for Android users are making strides to close the gap with Apple's AirTags, offering a robust integration with the Google ecosystem.
The One Point fob is user-replaceable and splashproof, offering a range of 200ft, making it a versatile option for tracking a variety of items.
In contrast, the Card Point maximizes thinness at the cost of a non-user-replaceable battery, a compromise that may not suit all users.
Chipolo enhances the user experience by offering a 50% discount for future purchases upon registration, showcasing their commitment to customer retention.
