What is Gadgetbridge?
Gadgetbridge is an Android (4.4+) application which will allow you to use your Pebble, Mi Band, Amazfit Bit and HPlus device (and more) without the vendor's closed source application and without the need to create an account and transmit any of your data to the vendor's servers.
The graphs could indeed use some work, but it pairs just fine with the Mi Band 3 & is available on F-Droid. Also successfully updated my Mi Band 3's firmware with Gadgetbridge, but your mileage may vary.
