Xiaomi MiBands are surprisingly good at what they do, especially for the money. Not a premium product by any stretch but still nice. I like it especially because it looks more and more like a simple bracelet with each iteration, instead of trying to be watch, huge watch or mini-ipad like the others.

The bands also last way longer than any fitbit I had.

Of course, you health data is probably going straight to CCP but then you already have Android.
