One of my favorite cheap tech finds is a no-name, small OLED smartwatch that cost under $20. It has all the basic fitness features, an app that is surprisingly nicely done, and it exposes all its data to Apple Health.

It supports the limited notifications API that Apple exposes, so it buzzes for calls and can show you text messages you got. Does music control, raise to wake. And somehow with all of this, it has a battery life of about 10-15 days on a charge. Unbelievable that the Apple Watch adds really only two important features I care about (making your iPhone beep, and Apple Pay) but only lasts a single day on a charge, and costs nearly 10x what this one does.

Anyway, it also comes with about 100 choices of faces. I only wish it was open source or at least an "open" platform so that I could make my own.
