I looked into Amazfits, and the UI is not great in English. It was clearly designed for the Chinese market, and the international edition was an afterthought.

I looked into Amazfits, and the UI is not great in English. It was clearly designed for the Chinese market, and the international edition was an afterthought. The screen is also totally different from the Pebble. If you put an Amazfit in always-on mode, the battery won't last nearly as long as the Pebble. Also, the Amazfit not as readable when outside. More importantly, any device that is going to have access to my real-time GPS location needs to be as trustworthy as possible. Most apps can be prevented from getting your location because your smartphone will only give it to apps when you grant permission. But an app that syncs with your GPS-enabled watch doesn't need permission to get your location because it already has it. I don't fool myself into thinking that anyone is especially interested in tracking me. But given the choice between Eric and a Chinese company I don't know anything about, I choose Eric.
