Eric Migicovsky, leader of the revived Pebble, is making smartwatches for himself. You’re just along for the ride.
“Apple makes it incredibly difficult for third-party devices to interact with things like iMessage or Siri or any of the built-in features on iOS,” Migicovsky told Gizmodo in a freewheeling video interview. “And that sucks. That sucks for competition. That sucks for innovation. That sucks for price.”
I never used the bangle.js but I was tempted to get it a few times.
But IMO, Pebble OS feels quite well developed. The main parts of the interface are basically unchanged from the original Pebble Time if you’re familiar with it or have seen it before. I think the community around it is also bigger, so a lot more community development, apps, watch faces, etc.
