It turned out the only functionality a significantly larger userbase than Pebble's early adopters found interesting in a wearable device was fitness tracking related. They pivoted too late to accommodate that.
The timeline concept on the Pebble was great, and no one currently come close to it.
If I'm going to wear a watch, it better excel at telling time and show me time-related events in a clean way.
I love the timeline, showing my calendar appointments, seeing notifications(and being able to use some of the Android notification commands on them), fitness tracking, but most important of all, battery life, I love not having to recharge my Pebble every day.
I liked the idea of Nokia Steel HR for instance, but there's little screen real estate for a smartwatch to show me notifications and appointments in a proper way.
