ZSWatch – Open-source Zephyr-based smartwatch
It's looks so interesting, but:<p>No GPS.<p>My BangleJS has GPS but it is really tricky to get it synchronized with the satellites. I go for a run and then check the data and it's missing half of it because it couldn't pull the updates.<p>AsteroidOS is cool but none of the watches really work well.<p>I have a recent Samsung watch and the battery life is poor enough that I'm always forgetting to charge it.<p>Sorry for the buts. This is a really cool project, I just am surprised there isn't a perfect smart watch that's open source. Or even a closed source watch that is hackable.
