Just downloaded the update. It managed to crash the first time round (also really first time Pebble watch crashing on me). I'm guessing the watchface wasn't updated to work properly with the new timeline preview ("Glances") - I'll debug it if it crashes again.

So far I'm very happy they've updated the Pebble Health watchapp - it's finally usable now (and quite nice), as it display daily stats for last week in nice bar graphs. Also I have an impression that Timeline is a bit more responsive/faster now.

I'm pretty happy with what Pebble is doing (though Health interface on the mobile app could use some further rework to provide more/better information). Can't wait for the Time 2 watches to start shipping!
