Just an FYI - there was a Pebble watch update last night (OS 2.9.1) so this could potentially fix some of the disconnection issues written about in this thread.
Every update they release says something about connectivity issues....going on a year with my Pebble and have always had connectivity issues since day one.
In fact, I jailbroke my phone at one point, downloaded background manager and forced any pebble related apps to always run. Still had connectivity issues, despite the global override to allow apps to run continually. Also downloaded Smartwatch+ off of Cydia to grant my watch additional features not normally available through iOS.
That being said, the pebble is a nice watch and I have enjoyed having it overall, however, functionality cannot be compared to the Apple Watch.
Different strokes, for different folks, I am willing to give up sleeping with my watch to have functionality. As of right now, my fav thing about the pebble is the alarm in the morning, allows me to have an alarm and not wake up my 4 month old...but having a watch that works best while I sleep vs one that works best all day????.....hmmmm, but hey that is just me.
And I'll take my chances with my daughter waking up to have an apple watch lol
