Pebble's big announcement: A new phone app, partnerships, developer tools and better notifications
The improved notifications are probably the biggest deal, in my eyes. If all works as advertised, you'll be able to get notifications on your wrist for any app that gives you notifications on your phone. The app partnerships sound pretty nifty, too. It's been a while since I cared much about Foursquare (although I used to play with it a lot), but if I can check in somewhere without taking out my phone, I might take another look.
The new Pebble app should be coming to Apple's App Store early next week.
