I was <i>really</i> impressed with the Pebble SDK on this front(aside from the one-message-at-a-time part of the comms API).<p>Solid clean C API. Phone does all the heavy web-lifting, it really is best of both worlds.<p>Also PebbleCloud is one of the slickest web IDEs I&#x27;ve seen(working emulator streaming over VPN!).
