One big breakthrough was discovering that Pebble had an internal feature for its iOS and Android apps that would let them swap out the app store for a different one. Fitbit found out about this, and actually opened it up for Rebble to use. "In one of the [software] versions Fitbit actually exposed this thing we've been exploiting, which allows us to use their apps with our app store, which is pretty cool." Fitbit has continued to update the Pebble software with minor bug fixes, to the surprise of some in the Pebble community.
