Pebble is part of the Made For iPhone program, a requirement that hardware accessories must meet to interact with iOS apps. If an iOS app uses PebbleKit iOS, it must be whitelisted before it can be submitted to the Apple App Store for approval.
The iOS companion app must only start communication with a Pebble watch on an explicit action in the UI. It cannot autostart upon connection and it must stop whenever the user stops using it. Refer to the PebbleKit iOS guide for details.
com.getpebble.public is the only external accessory protocol that can be
used by 3rd party apps. Make sure this is listed in the Info.plist in the
UISupportedExternalAccessoryProtocols array.
Pebble may request a build of the iOS application. If this happens, the developer will be supplied with UDIDs to add to the provisioning profile. TestFlight/HockeyApp is the recommended way to share builds with Pebble.
After whitelisting of the new app has been confirmed, add the following information to the "Review Notes" section of the app's Apple app submission:
Note: An iOS app does not need to be re-whitelisted every time a new update is released. However, Pebble reserves the right to remove an application from the whitelist if it appears that the app no longer meets these requirements.
