I am making an iPhone app for GW2. It will be going live in a few weeks and I would love some feedback. The main purpose of the app is to send you push notifications for a state change for any dynamic event in the game (Like when the shatterer has landed). If you are interested I am using TestFlight for sending out builds. Please use the link http://tflig.ht/1d1a2JB to register if you are interested.
