ive had this app for a bit now. it looks great, op did a good job with its design. its handy for checking the daily zaishen quests and for any news from anet. i dont check anything online for anet blogs and stuff, so i always pull this out when im bored and see the news. It also has a HoM reward tracker that is set up like the one online, but you gotta individually check your achievements. the only problem ive had is that it seems to take a while to load the news feed and sometimes it doesnt load the news at all. i probably use this a few times a week. its great and its free! i recommend this if you got a windows phone.
edit: i also agree with the above post about a game update feed.
