Hehe i never noticed. Just tried on my poor ipad and I end up with same. I owned this app (it's running in the background with stupidest os ios 7 ). It's not wpcentral developers fault it's App Store issues. You know I am facing a weired problem with my itunes on my pc. I have purchased some app from different country (temple run oz was free on United Kingdom AppStore in November. Now when I go to my pc and open itunes, check app for updates (500+ apps hehe I am crazy ) it says all apps are upto date from past 7 days but it's not true. I saw facebook messanger got a update recently and it's not showing up. I binged this issue (no google hehe ) and ended up in apple discusions and I found that many other folks are phasing this weired problem. The solution is to delete all the apps you have downloaded from differmt country AppStore. I deleted 4 apps I downloaded which were not avaliable in my country (India) amd then check for updates. I got 43 app updates(dead trigger,twitter etc etc ). And yes don't forget how ios 7 screwed my device.
Moral :- I wish never invested in apple ecosystem. I made a wise choice to buy windows phone. Now looking for a good windows 8 tablet.
