At the risk of reviving a dead thread, I just wanted to throw my 2c in.
I'd rather see an in-game addon rather than an app for any mobile phone. Some people have iPhones, others have Android platforms, others have 'Others'. But everyone seemingly uses GearScore these days.
GearScore won't go away, even though everyone hates it.
Please release an addon. It's long past time for Wow-Heroes to stand up and take its rightful position at the head of gear optimization.
It should be sufficient to keep the site mobile-friendly. One way I've seen other sites do that is through the addition of a separate site (ie. parallel pages) that presents the data in a mobile-friendly way. http://mobile.wow-heroes.com/ exists, although it looks the same as www to me.
Yeah like that chick said ^^^ we don't need an app for a specific phone, but it would be really nice to have a mobile version of the website that automatically detects if you're using a mobile browser (with an option to view the normal website)
