I think you should update your mobile application. You should make it so that there is easier access to the buy and learn section as well the forum also if you could update it more frequently as far as I can tell its never been updated before. There should be a way you can access the yoyoexpert web site without going to safari kind of like the blog tab but with out the upper tab.saying"Blog"
It also should be able to help you upload your photo (profile pics,etc.) easier, I really want a mobile shop section with fast checkout , push notifications would rock! And a mobile learn section (nice one I didn’t think that one up ) if this app is successful I think Andre could charge for it $0.99 think of the profits!
