I had a look at the Zalando app on Android and I though about a redesign of it. I applied the Material Design concept and come up with this design.
I also spent some times in building a prototype in Pixate. The prototype is optimised for the Nexus 5. It work also on the iPhone (I tried on an iPhone 5) but it looks a bit different, and also behave different. Anyway, If you wanna try the prototype be sure to have the Pixate app installed on your device. Then open this link from your device and you will be redirect to the Pixate app and...here we go! :-) No need to login or create an account! :-) Here the link: http://pixt.io/p8d28bbb49be6
On the prototype you can scroll the home page, tap on the first item on the list (this brings you to the shop page – also scrollable) and open both side menus.
