Recently I have made this app commissioned by my college to make an app where you can trade and share information. I chose for an application where you can up and download photos and photoalbums, and you can share them with your friends. You can link each album to the relevant 'friend' you want to share it with. 

There are two mockups here under, who show the -sign in- and the -profile with friends list-.

After sketching the app I made these wireframes before I started with the prototype. The green areas show how you can navigate trough part of the app.
