Conference Social Network Mobile App

APPEK was great to work with. I was really spread out, so I had three mobile teams and the Web team that I was handling. We were working with an agency that also had to do the design specifically for mobile, and they had really focused on iPhone. They had only secondarily done the Android design, and they were not nearly as familiar with Android. Not that it’s that much different at this point, but APPEK was really great because they were able to take a lot of the iPhone assets, or assets that were closed, and either guide the designer or take the assets and rework them. They also came up with some really good ideas about how to do certain things that weren’t really well defined. They contributed some good ideas in terms of the interface and functionality. They really worked without a lot of guidance. I was able to say, go ahead, go for it and let’s talk in a few days and see how it comes out, and they were always just right.
