This design contest is for redesigning the UI only (how it looks- icons, button, colors, etc.) of an existing app. I'm still happy with the UX (how it functions- layout, ordering, etc.), but the UI is circa iOS 5 so it looks dated. I'm looking to update the UI to reflect the design changes that came with iOS 7/8. More info on that is available in Apple's human interface guidelines:
Again, do not change the layout of the provided comps. I'm just looking to update the aesthetics, and would like a total update to all icons, colors, fonts, etc.
For the App Icon you can make changes beyond just the color, but I want it to look like a natural evolution of the same logo. The updated icon should contain similar elements to the original.
The app relies heavily on text so it should very readable. My customers have complained that the current color scheme makes some text hard to read.
Most of my customers are middle and high school teachers (and their students), but the app has users in other industries as well. I want the new look to be a little less influenced by the "grade school look". Something a bit more modern, sleek, and universal would be nice.
