This was definitely the most involved app design I've taken on. Telus has always had an account management app, but it never lived up to their motto of Future Friendly. The app was redesigned in parallel with all of Telus' online properties giving me a new colour pallet to work with. Customers are greeted with the recognizable "white world" of Telus, but once they dive into the experience the app takes on a new look using dark grey to represent their personal information.
The client was ecstatic, and the app is currently rated 4+ on the iTunes App Store. (Out sourcing the development cost us the full 5 stars)
