ABB is the leading company in industrial digitalization. One of theis companies is Niessen, that produces swiches and domotic controls for the home. 

Their app catalogue was the first app i designed, back in 2012.

It was designed only for iOS, both for iPhone and iPad, but there was also a webapp for desktop. Based on iOS5 UI, it was not just a still catalogue. The switches can be customized (frame and button), there is a background gallery or the user can take a photo for its own background. 

After researching through similar apps i had a clear idea of how the selector could work: swipe for navigating models and tap for customization. It was the early age of apps, at least for me, so these were my baby steps in app design, studying deeply the interaction and gestures. 

Ease of use was a must for me, so i designed the navigation with the two simplest gestures on smart devices, swipe and tap. There were also little surprises in hidden features, as the switches' lights in some models, that can be light on or out. 

As ABB is a worldwide company with a very defined brand style, there were styleguides to be applied. Splash screens, home and info screens had to stick to brandguides, as well as the app icons. 

Delivering assets to developers was also a tuff task. First, all the crop and retouching work (more than 200 images), but specially, organize them separetly on collections, models, colours and parts of the switches, and resolutions, so there were no confusion possible when developing the app. 

Though this is an old project, i'm still fond of it, even if it looks a bit outdated visually nowdays. :)

It is still available on the AppStore.
