I was the lead UI designer, tasked with creating visual systems for the app. Color usage guidelines were made to hand off to other designers. I provided the initial UI styles for iOS and then worked with a team of two other designers to complete both iOS and Android. We delivered 2 style guides, one for iOS and one for Android.
*Typically we wouldn’t use Roboto for an iOS app, but parts of the app were WebView and the client had requested that the fonts in the app match their site which was Roboto.
