S4BB Limited is a well-known BlackBerry app developer. As they’re branching out to Android & iOS, Emkore Limited was commissioned to rebuild one of their most popular apps, “Petrol Usage Tracker” for Android & iOS.

Using Google’s Flutter framework and Material Design, Emkore set to work to build Fuel Usage Tracker. S4BB Limited was keen on maintaining continuity between the old BlackBerry 10 app and the new Android and iOS apps, while still improving the new Fuel Usage Tracker app. Emkore succeeded in doing so by reusing the same color scheme, and applying it to a fresh user interface. Internally, Emkore improved vehicle profile management, and made location based settings such as currency and measurement units a lot simpler.
