I architected the iOS app in Swift which is used by drivers, hauling water or waste products, for data collection (route waypoints, shifts, field tickets, etc.). The app collects location data in a manner similar to how Uber works (the data can be replayed later to view the route taken by the driver). Realm was used for local storage of data. AlamoFire was used for network communication. - iOS App: Movemedicalhttps://www.movemedical.com/product/
