Update existing android app to Material design

Current app works and function well, however certain aspect of the UI / UX needs updating to fit the current Material Design guideline that is set by Google. We need a designer / developer that can implement the changes. Also, designing and implementing additional layouts(custom) for devices with different size and density ([login to view URL]) including horizontal layout. Some addtiional function and options that works with the existing back-end will also need to be added. We have at least another Android app and iOS app that require updating as well, so if the current project is completed as promised, we will be more than happy to offer more projects.
