The app has to have the same (native) functionality as our online web-platform provides. Our system already has JSON API and we can extend it there where functionality is missing. Our website [login to view URL] shows a guest login which you can use to get an idea of the things to implement. Most important aspect is measuring point creation screen, project management, notifications and the graphs. I don't to simply have the web pages managed by the app, it has to be an app that works very smoothly and only collects data through our JSON API. We need all source code uploaded to our private github repo and we will own the IP. You will need to help us get the app signed for Play/App stores.
