This looks real similar (in the idea) to an app I developed for the client of an old employer I worked for. Unfortunately, my employer went belly-up before it was completed. We were in the early testing stages, trying to work out a few bugs. The back end was based on PHP and something called "Whitebox CSS Admin" template, and the app was developed using PhoneGap and JQuery Mobile (this was sometime around 2012). It was very interesting to develop, and the first JS SPA I ever did (before I knew the term). I'm glad to see that someone has done something similar. Good luck with it!
