Sorry I know this is $18 but I can tell you this is not an ad and I have saved way too many hours using this as a starting point. It is the one app that demoed Ionic/Cordova power to its fullest. You can not find this level of features, details and documentation on Github or Codepen folks!

The author is very supportive and answered all of my questions. I know this may look like an ad but I really hope the admins allow me to post this here, you can not find anything anywhere near this level of out-of-box functionality as a starting point!
If you are on Android you can download the demo APK and try it out!
