Thanks for the input, Corion.

As an Android user, who's a seasoned web systems developer, I'm sick and tired of being asked to download apps from whatever app store, to do things that are easily done by visiting a responsive web site.
There are times that an app is needed, as I have recently found out with a mini web app I wrote for tracking a mobile device using the browsers' geolocation api and feeding the positions to our server via AJAX and JSON.
Despite my attempts for power management and permissions to the mobiles' Firefox, my "tracker" web app kept going to sleep when the screen of the phone went off, or the browser went to running as a background app.
Apps seem to make better use of the device than a browser app does.
I am actually all for abolishing app stores and pushing users to apps developed in the browser, either with frameworks like React and AngularJS or by ensuring that web sites cater for every client, using well defined and corporation neutral technologies.
