backgroundTracker4WebApps (BT4WA) (Android app)

Background location is allowed on native apps but not on web apps

What does the app do?

The app is a tool that allows the user to enter a list of URIs (sites), to which the location is sent in the background.

How is the app meant to be used?

A web app developer (and corresponding web app) can support BT4WA and thereby allowing the end user to share his/her location in the background.

Example: A taxi-web-app can allow taxi-drivers to track themselves to potential customers.
