If you discover a fault in this plugin, please let me know.

Does the Watcher gets removed when closing the app? Or is there any option to do so?

[diachedelic]

If by "closing" you mean "killing", then yes. If by "closing" you mean "backgrounding", then no. If you only require updates in the foreground, simply omit the backgroundMessage option.
