Remember, this isn’t an app, but a widget: you can only access it by placing a widget on your homescreen. You’ll notice that there’s only one widget (we’re missing different size widgets, only available in the full version) which is a battery level indicator. However, the widget isn’t the most important point of this app, but its battery tracker.
