Very good app. I like the visualizations, and the widgets are useful. It would be great if the app had a way to exclude zero-rated data usage from monthly limits. Unfortunately I need to take a star off as recent versions have started demanding location permission on every launch with no way to dismiss permanently (the app still works fine without it though).

I'm using this app from Bangladesh. After the update, I noticed that the reload option is missing. Is it a change or the option is missing accidentally?
