I recently opted for AGL..First of all Great App. There are many functions which great to have.. especially like connect with Google Home.
There are few things which I thought could improve user experience (although I am a UX/Journey Expert), here’s one of those:-
App Screen 2 - Usage Screen. In the usage screen where you Past Usage are getting displayed. The current chart dialysed is Horizontal Bar chart. Ideally nothing is visible in this chart (I know user can click on this chart and see the details.) I would suggest try changing the Horizontal Bar chart to Donut (showcasing based on Month or Devices would Users to understand the Usage).
