Like the clean and simple layout, as well as the use of font choice for this app.But! You need to consider an ad free option and a potential future subscription service. The ad in the middle of the screen of the app layout takes away from the test of the design. I would be willing to pay three or four dollars to get a pro version upgrade.I like how you have added the air quality index into the app. Maybe one day, you can add in weather alerts that are fed by the National Weather Service offices for the areas they are responsible for.Add some other settings options like a dark background with some font color choices.May I suggest you look at other more established weather apps and gain some ideas as to what would work in improving this app. It really shows promise!
