Exactly what I want in a weather app

I work with folks world wide. The vast majority of them are international and hence don’t depend on “freedom units” for things like temperature or distance. This gives me both F and C temps in one well designed view. Will be donating money via Venmo because this app will help me as a typical uneducated American learn a little bit more about this tiny rock near the sun we call Earth before I expire all too soon. Thanks so much =)

Simple and exactly what I was looking for!

Wow, great app! I found this from a Quora thread while looking for recommendations for a side-by-side F/C app (thanks, Bjorn, for the link!). Works smoothly, very easy to use, and it’s simple without all the ads and graphics other weather apps have. This means a quick load time, which gives me the information I need almost instantly, getting me on my way quickly. Definitely will be recommending this!

Thank you!

By using your application, I learned to think in both measures. After two weeks of using it, I asked my husband to challenge me if I could translate from one to another by heart. I was mostly accurate despite the 1-2 degree differences! Thank you! It replaced my built-in weather app!
