Very helpful

Didn’t think I’d need it, but traversing the solar system is a lot less perilous when I know what the weather on Mars is gonna be like :) 10/10, haven’t been caught out in a solar storm yet

Simple, not annoying

I love this app. It looks a space enthusiast said to himself one day, "Self, I wonder what the weather is like on Mars right now.... I know! I'll write an app for that!"

So he did. It does what it says it would do, and it's not annoying. Thank you, space enthusiast!

I like this, but have one suggestion.

While the app is great, and it looks great, is it possible to have an action for twelve hour time instead of twenty four hour time? I know Mars time is a little different, so if not it’s OK.
