To expand on this:

Carrot weather is a somewhat silly weather app. It is serious in that it aims to provide a very solid outlook on the weather with a highly customizable UI -- in fact you can even recreate the dark sky app’s UI if you'd like. However it is silly in that it comes with an “AI” “assistant” who spawns challenges and achievements.

I don't mind much but it can be a bit distracting in a weather app for the assistant to talk about our relationship.
