I like dark sky.

They have an app also but I just use the website.

Not as good as a layout as WU was, but I'll take it :)

It can’t be downloaded on iOS in Germany it seems.

You get all the features on their website too. I found a simple homescreen-link perfectly enough for my weather needs.

Presumably it has the same policy because it's also owned by IBM.

I wondered why they wanted it...

I used to think it was all the weather station data points but that became clear it wasn’t a priority considering how much their apis error out and how slow they are to fix. I think we just got our answer though.

They also took down a great little website they bought called Weatherbonk and never ended up using the site’s best features. I wonder if they were just buying up competition.
