I check them all and choose the nicest forecast

Nothing really compares to what Dark Sky was, but MyRadar is as close as I could find and I've tried all the major and some not so major apps on the Google Play store.

I use the one in the pic, and I have to say it is pretty damn good at predicting rain.

The weather channel app has some pretty good widgets. No adds on the widgets either

Any app that works with the Spanish weather provider will have the best predictions possible for me, it's sad that most don't let you swap providers.
