Unreadable widgets

[Franckielestore]

In your opinion which of these three following widgets showing daily forecasts is the most readable? And the less?

You have to figure out that in this post, this is way bigger than on an iphone screen

The less readable one is the one of Windy Premium.
Very small symbols (should be 3 times the size), bad choice of colours and background.

Why is it so difficult to design a widget that users can read easily?
