Excellent weather app

A well designed weather app - doesnt have the flashiness of some weather apps but it doesnt need it as that it provides a lot of information in little space.
Would like to see an update for the retina display and if possible USA locations.

UPDATE:
Version 1.5 updates when you shake it - I initially thought it wasnt updating - ingenious way to save hits to environment Canada. 

Great app, and great update!

Edit: the shake is a bit of a pain - you have to shake it hard. Please change the update method.
Still a 5 app!

Update: v1.5.1
The shake to update is not sensitive enough - I have to shake my phone quite hard to get an update. In communication with the authors, the are some alternative methods that they are looking at to evoke an update.

4 program due to the update mechanism (it feels like I really have to whip the phone to update and it can be unnerving for me and distracting for others).

Not Number 6 about Atmosphérique
