visually i really appreciate this app. it is minimalistic and lovely.
interaction wise it could use a little more finessing. the vertical navigation is tap based and the horizontal is swipe. it doesnt differentiate between up and down swipes and taps, which is a little confusing.
the real trouble with this app is the load times. i am in north america, so this could be a locality issue, but i generally have to wait about 5 seconds staring at a blank screen with a loader bar on it before i get the data. sometimes it gets my location, other time not. performance wise i have no other weather app that behaves this poorly. and weather is one of those things you really want instantaneously.
all in all it is attractive but the performance makes it unusable. truthfully, with some development tweaking this could be a five star app.
