AccuWeather.com is probably one of the most known weather websites in the world (together with weather.com), and it has, of course, a dedicated app in the Android Market. It has been recently updated (I don't know exactly when because I just came from Greece and I couldn't see there any updates because of the weak connection I had), so I updated it today.
It has a much cooler interface than before, but, unfortunately, it crashes every time I try to open it. It can be used for about one second, then, it stops working and has to be force closed. I'm running Android 2.2 on a Nexus One, but it seems that this doesn't matter, as everybody reports the same problem after update. I've already reported the problem, and the guys from AccuWeather have to move fast, because even if the app currently has 3 stars and a half, I'm sure that its rating is going to fall soon.
