I paid for BeWeather before it was free, (which really pisses me off, btw) and I have to say that for Los Angeles, it's kind of useless. I can be standing outside, not a cloud in the sky and it will tell me that it's currently overcast. If it can't even tell me what the CURRENT temp and conditions are, how is it going to tell me the future?
I HAD WeatherBug before on my 9700, and it was amazing. Both WeatherBug and BeWeather have live radar maps. The one on WeatherBug was dead on accurate. You could zoom in right to your location and see when the rain was going to start or stop. Not only can you NOT zoom as well with BeWeather, but it's not "LIVE". I've been in my car, in the rain, and their radar had no rain anywhere near me.
Now, am I asking too much of an app on my phone? No, I'm not because WeatherBug did it right... for free.
