It's never ok to pay ten bucks for weather, sorry.
its not the app that alot of people pay the 10 dollars for. its the developer, there's a free version just like ubertwitter but to show your appreciation to the developer you buy the app for all the hard work that has gone into it.
Best paid in my opinion is My Cast but it is a bit pricey. Great radars that let you move around the country and nice looking too. However the home screen icon isn't made to show current conditions and there are no weather alerts that show on the homescreen. I use My Cast email alerts for weather alerts and the free berry weather for the home screen icon.
BUT BERRYWEATHER HAS NO COMPARISONS ... IT'S SIMPLY THE BEST, IN MY OPINION. VERY MUCH WORTH THE $9.99, CONSIDERING I AM USING IT THROUGHOUT EACH DAY, AND WILL CONTINUE TO DO SO FOR THE DURATION OF MY 2-YEAR CONTRACT ON MY BB TOUR 9630. I could list a dozen reasons why I like it the best, but I won't bore you with all the details.
Honorable Mention: The weather function ("channel") on Viigo is surprisingly well-presented, visually pleasing, & easy to use. If there were no BerryWeather available, I'd just use Viigo over the weather-specific apps.
Note:
BerryWeather goes by the name "BeWeather" on BlackBerry App World. I read somewhere that the reason is due to naming restrictions set by BlackBerry. But it's the exact same, high-quality app.
You can put BerryWeather on your home screen (if you want too) and it will update automatically to current conditions. Below are a few examples, but there are almost unlimited ways you can use this app on your home screen. Or just open the app to view all the items you wish, in the font size and icon size of your choice, and use your home screen as you normally would. It's up to the user, and none of the other apps have this much versatility.
