I'd like to start off by saying I LOVE your app. In any business, it's hard to find people who are absolute fans of yours, and I'm one of them. Your design, usefulness, ease of user experience should be more known.
But there has been one thing lacking. Something, not making the experience whole.
I just wish it had just one thing...
Support for iOS (and Android?) widget.
I may be over stretching it, but if it had this, I believe you'd be a dominant force in the mobile app weather category.
Currently I use WeatherBug and think they do a good job at displaying useful weather/forecast info, but feel your app/service can deliver so much more.
Unfortunately, in my daily routine of using apps i follow the 80/20 rule, and don't get to enjoy your app often but think about how great it was to use your app from time to time. So, I figure I'd reach out to let you know, so I may use it everyday.
I hope you consider this, and thank you for your wonderful services.
