AppAdvice has once again teamed up with Byss Mobile in order to offer you a chance to win one of nine promo codes for InstaWeather Pro ($0.99) for iPhone and iPod touch.

At first glance, you may think InstaWeather is another weather app. However, it’s not meant to inform you of the weather. Instead, it provides the opportunity to flaunt the currently perfect weather conditions around you.

Just take a photo of that hot and sunny day at the beach or the walk through the park during a calm and clear evening, select one of the nine weather report skins, and share. Each skin has a different focus, such as temp or location, with its own set of weather data. In addition, skins can be moved to the top or bottom and be displayed in your preferred measurement units.

In regard to sharing, as the name would obviously imply, InstaWeather is primarily designed for Instagram users. Nevertheless, it’s also possible to tweet, post to Facebook, and save the final image to the iOS camera roll.

To have a chance at winning one of three InstaWeather Pro promo codes, just hit that tweet button near the bottom of this page or retweet this post from your favorite Twitter app before Sep. 28 at 11:59 p.m. PDT. We will then search the Twitterverse for all of the retweets and randomly choose our lucky winners. The winners will be notified via Twitter, so please be sure to follow us so we can send you your promo code via a direct message.

Non-Twitter users and those of you who want to increase your odds of winning can leave a relevant comment below before 11:59 p.m. PDT tonight to have a chance at winning one of the other six InstaWeather Pro promo codes. If you do make an entry via the comments area, please be sure to also check your junk email boxes so that you won’t miss out if you win.

Feel free to participate in the giveaway via either or both methods. Only one entry per person per method is allowed, totaling up to two entries per person if using both.
