Looks interesting and it's a nice feature. Not sure if it is a standalone app though - I have the default weather app that works just fine.

However, you have something that would be valuable to other Apps such as Next, New Look or similar (I'm in the UK, so these shops may not be relevant to you.). I would suggest approaching them and offering to license your software so every morning a push alert is sent to their users with the weather for that day and a suggested outfit from their shop. That is the only route to real monetisation that I can see.
