This is not so much a mobile app, it is more a mobile website.
NouveauRiche.mobi will be a mobile magazine about saving money, and making money.
On the site will be links to free samples and coupons, there will be material on how to make money from home online, and material on how to save money.
The primary content of the homepage will be articles/blog posts.
For colors I would mainly like warm colors like orange, green, red, brown. I didnt want to say too much because I don't want to limit the designers.
As for the logo. I started another contest for the logo here https://99designs.com/logo-design/contests/create-next-logo-nouveau-riche-188622
The target audience are people from all walks of life, who are interested in getting more out of life. This could be the stay at home mom trying to save money at home with clever tricks, but also the desk job computer programmer starting his online business and making it big. We really see al kinds of stories, it's mainly people that have a positive attitude towards growth and self improvement.
Most of our customers use Iphone, and Samsung GT-i1900 or Samsung GT-i1901
