Develop OS & Andriod app

Need an Mobile app developed on discount coupons but there is small difference , the app is suppose to give code on which people can avail discounts ... So the working will be say a user finds Nike Tshirts on flipkart when he goes to apply discount code, the app shows multiple discount codes with little description of say 1 sentence for each code and the person when chooses the same the code is applied !! This will save people from tedious job for looking for an discount deals on Google instead it's there on the app !
