Need someone to develop an iPhone app for my LED lighting business to show the savings for going to LED lighting from halogen/incandescent lighting. We would provide the details for how much power each uses and then the app would need to work out the savings per year from the amounts the user puts in. We will provide the information of what exactly we are wanting in the calculator eg power savings, energy savings etc. we will provide images of our products and our logo, we will create a rough design of how we would like the app to look but the design can also be your own creation.
