Need fixes to my coupon based app for Apple's IOS -- 2

Hello. I have an app made on iOS that basically allows me to login to Facebook, track nearby deals by taking a picture and sharing it on Facebook. It's already 70% made. It's already mostly finished so this shouldn't take longer than 3-4 days to complete. 1. UI - modify some text changes and merge the about us/contact sections 2. Add a reward system, basically the more locations the user visits little by little they add points until they get a reward when they complete the points - the reward will be a simple image (not on the existing code something similar already exists) I already have the code, which will be sent for you to modify. Note, you will be working with a Cpanel and mostly the backend, although you will be making a mockup UI for the frontend. API knowledge is needed to complete project.
