I contracted out my mobile app design and I would a developer to implement it for me. These are the files that the designer gave me:
A zip file containing all the fonts
512x512 icon (PSD)
1024x1024 icon (PSD)
640x1136 (PSD) for the main screen
640x960 (PSD) for the main screen
640x960 (PSD) for the 'add new item' screen
640x1136 (PSD) splash screen
From these files, it should be enough to update my ios app for both iphone 4 and iphone 5 retina. You will have to extract the PSD and embed it into the current app. My project source is hosted on a private repo on github so having a github account is a plus. I'm mostly interested in applying the design from the 'main screen' and 'add new item' screen as I can do the icon and splash myself. I use xib's for my views as much as possible.
VERY IMPORTANT: To separate you from the spammers, please write 'IOU APP' as the first line of your bid. We will delete all bids that do not start with this phrase, since most bidders never read the requirements. Thank you for being one who does.
