Modify an existing iPhone app and an existing iPad app to add (1) Supervisor Approval, (2) Team Punch features. Both iPhone and iPad apps have different interfaces (one was built specifically for iPhone's UI, and one was built for iPad's UI). We recently modified both apps to work with iOS7; both are in the App Store. The backend for the iPhone and iPad apps work exactly the same: web services calls are used to download data to iPhone/iPad, and upload data to the server.
You'll need to consume new web services calls to download data and upload data.
We are near done with the Android version, so I can provide actual screen shots from the Android tablets/smart phones that perform the same function. Technical details will be provided after the project is awarded. I have worked with the same Android app programmer for numerous projects - if you do a good job, we'll be able to work together on many projects.
