Design UI for existing menstrual bleeding app

Closed - This job posting has been filled and work has been completed.

Job Description

I have designed an app for research purposes.
We made an app to keep track of daily blood loos for a gynecology study.
The app exists and runs just fine. But, the interface is sloppy and poorly designed (https://itunes.apple.com/nl/app/id822202894?mt=8&affId=1860684)

Now we will make a new variation of this app for another study. But this time I need someone who can redesign the User Interface and make the app look more professional. It's designed for iPhone and Android.

The original designes are in powerpoint attached, I have them also in a sloppy photoshop file. I need the design preferability in OmniGraffle so I can continue to work on it myself.
We can re-design this app, and make perhaps some minor color changes for the new version. The app is in English and Dutch. We can work on the English version, I will translate into Dutch myself.

The icons for tampons , pads and pain indicator are more or less universal for this kind of research.
