I have created other projects using the RedBear BLE boards (both styles) and Arduino interfacing to iOS, the most recent was a heart monitoring system, so I have a lot of experience with it. I can easily create the software, as well as the hardware, if needed. I already have everything here, except for the temperature sensors, so I can get it done quickly. I normally charge a lot more for my time, but I understand that, as a student, you can't pay as much as a company developing a health band. Still, I'm glad to help you create an impressive project. Let me know if you would like to discuss further.
