iPhone Xcode/Swift or Xamarin app

I have attached a PDF of this project. Please download it and check it out for all the information you will need to know about this project in order to make a intelligent bid. Note that the project looks large but it is not. I'm just very detailed about what all goes on in the app so that the freelancer (you) has a lot of knowledge of what it is i am looking for the app to do. I'm really looking for an Xamarin version but if you are better at native Xcode (or swift) then by all means code it that way. Note that this app will not be needing to be placed into the apple store for download. It will only be used for personal use. I would like to keep this project under $110. NOTE that you will need to know how to send and receive Bluetooth data to and from an arduino in order to complete this project. Bluetooth module used is a HM-10 Bluetooth 4.0 LE module. Arduino code has been completed by me. Just need to interact with the iPhone. Please read the PDF carefully from start to finish before posting a bid. If during the first 20 minutes i get a lot of bids then i will just ignore them as it wouldn't be enough time to examine the PDF in it's entirety and you would just be wasting my time.
