iPhone application - Bluetooth Low Energy - BLE - graphing data from connected device similar to FitBit

Hello Freelancers, This project is for iOS developers who are familiar with the CoreBluetooth framework and bluetooth low energy devices. Summary: We would like an iPhone application developed that will sync with a bluetooth low energy / BLE / bluetooth 4.0 fitness device and graphically display stored data from this device. It will also recommend a fitness plan for the individual, with daily and weekly goals computed based on the user’s desired fitness plan intensity. We have written the firmware for the fitness device, and will provide the services and characteristics UUIDs and/or work with the chosen developer to modify the GATT structure. In addition to correct functionality that I will detail below, the entire application should graphically look good. A style that I am looking for would be similar to the "Details [login to view URL]" attachment. The FitBit app would also be a good source of inspiration. The chosen Freelancer should be great with communication. Regular status updates and prompt replies to questions are required. Detailed description of application requirements follow: The data that is received from the fitness device is essentially a collection of time stamps. The hardware is counting the number of times a user performs a certain action (for example, takes a step) and records the associated time this action occurred. The application should pull all the timestamps since last sync, store this information, count the total number of timestamps pulled, compute derived metrics based on this data, and do this in the background periodically even if the app is not in the foreground on the iPhone. In all screens, the desired text, number of buttons, layout of buttons, computed metrics, etc, may change. The attached screenshots are to represent an idea, not a concrete layout. This application is to be a tabbed application, with 4 tabs - home, details, me/user profile, and settings. When the user first opens the application, it will ask them a series of questions to set up a local user profile. These questions can be seen in image "initial [login to view URL]". The answers to these questions are saved to the local user's profile, and can later be seen in the Me tab. See “[login to view URL]”. It will then ask them to pair their fitness device, and the application will remember this device and automatically attempt to connect to it in the future when the application is opened, and during the periodic data collection mentioned above. The questions that the user answers during this setup will determine the daily and weekly goals the user will have. The goals are purely based on one metric, the number of timestamps per day. I can go into more detail about the goals after the Freelancer is chosen, but the idea is that the more timestamps the user accumulates per day, the worse they are progressing towards their goal. Lower is better. So in my example home screen “Main page”, the user’s goal was 50, but they are currently at 60. This is why the text is displayed red, and the bar graph shows green to yellow to red. The home tab displays the total number of timestamps for that day. It also shows a bar graph of that data in comparison to their goal, and some quick metrics at the bottom. These are all calculated metrics based on the one primary one, the # of timestamps. The details page shows detailed weekly graphs of the metrics by default. We would like the user to be able to see a detailed breakdown of any desired day, week, month, or year. We would also like the number of goals met out of the total days being displayed to be shown, and the total number of timestamps for that period of time. The graph should also be able to be changed to display the other calculated metrics as well. This can be seen in the images “details page”, “details page graph metric 2”, and 3. Settings page will allow pairing options for the connected device, and the ability to reset the collected data. Profile page was described above.
