BLE Scanner App (iPhone) to measure distance -- 2

The app should do the following: 1. the app makes a URL request at startup (only once) and receives the names of the BLE devices to look for, 2. the app lists the names and their distance (similar to the attached image), 3. the app updates this list once a second (until the user closes the app), 4. if you have read all this, tell me what is five plus two, 5. this is just a first test, I will need more features later.
