I know this might be unanswerable until the Apple Watch is released.

But does anyone know if there may be a way to determine the rough distance (in feet) between an Apple Watch and an iPhone?

    Can you explain why? It might help. – finneycanhelp Apr 02 '15 at 20:24

    If the Apple Watch appears as a bluetooth device, in theory you could [use the RSSI](http://stackoverflow.com/a/13466412/2446155) of the Apple Watch using Core Bluetooth to get the signal strength. But, there are [many factors](http://stackoverflow.com/a/3625388/2446155) other than _distance_ that could affect that reading. – Andrew Apr 02 '15 at 20:42

    Lol. Yeah. Put them right next to each other and watch the signal drop in half when you put your hand in the way. Not really any way to do it. – Fogmeister May 03 '15 at 14:31
  • You can only check reacablility of any of the device (iPhone or watch) using watchConnectivity. Check this link for Core Bluetooth http://stackoverflow.com/questions/18872366/objective-c-ios-6-ble-bluetooth-4-0-distance-calculation?lq=1 , it give information like RSSI(Received Signal Strength Indicator) – Muneeba Dec 14 '15 at 06:44

Currently, the WatchKit framework does not give you this kind of information, since third-party apps are still quite limited in what they can do. For example, they require a connection to the iPhone.

There is some speculation that later this year, third-party developers will be given more access to the hardware, e.g., bluetooth, accelerometer, pulse, NFC, etc.
