A-5: Yes. Version 2.1 introduced an option to integrate with the bluetooth Wahoo Fitness scale. For now, this works only with iPod 4th generation and above, iPad 3rd generation and above, iPhone 4S and above and mini iPads. You will need to have bluetooth enabled on your device (without pairing) and from within the app, enable Wahoo integration from Advanced Settings (scale needs to be within bluetooth range for initial setup). You will then need to map your current profile with either an existing profile on the scale, not map at all, map to any profile on the scale, or to simply copy an existing profile to the scale and map it with that. You may do the same for each of your existing profiles. Upon running the app while the scale is within range, the app will update the weights for all the profiles based on this mapping. Furthermore, if the scale is within range, you may also hop on the scale and observe the weight on the scale from within the app while it gets recorded (if mapped).
