Question: Inaccurate Apple Watch reading
Apple Watch workout app gives a different inaccurate reading for outdoor run vs Nike app. I know it is inaccurate because I also use Fitbit and it shows similar readings to Nike app. Seems like the difference is only with outdoor run/walk compared to indoor run/walk. I have series 2 so I believe it does not require calibration but I still did it at the beginning. What should I do to get a more accurate reading?
P.S I have latest version of Apple Watch iOS.
Apple Watch Series 2, watchOS 4.1
