Hi, I've been suspicious about the accuracy of timings in the ios app. I did w5 d2 tonight (walk 5, run 8, repeat) and the walk seemed lengthy, the runs seemed to go on and on.
Once home I reset my iphone and started the app again and timed the steps... The 5 min walks wend for nearly 7 mins, the 8 min walks for nearly 10....!?!? Anyone else had this?? VERY disheartening when you've been running for what seems an age and you check your timer and only 3 mins have elapsed according to the app
