Week7 run 2 and confusion hits in!!

[Mallard1981]

Well went out for run 2 of week 7 and looked at the time I set. Same route for the last 5 runs and each one my time has improved but the distance has changed. Last night it tells me I did 5.37k in 31 min but Monday it said 5.7k in 32 min. When I looked back at the others they were all different distances. However I know it's the same route lol. So what I'm asking is what do people use in the way of apps or gadgets to get accurate distance and time measurements
