I have been using Map My Fitness (MMF) and TomTom (TT) Multi-Sports Cardio for quite a while. I love my TT very much except for an irritating sync bug between TT and MMF. I will go into that some day. Today I have got my 38mm Apple Watch Stainless Steel with a black Sports band delivered. While everyone mentioned that the 42mm is small enough to fit everyone, I find that 38mm fits even better. It's probably that I have a small wrist. Unlike my Pebble, Apple Watch is so comfortable that I had never once take out from my wrist.

My post today is comparing the accuracy of MMF and Apple Watch. I ran a 3.2km route at my usual pace. Here's the result.

Result from MMF |
MMF recorded me running 3.28km at a pace of 5:52km/min.
 |
| Result from Apple Watch |
Apple Watch recorded me running 3.08km at 5:54km/min.
In terms of pace, they are pretty close. Let's check out the route. According to Singapore's OneMap measurement, it should be 3.28km.

| OneMap.sg measurement shows that my route should be 3.28km. |
Thus MMF is pretty spot-on on the distance. Strangely, both the MMF and Apple Watch are using the iPhone GPS, how can the distance be that different?
 |
| TT tracking from a previous run |
TT measured the distance at about 3.21km from a previous run. Both MMF and TT recorded a burn rate of about 201-202 calories while Apple Watch recorded a burn rate of 148 calories from the same distance ran.
So who's right?
My next run will be with TT and Apple Watch for a more accurate representation.
