Natsoft VS Samsung note 3 with Race chrono application


I wanted to see how accurate the mobile phone GPS lap timers are. So I decided to use a Note 3 that had a pretty eventful Anzac day...

I have used it previously on a practice day, really put together a few solid laps and looked down only to see it turned itself off or something silly.


My conclusion is they are very accurate, but unreliable. I wouldn't invest in a mobile phone GPS lap timer set up, but if you have a cracked unused phone laying around its better than nothing.

Here are the numbers
