Tracks Logger Pro

It does what it needs to do. Tracks and records position accurately. It’s nice that it also supports NMEA export. But the UI is so terrible I can’t I spend more time trying to use the product that it’s worth. Other trackers are slightly more expensive but way easier to use.

I race autocross, and this app allows me to map the track while I walk it before racing. One issue that I found is that the first few points are always way off because gps hasn't yet stabilized. To fix this, I usually start the tracking, stop it and discard the track once gps is stabilized, and then start tracking again. Another suggestion to the developer is to omit the degree symbol in the output. I have to remove it in Excel before I can plot the data. Otherwise, it works great!
