Tracking a ride/walk/run is ok - but boy does it take a long time to show you the results especially when looking at the map.
It's got to the point where I'll just export the gpx and use other apps - a major pain.
I have exactly the scene problem. I wonder if it is because I have been using this to log my rides for 4 years and my data base is getting too large. I agree with you that it has got so slow that out is unusable.
