Works well, could look a bit better. I've recorded a couple of rides and it seems every now and the the mph go down to 3mph for about 60 seconds then goes back to the actual mph. I used Waze and Geo Tracker to watch the replay and both apps had the issue with the 3mph. Other than that, the app works.
Does the job, exactly what I needed.
Well worth the money. Tried some other GPS mock location apps but they were either difficult to use, did not support moving along a track or route, or crashed.
Some rough edges but support is very responsive.
