Hi lads,
I have just bought a Digifob and downloaded the free companion to view activity. After doing all this my PC wont open the file. Can anyone point me in the right direction.
Thanks in advance
Gary. 
Would love to help BUT read my tag line! Really haven’t a clue what you are on about.
Sorry.
Does your employer use Tachomasterâ– â– ?
If so ask them for a workers log in, then download the app & it’s all there to see from your phone
