Suggestion: Simple start stop timer app

Hello Beamers!

I really like to race
More specifictly at the Nurburgring Nordschleife - Bridge to Grantry. But as things are now, I'm using my phone as timer, starting the timer passing below the bridge etc.

I think it could be real nice if af simple start/stop timer would be added

 

What about the Hotlap UI app? That should do what you're asking for

 

Havn't been able to get it working. Maybe it's because the start og finish is not at the same location.
