Is anyone interested in converting a Fitbit app to a Connect app?

What is the added value of the app you want to converter? any default Garmin sport can do ti?

What is the issue you have?

I am looking for a simple app that focusses on total time and total laps.  I know how many laps-per-mile the indoor track is.  What I like is something that gives me a large total time and a large total laps (so that an old blind guy can read it mid-stride).  The Garmin app focusses on individual lap times. 

I have attached an image of my start screen for reference.  Curr and Prev refer to individual lap times.  The single zero is lap count and the 4 zeros are total time.  The Curr and Prev, along with a scrolling summary screen at the end, were added per other users request.

Current lap time / previous lap time / total time and current lap are data fields that can be set in custom screens data. 

For the font size, create 2 screens data (one with cuurent and previous lap, one with lap and total time), the font size will be big. Have you tried?

I have not yet.  I am still trying to teach myself the Garmin monkey language.  I am not a professional programmer, so it is taking me a while to figure out. 

Look at how to configure data fields within an activity.  As Juggus suggested, you can just set up screens with native data fields to see what you want - no programming required.
