elapsedDistance shows in simulator but not on device

can you update a datafield more than once a second?  If thats possible I can try the datafield route, otherwise its pointless.

By design, they update the screen every second if they are visible. (simple DFs handle this for you)

If they are not visible or not, compute() still runs every second.

Here's the doc that explains different app types

https://developer.garmin.com/connect-iq/connect-iq-basics/app-types/

so to me it looks like neither data field or app will do what I want.  The data field refreshes too slow and the app doesn't give me the access to data.

a device app will give you access to the data, but you need to do things yourself.  Recording device apps are more complex that DFs, but they can be done.

but is there a mechanism to update a data field early?  Can you run a timer and force an early refresh in the same way you can in an app?  I haven't seen examples of that yet. Once a second isn't useful for this.

How often do you want to update elapsed didstance in your device-app?

Its the speed that I am refreshing at 20fps.  The (non-working) distance I am only refreshing the distance variable at 1fps (although still redrawing the distance at 20fps)

20fps is going to take a big toll on battery, and the underlying data (elapsedDistance) won't be changing that fast be it a DF or a device app.

for vehicle use battery life isn't much of a concern.  Might be able to play with the number a little as I think I have some buttons unused but its going to be 10-20.  Would be surprised if i stop below 15fps.

If I could work out how to refresh the distance slower I would but the speed needs the higher refresh
