App/field for walking baby stroller

Hey everyone,

Here is a programming idea for you.

My problem is walking a baby stroller does not  give nearly an accurate step count, or usually only showing 1/3 or 1/4 of the "should have been" total.

Would it be possible to create a device app and have it generate "fake step" count by using GPS location and a hard set step length, or a calculated average from last walk/hike and just do 1km == ca. 1500 steps or something similar, and add that to the current day total? (while using the app, disable the natural step count to not get double).

This should have been something Garmin offered a long time ago Disappointed

Best regards
