Looking for an existing app or help in building an app for FitBit Versa 2 that would allow me to set a custom timer based on number of steps. Each time I go walk I may have a specific goal to walk x steps. Would like to be able to enter a step count and for the device to alarm when I have reached the halfway point in steps. This is different from my daily step goal - it is more like a mini goal for a given day and it might change each time I go for a walk depending on how many steps I have already taken.
Any guidance / tutorials that could help with such an app?
