Charge 4 clock face SDK

[JupiterChris]

I have a Charge 4 but have poor near vision without reading glasses. I wish Fitbit had clock faces for people like me because it's not practical to put on readers while running or biking just to see my watch stats. Is there any way I can develop my own clock face? The available SDK doesn't list the Charge devices. Is there maybe a back way to do it if Fitbit won't support it or give us more readable clock faces?

Unfortunately the Device SDK only supports Fitbit OS devices. Have you looked in the gallery for alternative clocks? In the Fitbit mobile > Your profile > Charge 4 > Clocks > All clocks
