I would like to be able to mod my FitBit Charge 3

[ThomWBlairIII]

I'm brand new to all things FitBit, but I'd like to mod my FitBit Charge 3's functioning, like changing how the weather app comes up. My Dad wishes his Charge 3's weather app could come up quickly instead of having to swipe through so many screens.

Also, he'd like the clock to stay visible for several seconds longer before disappearing.

Is there any way to mod a Charge 3 to make these changes?

No Fitbit devices allow changes like those. Ionic and Versa can run other apps, such as clocks that stay visible for longer, but Charge 3 cannot.
