Hello @DelPi
The Ice Cream clock face might be a good one for you.
The only real problem with it is the deliberately 'out of focus' style. But it displays the steps in a really big way.
You can get it by tapping your profile picture on the Today screen in the App on your phone. Then Charge 5, tap. Tap on Gallery, tap on Clocks at the top, then you can look at the clock faces and choose one you like.
Install, then sync your Charge 5.
I hope that helps to solve your problem.
Edited to add: Sorry I might have misread the screenshot. That might be the time, not the number of steps! In which case, the ring is showing how far along your progress is.
