Galaxy Fit Watch Face Studio

I was wondering if there is any software to design faces for Galaxy Fit (SM-R370)?
The Galaxy Watch Designer only works for the smart watches but not for Galaxy Fit.

Or is there any other way to add or edit its faces?

Solution:
Galaxy Fit is running FreeRTOS and its not supported by any GWD version.
Older GWDs support SM-R360 or SM-R365. The new bands are not supported (never were).
