Review summary

Most reviews praise UsA Scalar Black for readability and visual appeal, noting its beautiful, clean design and suitability as a daily driver. However, several users report compatibility issues on Galaxy Watch Ultra and problems with health data (HR not updating or live), along with occasional navigation problems from the watch face. Overall, the face is highly attractive and well-liked, but reliability on some devices and data features needs improvement.

Pros

Excellent readability/legibility.
Beautiful, clean, and eye-catching design.
Highly regarded as a daily driver / favorite watch face.
Useful for health metrics.

Cons

Incompatibility with Galaxy Watch Ultra / installation issues.
Heart rate data is wrong or doesn't update.
On-click navigation to required apps sometimes doesn’t work.

2024-10-10	Jo*****	Great looking watchface and since it only comes in black even AOD mode could not be ruined because it just stays ... black! Dev got lucky this time I guess. 😉 Anyway, I recommend this specific black version of the watchface to all AOD fans.
