The latest major update resulted in a negative user experience, evidenced by a 0.73 star decline in average rating. While visual adjustments to contrast and legibility received praise, technical regressions in calculation logic and application stability currently dominate the feedback. The net impact is negative as these functional errors overshadow the intended feature additions.

This app has been updated by Apple to prepare for watchOS 27 compatibility. No new features are included.
