Long-term tracking with a 12-hour timer

A 12-hour timer is rarely used for active focus; instead, it's a background tool for health, cooking, and long-term deadlines, tracking exactly half of a complete day.

Popular use cases

Tracking the fasting window for intermittent fasting (e.g., 12/12 or 16/8).
Marinating meats or resting dough overnight.
Setting a hard deadline for the end of the day.
