Intermittent fasting timer with program schedules and phase tracking

Most standalone fasting timers do not connect to nutrition data. That means users managing both calorie intake and fasting windows typically need two separate apps, which creates context switching and makes weekly reviews harder to interpret.

Calora keeps fasting inside the same product so the timer, the calorie log, and the weekly summary all belong to one consistent view of the day.

The fasting timer in Calora moves through five distinct phases based on elapsed time: Fed, Early Fast, Fat Burning, Deep Fast, and Extended Fast. Each phase reflects broadly recognized metabolic transitions that help users understand where they are in a fasting window.

Phase display is real-time and does not require manual updates. Progress through the phases is visible from the moment a session starts until it is completed or cancelled.

Calora includes a fasting program catalog with common protocols like 16:8, 18:6, and OMAD. Users can activate a preset or configure a custom fasting window. The active program drives the timer target without requiring manual entry each session.

Weekly schedule settings let users assign different fasting windows to specific days, which makes the feature more practical for people who eat differently on weekends or around training days.
