Comparing IF Schedule Effectiveness

Use the plan comparison feature to decide between popular schedules like 16:8 (best balance) and 20:4 (higher fat burn) before committing to a daily routine.

Once you start the timer, the app actively tracks your progress and clearly indicates the exact moment your predetermined eating window opens based on your selected fasting plan.
