FAQ
Questions Breathing Timer owners ask.
- 01
How does the system ensure my timing is accurate for complex patterns like Wim Hof?
The query_breathing_parameters capability serves as the single source of truth, providing standardized component timings. This data feeds into calculate_single_cycle_duration, which ensures every cycle adheres to scientific standards before scheduling begins.
- 02
What if I want a session longer than the default time limits?
The generate_breathing_schedule capability accepts a custom totalDurationSeconds. It will proportionally scale and count down through all phases (INHALE, HOLD, EXHALE, REST) until the specified time is reached.
- 03
Can I customize the timings for a technique like Box Breathing?
Yes. The calculate_single_cycle_duration capability allows you to override default parameters, letting you specify custom seconds for inhale, hold, exhale, and rest phases.
