Field notes

The session view is organized around the active phase, remaining time, and next step, with pause, skip, and stop controls available during training. Users can recalculate a full sequence while editing its parameters, calibrate tables from a personal best, and overlay live saturation and pulse when a compatible Bluetooth sensor is paired. The site also includes dedicated safety guidance for walking-based apnea practice.
