Dynamic/Static Apnea Trainer is a configurable breath-hold interval trainer for Garmin watches. For dry training environments only. This app is not a safety device and does not replace qualified supervision, training, or appropriate safety equipment. Choose between two training modes: • Dynamic Apnea — interval-based dry-land breath-hold practice with preparation, hold, recovery, countdowns, sound, vibration, heart-rate display, and a session summary. • Static Apnea — configurable dry-land breath-hold tables. Set preparation time, optional Hyper/Hypo time, number of holds, starting hold duration, hold increase, recovery duration, recovery increase, and a maximum-hold safety reminder. Features: • Clear, full-screen countdowns • Sound and vibration cues at key times • Backlight during the final countdown • Adjustable training plans directly on the watch • Optional Hyper/Hypo phase after preparation • Heart-rate display when supported by the device • Session summaries with completed holds, duration, heart-rate information, and available oxygen-saturation information • Maximum static-hold safety reminder, set to 7 minutes by default Train conservatively. Stop immediately if you feel unwell, dizzy, or uncomfortable. Do not perform breath-hold training alone.
