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.
