I’m a developer and I’ve built two Garmin watch apps for dry breath training and would love feedback from the freediving community.

Apps:

Breath Training Tool (Free)
https://apps-developer.garmin.com/apps/7190365c-13f5-4789-ba3e-1f1feac42409

BreathTraining System PRO
https://apps-developer.garmin.com/apps/12b88972-bc50-40c7-a138-e1e8d6f38068

Purpose & function:

Both apps are designed strictly for dry breath training (not underwater use).

They focus on structured breathing and breath-hold training such as:

  • CO2-style interval tables
  • O2-style interval tables
  • Static breath-hold training with PB tracking
  • Guided breathing / recovery sessions

The PRO version expands this into a full training system with:

  • adaptive progression based on performance and fatigue
  • readiness-based session recommendations
  • detection of plateau, decline, and overtraining patterns
  • CO2 tolerance, O2 adaptation, and recovery tracking
  • predicted personal best based on recent performance trends
  • structured training paths (CO2, O2, apnea, recovery, breathwork, etc.)

Feedback I’m looking for:

  • usefulness of training structure for real freediving dry training
  • whether progression/adaptation feels meaningful or overcomplicated
  • missing training modes or features
  • clarity/usability on Garmin devices (especially during training)
  • overall training realism vs simplicity balance

Availability:

  • Garmin Connect IQ (Garmin watches only)

Pricing:

  • Free version: free
  • PRO version: paid (single purchase)

Privacy:

  • no user accounts
  • no external data collection
  • all training data stored locally on the device

I’m actively improving both apps and would really appreciate any feedback from people actually training freediving or breath-hold disciplines.

Also open to collaboration with freediving instructors, coaches, or training groups.
