Breath Training System - Garmin Watch App

[Bitochi_garmin]

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)

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.
