About
STAmina Apnea Trainer is the go-to mobile application for anyone looking to improve their breath-holding abilities — from recreational water sports lovers to competitive freedivers and AIDA-certified instructors. The app auto-generates O2 and CO2 training tables tailored to your current personal best and difficulty preference, adapting as you progress. During sessions, it can pair with compatible heart rate monitors and pulse oximeters to track your heart rate and blood oxygen saturation in real time, displaying the data in detailed charts to help you understand how your body responds to apnea stress and recovery. STAmina also enables contraction tracking with a simple double-tap during a session, allowing athletes to log and analyze the timing of diaphragm contractions over time. A highly customizable table builder lets users create bespoke exercises — apnea walks, pre-contraction drills, warm-up routines — by configuring rounds, durations, and repeats. Cloud sync keeps training history consistent across multiple devices, while Apple Health integration logs completed sessions as mindful minutes. Training reminders, voice guidance by a professional actor, and shareable exercise links make STAmina equally powerful for solo athletes and instructors managing students.
Key Features
- Auto-Generated Training Tables: Enter your personal best and choose a difficulty level; STAmina automatically creates O2 and CO2 tables matched to your current ability, updating as you improve.
- Heart Rate & Oxygen Saturation Tracking: Pair with a compatible HR monitor or pulse oximeter to capture real-time biometric data during sessions, displayed in charts for in-depth post-session analysis.
- Contraction Tracking: Double-tap the timer whenever you feel a diaphragm contraction to log its exact timing. Review contraction history and intervals to monitor progress and body awareness.
- Custom Table Builder: A flexible exercise constructor supports apnea walks, pre-contraction drills, warm-ups, and more — configure rounds, durations (time or tap-based), and repeats freely.
- Cloud Sync & Apple Health Integration: Create an account to sync your training data across devices; completed sessions automatically sync to Apple Health as mindful minutes.
Use Cases
- A recreational freediver uses auto-generated CO2 tables to systematically push their personal breath-hold record over several weeks of pool training.
- An AIDA instructor shares pre-configured training exercises with students via shareable links before an open-water session.
- A competitive spearfisher tracks oxygen saturation and contraction timing across training sessions to identify patterns and optimize pre-dive breathing routines.
- A yoga practitioner uses the Pranayama breathing table for structured breath-work and mindfulness practice, syncing sessions to Apple Health.
- A triathlete incorporates apnea walks and warm-up routines built with the custom table constructor to improve breath control during open-water swims.
Pros
- Beginner & Expert Friendly: Auto-generated tables adapt to any skill level, making the app accessible for casual water enthusiasts and competitive freedivers alike.
- Rich Biometric Insights: Heart rate and SpO2 tracking with chart-based analysis helps athletes understand physiological responses and optimize recovery between intervals.
- Highly Customizable: The custom table constructor and fine-tuning options give advanced users full control over their training design beyond standard O2/CO2 tables.
- Professional Voice Guidance: Audio coaching recorded by a professional actor lets athletes stay eyes-closed and focused during sessions rather than watching a screen.
Cons
- Biometric Tracking Requires External Hardware: Heart rate and SpO2 monitoring depends on purchasing a compatible HR monitor or pulse oximeter, adding extra cost and setup.
- Apple Health-Centric Integration: Health data sync is currently tied to Apple Health, leaving Android users without an equivalent fitness platform integration.
- Niche Use Case: The app is purpose-built for apnea and freediving training, offering little value outside of breath-hold sports contexts.
Frequently Asked Questions
O2 tables focus on progressively longer breath-holds with fixed rest periods to train tolerance to low oxygen, while CO2 tables use fixed breath-hold times with progressively shorter rests to build tolerance to carbon dioxide buildup — the main trigger of the urge to breathe.
No — the core training features work without any hardware. Heart rate and oxygen saturation tracking requires a compatible external HR monitor or pulse oximeter connected via Bluetooth.
Yes. You can configure an exercise and share it as a link directly with students or training partners in just a few taps, making it practical for instructors running group sessions.
The app is available on mobile platforms. Apple Health integration is specifically noted for iOS, so feature availability may vary between iOS and Android versions.
By creating a free account, your training logs and session history are automatically backed up and synchronized across all your devices so you never lose your progress data.
