STAmaster is the dedicated Static Apnea (STA) training companion for freedivers of every level — from beginners working toward their first 2-minute hold to competitive athletes chasing podium times.
PRECISION HOLD TIMER
Voice-coached breath-holds with real-time contraction marking. The high-precision timer continues running when your screen locks. Wrist haptics signal phase transitions so you can train eyes-closed.
CO2 & O2 TRAINING TABLES
Create fully custom CO2 tolerance and O2 adaptation tables. The app guides you through every round with audio cues and automatically logs each session to your history.
AI COACHING
A built-in rule-based coach analyses your session data and delivers personalised feedback after every session. Detect training plateaus, track CO2 tolerance trends, and receive actionable tips calibrated to your actual performance history.
PERSONAL BESTS & ANALYTICS
Every session is logged. Review your hold time history, PB progression, contraction onset trends, CO2 tolerance curves, and session volume over time in the Progress tab.
28-DAY TRAINING PLANS
Generate a personalised 4-week training plan based on your current PB, goal, experience level, and weekly availability. Plans use proper periodisation — foundation, CO2 focus, push, and integration weeks.
SUPPLEMENTARY TRAINING
Guided breathwork protocols, freediving-specific yoga flows, cardio sessions, and meditation exercises are all included — because STA performance depends on whole-body fitness.
HEART RATE & READINESS
Connect any Bluetooth heart rate monitor (Polar, Garmin, Wahoo) or Apple Watch for real-time HR during sessions. Morning HRV and resting heart rate from Apple Health power your daily training readiness score.
SAFETY FIRST
STAmaster enforces a mandatory buddy check before any wet static (in-water) session. The app will not start a water breath-hold without a confirmed training partner present. Freediving safety is non-negotiable.
WHAT IS STATIC APNEA (STA)?
STA is a competitive and recreational freediving discipline in which the athlete floats face-down and holds their breath for as long as possible. It is the foundation of all freediving performance and the primary target of breath-hold training.
REQUIREMENTS
- iPhone with iOS 17 or later
- Apple Health (optional — for HRV readiness score)

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Guest Mode: Hand your phone to a training buddy and time their hold without
mixing it into your own stats and PBs. Add their name, and guest sessions
stay tagged separately in your history.
• Interactive Timer Guide: New hands-on walkthrough teaches the core timer
gestures before you ever hold your breath: tap to mark a contraction,
double-tap to surface. Shows automatically for your first few sessions, and
you can replay it anytime from "How the timer works."
