Breathe. Relax. Hold. All on your wrist, with your eyes closed. StatiQ is an apnea and breath-hold trainer with CO2 and O2 tables for dry static training on land, plus guided breathing and relaxation. Vibrations mark every phase, so you never have to look at the screen, and you train without your phone. BREATHE Even breathing, Box breathing and Energize (kapalabhati with a metronome and vibration). RELAX Longer exhale and 4–7–8 breathing. The four calm techniques run 1 to 15 minutes at a rhythm you choose, Energize 3 to 5 rounds of 30 to 120 s; all with live heart rate and stress, a history with stats and pages that explain how to do it and what it does. HOLD CO2 and O2 tables computed from your measured max with three effort levels (Light / Medium / High). The Ladder: calm breathing, a timed exhale and inhale cue, then holds that grow by 30 s per block, finished by an optional max hold. And the Maximum test. During a hold the watch shows the time and your heart rate; one page down shows stress, HRV (RMSSD), the last known SpO2 value and, while you breathe calmly, the breathing rate. SEE YOUR PROGRESS Right after a session you see your result: for tables the level, the hold and whether the table was clean; for the Ladder and the Maximum the change against last time and a new-record headline. One page down are the lowest and highest heart rate, stress, HRV, SpO2 and breathing rate. The activity is saved to Garmin Connect with laps and extra data fields. My overview shows breathing and relaxation over the last 30 days, your max over time, your personal records and the latest session of each mode. Analysis answers four questions on charts: Performance (max and tables), Body (heart rate, dive reflex, HRV), Training (how much and how often) and Next step. Tap any point of a chart to see its value and day; on watches without a touch screen, START shows a cursor that UP and DOWN move. THE PROTOCOL The structure is inspired by a small pilot study (Bezruk et al., Sports 2024, 15 participants): six dry holds of 30, 60, 90, 120 and 150 s with 60 s rests, the last one to your maximum, about 4 sessions a week. One deliberate change for safety: the study used hyperventilation between holds, StatiQ uses calm breathing. The effect of this variant has not been tested in a study. Track your last hold every session. SAFETY – READ BEFORE USE - Dry training only, lying down or sitting. Never in or near water, never standing, never while driving. - Energize (fast nasal breathing) can cause dizziness or fainting: sit down, stop if dizzy, and never hold your breath right after it. - Breath-holding can cause loss of consciousness. Do not train alone if you are unsure, stop at the first sign of discomfort, and do not use the app if you have a heart, lung or neurological condition, are pregnant, or have been advised against breath-hold exercise. - StatiQ is not a medical device. All values are informational only and not suitable for diagnosis, treatment or prevention of any condition. SpO2 is the last value the watch reports and may be minutes old. Requirements: Garmin watches with a round AMOLED screen (see Compatible Devices). Wrist heart rate required; SpO2 shown only on watches with Pulse Ox. Data: all data stays on your watch and in your Garmin Connect account; StatiQ sends nothing anywhere. Price: everything except Analysis is free. Analysis is free for 14 days from the first time you open it, then a one-time payment of 219 CZK unlocks it on that watch: the watch shows a code, you pay by card on statiqapp.pages.dev and get an unlock code to enter on the watch. Refunds: within 14 days of purchase on request by e-mail, even though the code has already been delivered; if you switch to another watch, you get a new code for free.

Smoother navigation: menus, settings and results open and scroll without stutter (storage reads are cached and preloaded after launch, menu rows are measured once). Finishing or leaving a breathing exercise responds right after the key press. The planned length of a breathing exercise is shown exactly.
