## What is Apnea?

Your breath-hold is a number. Apnea measures it, then builds the training around it.

MEASURE FIRST
Start with one honest breath-hold. That number becomes your baseline, and every table in the app is scaled from it — not from a generic chart.

THE PROTOCOLS FREEDIVERS ACTUALLY USE
• CO2 tolerance tables — the hold stays the same, the rest shrinks. Trains your body to tolerate the urge to breathe instead of panicking at it.
• O2 tables — the hold grows, the rest stays fixed. Teaches your body to do more with less oxygen.
• Step-by-step holds, interval breathing, box breathing, pranayama.
All on dry land. All scaled to the number you measured.

TRAIN WITH YOUR EYES CLOSED
Voice cues call every phase. Haptics mark the transitions and escalate over the last seconds of a hold. The session keeps running with the screen off, so you can put the phone down and actually relax — which is the whole point.

DEEP MODE
The screen dims to almost nothing and the timer steps back. Sound and touch carry the session. Nothing moves, nothing glows, nothing demands your attention.

EVERY HOLD, IN WRITING
Personal best. Current streak. A 90-day trend you can actually read. The app remembers what you did so you can see whether it is working.

BUILT AROUND SAFETY, NOT AROUND IT
Dry land only. Never in or near water. Never alone in water. Stop at the first dizziness.
We removed the hyperventilation exercise this app used to ship, and we wrote an article explaining why: breathing hard before a hold does not add oxygen, it removes the warning that tells you to surface. That is the mechanism behind hypoxic blackout, and AIDA, Molchanovs and DAN all prohibit it.

TEN LANGUAGES. NO ADS. WORKS OFFLINE.

• Deep Mode dims the screen to almost nothing and lets sound and touch carry the session
• Every hold is logged: personal best, streak, and a 90-day trend
• Your plan is built from your own measured breath-hold, not a generic table
• We removed the hyperventilation exercise and wrote an article explaining why it was dangerous
