ApneaMode

O2/CO2 tables, static apnea, square breathing, and apnea walks — with voice cues, history, and optional cloud sync.

Apnea Mode is a dry-land training companion for breath-hold practice: static apnea, breathing tables, and apnea walks.

WHAT’S INSIDE

• Static apnea — O2 and CO2 tables, progressive and custom protocols, plus single max-hold sessions • Square breathing — a 4-phase cycle for warm-up and recovery • Apnea walk — breath-hold walking with distance tracking (location permission only while you train) • Timers — stopwatch and countdown • Voice cues that keep working with the screen locked • Local training history; optional account for cloud backup and sync

WHO IT’S FOR

Freedivers, divers, and anyone building a structured dry-land breath-hold practice.

SAFETY

Apnea Mode is a training aid, not a medical device, and not a substitute for a qualified instructor. Never train in water alone. Stop if you feel dizzy, unwell, or unsure, and seek professional advice when needed.

ACCOUNT

You can train as a guest. Sign in with email, Google, or Apple if you want cloud backup and cross-device sync. Account deletion is available in the app.
