Atmea

The App

What Atmea can do

Eight building blocks for structured breath and apnea training — from freeform exercises to an adaptive weekly plan and a data-driven coach, right through to the link with your sleep data.

The app launches on iOS in October 2026. The Android version follows by November 2026.

Exercises
Build your own multi-phase breathing exercises from any number of blocks — inhale, hold, exhale, breathe — with a progressive change per round, a preview before you start, voice cues, and optional background music.
Training
Five fixed tables for apnea training: CO2, O2, pyramid, the one-breath table as an intense CO2 variant, and the no-contraction table with guided coherence breathing. You mark the struggle phase with a tap — with no-contraction you rate the session yourself from 1 to 10 instead. Automatic diaphragm-contraction counting can be switched on (beta).
Training plan
A rule-based weekly plan in four levels — from beginner to a freely arranged custom week. The Today block starts the session that's due with a single tap; weekly progress, streak, and catch-up suggestions are derived continuously from your history. Every rule is disclosed in the app with its source.
Coach
Suggests adjusted training durations — from your maximum attempts and struggle trends, for the CO2 table even without a current maximum attempt, and for the no-contraction table from your series of ratings. Never applied automatically, you decide.
Maximum Attempt
A guided maximal breath-hold test with a relax and an apnea phase — duration and struggle time are recorded.
BOLT Test
A standardized Body Oxygen Level Test per the Buteyko method: a rest phase, then holding until the first noticeable urge to breathe — deliberately not a maximal effort.
Dashboard & history
Three dashboard pages: statistics blocks, an activity journal as a daily timeline, and a sleep page that puts training and sleep side by side. Reorder or hide blocks freely — and every table, every maximum attempt, and every BOLT value has its own history view as well.
Sleep & training
See how your training and your sleep interact. Only with your permission does Atmea read your nightly sleep values from your device's health service (Apple Health or Google Health Connect) — sleep duration, deep sleep, REM, pulse, heart-rate variability (HRV) and respiratory rate (a sleep-tracking device such as a watch or ring required) — and set them against your sessions: sleep score and hold time over time, plus the “What works for you?” view that compares calm and demanding evenings. Deliberately framed as observing relationships — access is read-only, and all values stay locally on your device.

And also

Guided session

“Calm and relaxation”: about ten minutes of narrated breathing with a breathing orb, pause, and section skips.

Backup

Export all your data to a file and restore it later — optionally AES-256 encrypted with a password.

Language & voice

German, English, French, and Spanish; two narrator voices with audio previews and two music beds.

Appearance

Light and dark colour scheme — optionally following your device setting.

How it works

  1. 1

    Pick an exercise, build your own — or let the weekly plan set today's session

  2. 2

    A phase timer with voice cues guides the session

  3. 3

    Deliberately save or discard the result — nothing is auto-saved

  4. 4

    History and trends feed the dashboard, your plan progress, and coach suggestions

Important safety notice

All exercises in this app are intended exclusively for dry, on-land training. Always perform them in a safe environment — lying down or safely seated.

Before training:

These exercises assume a healthy general condition. If you have respiratory, cardiovascular, or other pre-existing conditions, only perform them after consulting a doctor.
