About this app

Box Breathing & Deep Breathing

A breathing app for box breathing, deep breathing, and four
more breathwork techniques. Start your first session in ten
seconds — no courses, no sign-up, no clutter.

Box breathing (4-4-4-4) is the technique Navy SEALs use to
stay composed under pressure. Four counts in, four to hold,
four out, four to hold. It is simple enough to do anywhere,
and it works because slow paced breathing settles the body
down on its own.

THE BREATHING EXERCISES

Box Breathing (4-4-4-4) steadies you before a meeting, an
exam, or any moment you need to think clearly.

4-7-8 Breathing is the one to use at night — a long exhale
that helps you wind down and sleep better.

Coherent Breathing (6-6) is slow, even breath work that
balances your nervous system and improves HRV.

Wim Hof Method is energising breathwork for clarity and a
sharp start to the morning.

Triangle (4-4-4) is a simple rhythm for anyone new to
breathing exercises.

Deep Relaxation (4-7) uses an extended exhale to relax the
body and quiet a busy mind.

Custom Timer lets you build any pattern you like — set your
own inhale, hold, and exhale.

A BREATHER COACH IN YOUR POCKET

The app guides every count so you never have to think about
timing. An animated circle expands and contracts with your
breath, haptic feedback marks each phase, and voice cues let
you practise with your eyes closed. It works like a breather
coach that is always available and never talks over you.

FOR ANXIETY AND STRESS RELIEF

Anxiety and stress show up in the body before you notice
them in your head — a tight chest, shallow breathing, a
short temper. Deep breathing is the fastest way to interrupt
that loop. When anxiety spikes, a few slow rounds calm
racing thoughts and bring you back to centre.

Keep the app on your phone for the moments you need stress
relief fast — before a difficult call, after a long day, or
any time you need to relax.

FOR BETTER SLEEP

Cannot switch off at night? The 4-7-8 method and other slow
breathing exercises quiet the mind and prepare the body for
rest. Run a session in bed and drift off without scrolling.
Many people use it as a nightly habit for better sleep.

EASIER THAN SITTING STILL

If you have tried relaxation techniques and found it hard to
sit with your thoughts, breath work is an easier way in.
There is nothing to learn and nothing to follow — just a
rhythm to breathe along with. Two or three minutes is enough
to feel calmer.

WHY IT WORKS

Slow, paced breathing activates the parasympathetic nervous
system — the body's own relaxation response. A few minutes
can lower your heart rate and shift you out of
fight-or-flight. These techniques draw on established
breathing practice and modern breathwork used by athletes,
coaches, and sleep specialists.

DESIGNED TO STAY OUT OF THE WAY

All six techniques are unlocked. Two calming visuals, dark
and light themes, streak tracking, daily reminders, and a
respiration counter. Fully offline, no account required —
your sessions stay on your device.

No courses. No voiceovers. No social feed. Just your breath,
guided.

A calm mind is one breath away. Start your first box
breathing session in ten seconds.
