Before you start
Why five minutes on your breathing is worth it
Gets you through stressful moments
A short breathing pause can help you slow down and reset during a demanding workday — a rough meeting, a tight deadline, an urgent issue.
Helps you switch off after work
Screen time doesn't come with a natural stopping point. A few minutes of paced breathing helps mark the transition out of work mode.
Keeps you steadier all day
Long periods of focused work can make you less aware of how you're breathing. BreathCheck gives you a simple way to pause and check in.

What do you need right now?
You shouldn't have to think "I want to practice a breathing technique." Just match the moment you're in:
Your breathing may be different from what you expect.
Long stretches at a screen change how you breathe without you noticing — fast, shallow, or tangled up in stress patterns that are easy to miss on your own. The check looks at three simple aspects of your breathing: resting rate, breath control, and paced breathing.
Want to skip straight to practicing instead of being scored? Jump to the exercises.
- 1Resting rate
Count your breaths for 60 seconds, sitting normally.
- 2Breath hold control
One relaxed hold, stopped at the first urge to breathe — not your max.
- 3Box breathing
Four rounds of a paced 4-4-4-4 rhythm.
Guided practice
Breathing exercises
The test above gives you a score. These are what you actually practice — no scoring, no timer pressure. Pick the one that matches what you need right now:
Box breathing
Four seconds in, hold, out, hold. A steady, even rhythm that's easy to learn and good before anything stressful.
4-7-8 breathing
Inhale for 4, hold for 7, exhale slowly for 8. A longer exhale that's widely used to settle the body before rest.
Slow, steady breathing
An easy, even rhythm with no holds — just smooth in, smooth out. Good for keeping a good baseline steady.
Diaphragmatic breathing
Breathe naturally at your own pace — notice your belly rise and fall. No need to force it or breathe deeply.
Extended exhale
A comfortable inhale followed by a slightly longer, relaxed exhale. A simple option for tense moments or after a difficult meeting.
Bedtime wind down
A longer, dimmed session with a soft ambient tone that breathes with you. Pick 3, 5, or 10 minutes and let it run.
Box breathing
A steady, even rhythm.

How do you feel now?
Your breathing snapshot blends two things we actually measure: your resting breathing rate and a gentle breath-hold control check. The guided breathing round at the end is practice — it isn't scored.
It's a self-guided trend indicator to help you notice patterns over time — not a medical or diagnostic measurement.
BreathCheck is not designed to assess sudden or severe breathing problems. If you're having severe difficulty breathing, chest pain, fainting, or blue or grey lips, seek urgent medical care now.
This tool offers general wellness information and self-guided practice, not a diagnosis or medical advice.

Stage 1 of 3
Resting breathing rate
Sit comfortably. Tap the button once for every full breath (in and out counts as one) for 60 seconds.
Why: this gives us a baseline for how quickly you're breathing while relaxed.
Stage 2 of 3
Breath hold control
Breathe normally, then let a normal exhale happen and hold. Stop at the very first urge to breathe — not your maximum. This is a control test, not an endurance test.
Before you hold
- This is a gentle control check, not an endurance test.
- Never hyperventilate before holding your breath.
- Stay seated. Don't do this in water or while driving.
- Stop immediately if you feel dizzy, faint, or unwell.
- Don't try to beat a previous time — that's not what this measures.
Stop as soon as you feel the first urge to breathe, a swallow reflex, or your throat or belly contract.
Stage 3 of 3
Box breathing
Follow the lungs. Four seconds in, four second hold, four seconds out, four second hold. Four rounds.
This is a short guided practice round — it isn't scored, it's just practice following a rhythm.
