Your box breathing space
Box breathing is one of the most effective techniques for calming your nervous system. This app makes it simple — custom interval and session length. No ads. No noise. Just breathe.
Perfect for... anywhere, really
Four phases. One steady rhythm. Real calm.
Box breathing (or four-square breathing) is simple: inhale, hold, exhale, hold — all for the same count. That even rhythm helps lower stress, steady your heart rate, and bring your focus back in minutes.
Practice it regularly and it becomes a reliable reset you can use anywhere — a few minutes a day is enough.
- Inhale · breathe in through your nose
- Hold · keep the breath in
- Exhale · release through your mouth
- Hold · stay empty before the next breath
Rooted in science. Simple in practice.
- Activates the parasympathetic nervous system — your body's rest-and-digest mode
- Reduces cortisol and perceived stress
- Improves focus and decision-making
- Lowers heart rate and blood pressure
Built for focus, not features.
Box Breathing Space is a free, ad-free progressive web app — no account, no notifications, no noise. Set your interval, set your session length, and breathe.
You can add it to your home screen for instant access, just like a native app.
