## What is Box Breathing?

Box breathing, guided in real time. Follow the expanding box, breathe with the rhythm, and feel your nervous system settle in a few slow cycles.

Most breathing apps bury the technique inside long meditations. BreathBox does one thing well: it paces your inhale, hold, exhale and rest with a calm animated visualizer, gentle haptic taps and soft chimes — so you can close your eyes and just breathe, no reading required.

WHAT YOU GET
- A live box visualizer that grows and shrinks so you always know when to breathe in, hold, and let go
- Proven patterns built in: Box 4-4-4-4, 4-7-8 for sleep, Calm Down, Energize, and Coherent 5-5 resonance
- Gentle haptic cues and soft tones that guide each phase, so you can practice with your eyes shut
- Set your session length in minutes and let the timer run the full cycle count for you
- A calm streak, total minutes and full session history that keep you coming back
- An after-session mood check so you can watch your calm trend build over the week

PERFECT FOR
- Anyone who wants to slow a racing mind before bed or a big moment
- People managing everyday stress and anxious spikes
- Focus and reset breaks during a busy work day
- Beginners who want structured breathwork without a long course

WHY NOT JUST HOLD YOUR BREATH AND COUNT?
Counting in your head keeps your mind busy and the timing drifts. BreathBox holds the rhythm for you with visual, haptic and sound cues, so you can actually let go and let the pattern do the work.
