FourBeat: Box Breathing

FourBeat is a focused, no-fuss app for box breathing — the 4-4-4-4 technique used by Navy SEALs, athletes, and anyone trying to settle their nervous system on demand. Inhale for four. Hold for four. Exhale for four. Hold for four. Repeat. That's the whole practice. FourBeat just gets out of the way and times it for you. — A single animated circle that grows, holds, shrinks, and holds in sync with your breath — Choose haptic, sound, or silence at each phase transition — Adjustable cycle count and pace (3–8 seconds per phase) if 4-4-4-4 isn't quite your rhythm — Pause and resume any time — Works fully offline. No account. No tracking. Nothing leaves your phone. Box breathing is one of the simplest ways to slow a racing mind, lower your heart rate, and shift out of fight-or-flight. A few cycles before a meeting, after a hard workout, or when you can't fall asleep — that's all it takes. FourBeat is free, has no ads, and never asks you for anything.
