One Breath is free to download, and the free version isn't a stripped-down trial — Calm breathing works fully, for as long as you want, at no cost. WHY ONE BREATH IS DIFFERENT Most breathing apps ask for a monthly subscription before you've taken a single breath. One Breath never will. If you want Box breathing and 4-7-8 breathing too, unlock both together with a single $1.99 purchase — once, ever. No subscription, no recurring charge, no free trial that quietly turns into a bill. Most breathing apps want an account. One Breath doesn't have one. Nothing to sign up for, nothing to log into. Most breathing apps quietly collect usage data behind the scenes. One Breath collects none of it — no analytics, no tracking, no network connection of any kind. Nothing about your sessions ever leaves your phone. THREE TECHNIQUES, GUIDED BY TOUCH Calm breathing is free, always. Box breathing and 4-7-8 breathing unlock once for $1.99. Choose a session length from 30 seconds to 3 minutes. A soft, expanding circle shows you the rhythm on screen, and gentle haptic feedback lets you feel each phase — so you don't have to stare at your phone to follow along. ONE PURPOSE No streaks, no badges, no notifications asking you to come back, no feed to scroll, no ads — ever, free or unlocked. One Breath does exactly one thing, and it does it the moment you open the app: it helps you take a breath.
