Most of us open a breathing app at the exact moment we can least handle friction: before a presentation, at 2am, in a hospital waiting room. Too often the first breath comes after onboarding, a mood quiz, a sign-up and a trial offer. Deep Breath Plus starts in one tap, and gives inhale, hold and exhale each their own vibration, so you can follow along with your eyes closed or the screen off. Free, no account, records stay on your device. Some screens show ads, never mid-session.
