Lull is the shortest health app in the world. Open it. Breathe for 60 seconds. Close it. That's the entire app. No onboarding marathon. No subscription. No library of content you'll never use. Lull does one thing: guides you through 60 seconds of breathing, once a day — then gets out of your way. — 5 BREATHING TECHNIQUES — A different technique rotates in automatically each day, so you never have to decide: • Square Breath — 4 in · 4 hold · 4 out · 4 hold. The baseline. Used by everyone from athletes to surgeons. • 4-7-8 Breath — Inhale for 4, hold for 7, exhale for 8. Resets your nervous system in seconds. • Deep Sigh — A double inhale followed by a long exhale. The fastest way to offload stress. • Coherent Breath — 5.5 seconds in, 5.5 out. Puts your heart rate variability into a natural rhythm. • Power Breath — Fast cycles followed by a hold. A light version of the Wim Hof method to build energy. — JUST BREATHE — The animated circle expands as you inhale and contracts as you exhale. Gentle haptic pulses mark each phase change. No thinking required. — STREAK — The only metric that matters: how many days in a row did you show up? Lull tracks your streak and lets you share it — without looking like an ad. — NATIVE — • Logs every session as Mindful Minutes in Apple Health • Daily reminder at whatever time you choose • All data stays on your device — no account, no cloud, no tracking Lull wants you to close it.
