Free Guided Breathing App for iPhone · Ad-Free & Private
Free, guided breathing to help you sleep, calm down, and focus — private and ad-free.
Choose how you want to feel and breathe along. No streaks to stress over, no leaderboards, no gamification, and no notifications you didn’t ask for.
Instead of memorizing ratios, select your goal: Sleep (4-7-8 breathing to wind down), Calm (long extended exhale to soothe anxiety), Focus (box breathing to center), or Just Breathe (coherent breathing for an easy, balanced rhythm).
Follow a soothing pulsing orb or a scrolling breath curve with a glowing ball. A gentle count-in, soft iPhone haptics (vibration), and an optional recorded voice cue each inhale, hold, and exhale so you can rest your eyes.
Overwhelmed? Use the one-tap Reset (physiological sigh) to calm down fast in under sixty seconds — or launch straight into a Reset from your Lock Screen or Home Screen widget.
Build custom breathing patterns for your personal lung capacity, set an optional local daily reminder, and view a calm, non-competitive history of days breathed and minutes.
No account, no sign-up, no ads, and no tracking. Bibo makes zero network connections — everything stays locally on your iPhone under the Apple App Store label Data Not Collected.
Every breathing pattern in Bibo is grounded in proven physiology to help regulate your autonomic nervous system.
A double inhale followed by a prolonged, unhurried exhale. Known as the physiological sigh, it is the fastest science-backed way to reduce acute stress and lower your heart rate in under a minute.
Inhale quietly for 4 seconds, hold gently for 7 seconds, and exhale slowly through your mouth for 8 seconds. This classic evening rhythm calms racing thoughts and prepares the mind for deep sleep.
Lengthening your exhale relative to your inhale stimulates the vagus nerve and activates your parasympathetic "rest and digest" response, helping you unwind whenever tension builds.
Equal-length inhale, hold, exhale, and hold (often called square or tactical breathing). Widely used by high performers and meditators to heighten clarity and ground the nervous system.
An easy, balanced 5-to-6 breath-per-minute rhythm with no retention holds. Optimizes heart rate variability (HRV) for everyday calm and gentle equilibrium.
Customize your own inhale, hold, exhale, and rest durations to match your personal lung capacity or specific mindfulness practice.
Bibo is designed for relaxation and general wellness. It is not a medical device and is not a substitute for professional medical advice. Stop immediately if you feel dizzy or unwell, never practice breath-holding in or near water or while driving, and consult a doctor before practicing breathing exercises if you are pregnant or have heart, lung, blood-pressure, or seizure conditions.
