A real reboot for your mind iZen is an offline three-layer recovery toolkit built for long-term mental fatigue. It is not a passive meditation audio player or a read-only article app. When stress hits, breathe within 90 seconds, mix a soundscape, or take a one-minute check-in. Lasting pressure drains more than willpower. Recovery means lowering what drains you and raising what restores you. Three layers, so you always know what to do now and why it helps. LAYER 1: QUICK RESET For moments when fatigue spikes, your heart races, or your mind goes blank. - Breath Workbench: 4-7-8, box breathing, physiological sigh, resonant patterns. Orb and box layouts. Ink wash and luminous themes. Spoken guidance, eyes-closed haptics that can dim the screen, cue tones, Zen mode, and Live Activity. - Guided player: SOS, grounding, acupressure, and mindfulness in timed steps. Pause, back, skip, +30 seconds, optional voice and soundscape. Lock Screen follows the step. - Soundscape Mixer: rain, ocean, stream, wind, fire, pink noise, brown noise, bowls. Made on device. Presets for focus, calm, sleep, and SOS. - Grounding 5-4-3-2-1, acupressure, emotional SOS, and NSDR-style rest. LAYER 2: DAILY REBUILD Five to fifteen minutes a day. - Mindfulness, focus, and sleep rhythm. - Movement for BDNF, steady blood sugar, hydration. - Mood journal with emotion, intensity, filters, sorting. After saving, on-device insight (Apple Intelligence or local rules) names a feeling, a need, and one next step. Crisis language opens grounding and help. LAYER 3: ROOT RELIEF Reduce sources that keep draining you. - Three must-dos per day to fight decision fatigue. - Meal, outfit, and schedule templates. - Boundaries and emotional labor. - Cognitive reframe: situation, thought, evidence, a balanced view. The same reading can follow, including a look back over the week. DAILY ZEN: 500 ANCHOR LINES One stable line per day on Home and widgets. Shuffle anytime. Five themes: calm, release, focus, sleep, compassion. Shareable Zen cards. SCIENCE LIBRARY: 17 ARTICLES Five categories: breath and nervous system, cognition and recovery, body rhythm, work and emotion, product principles. Takeaways, evidence levels, practice links, and a non-medical note. CHECK-IN AND HOME One-minute check-in for sleep, task load, or people drain. Recommendations stay local. The recovery score uses only real signals: recent sleep, an on-device mood, optional HRV and resting heart rate versus your baseline, and this week's mindful minutes. Six ten-second moods on Home, a widget, or Siri: Calm, Anxious, Tired, Angry, Low, Bright. Low battery, Needs a reset, Steady, or Replenished points to a layer. Until a signal arrives, the score stays blank on this device. FAVORITES AND ZEN LISTS Star practices and quotes. Custom Zen Lists for commutes, bedtime, or SOS kits. SEARCH AND BROWSE Local index for practices, quotes, and science. Search tab on iOS 18 plus. Three-layer guide cards. Deep links such as izen://browse/instant for Shortcuts. CRISIS HELP Helplines for 30 plus regions: locale preview, phone, SMS, and web. Open from Home or the SOS widget. Reference only, not medical advice. SYSTEM INTEGRATION Widgets: Daily Zen, Quick Breathe, streak, SOS, mood, and three must-dos. Lock Screen and Control Center (iOS 18+). Siri logs a mood, starts a practice, or reads today's line. Optional HealthKit: mindful minutes, State of Mind, sleep, HRV, resting heart rate. Body signals stay on device. Optional iCloud and reminders. Spotlight off. On iOS 26, the top edge softens to a quiet blur. EXPERIENCE AND PRIVACY English, Simplified and Traditional Chinese. Themes, accent colors, alternate icons. iPad and VoiceOver. Offline-first, no account, ads, or analytics. Data on device unless iCloud is on. Educational tools only, not medical care. iZen 1.2.0 adds a recovery score that waits, guided steps, eyes-closed breath, and a quiet reading of what you wrote. Stop for a moment. Your nervous system deserves care.

I made this breath work app to memorialize my mother, Eirene — named after the Greek goddess of peace. The fundamental sessions in this app will always be completely zero-cost, ad-free, function without any need to create any accounts, and will never track or sell people's information in any way. Because I hate all that stuff. Guided tummo breath work exercises for beginner, intermediate, and advanced practitioners. Open the app, pick one, go. On-screen animation with optional haptic cues that guide each breath, so you can practice with your eyes open or closed. It features a pre-session safety guide that precedes each session to remind folks about practicing safely.
