iZen
Read full descriptionHide full description
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.

AdaptaFit builds a workout plan around your real life — your equipment, schedule, and goals — and adapts as things change. Training and nutrition finally talk to each other: the lifting you log becomes energy in today's calorie target, and your maintenance is measured from your scale, not a formula. TRAIN YOUR WAY, CHANGE ANYTHING - Get a personalized plan from your goals, experience, and equipment — home, gym, or traveling. - 374 exercises with demo videos — big-gym machines, kettlebells, bands, and a full no-equipment library. - Add or remove an exercise, build a superset, change a set type, or swap a move — today or the whole plan — without leaving your workout. - Plans hold a fixed weekly schedule, build to a deload, then ease off — warm-ups and a "+5 lb" nudge included. - Tell the planner your rules — "machines only for legs," "no supersets" — it holds them every week. BRING YOUR WHOLE HISTORY - Import from Strong, Hevy, Stronglifts, and MyFitnessPal — every set, rep, and weigh-in. Preview first; undo in one tap. - A month of imported food + weigh-ins measures your actual maintenance from day one. - Getting out is free too: export everything as CSV and JSON, anytime — even after you cancel. KNOW YOUR ENERGY - A Home graph shows the fat-vs-muscle tradeoff at your intake — a sweet-spot band for your goal, and where today is headed. - Workout calories are computed from what you actually did: sets, load, effort, and heart rate. - Apple Health steps and Active Energy fill movement rings, charts, and an energy-balance page; steps feed your calorie targets. TELL YOUR COACH WHAT CHANGED - Ask anything — from any tab or mid-workout — and it answers with your real numbers; every suggestion is a one-tap Apply card you approve. - Edits hold: say "every workout" and a superset or swap applies across your plan and stays applied. - Paste what you actually did and it rewrites the day and logs every set — "yesterday" or "last Tuesday" work. - Tell it what you did and it logs it — a meal, a treadmill walk, your weight, water, sunlight, or a supplement. CALORIE & MACRO TRACKING, DONE RIGHT - Log food in seconds with search, barcode, a nutrition-label photo, or a lookup that checks real published labels — not guesses. - Snap up to 3 photos or describe a meal — it breaks into editable ingredients saved as one re-loggable meal. - Pin protein, carbs, and fat and your calorie target updates live — or set a multi-phase plan that switches targets on schedule. BODY & WELLNESS - One-tap water, sunlight, and supplement logging with reminders. - Track body-fat %, BMI, and per-workout burn, keep private progress photos, and weigh in at a time you choose. SEE AND SHARE YOUR PROGRESS - Turn a session into a shareable card over your photo, or a sticker for your Stories. - Pinch-to-zoom charts: intake, weekly volume, weight vs a goal line, and estimated 1-rep max per exercise. ON YOUR WRIST - An Apple Watch app, a complication, and a Live Activity put your workout and rest timer on your wrist — log sets and change exercises from your watch. PRIVATE AND RELIABLE - Your diary and history stay on your device — an unexpected restart or leaving mid-workout won't lose your sets or PRs. - Back up to your iCloud with a tap in Settings, and restore on a new phone or after a reinstall with "Recover my data." Start with a free month — full access to everything. After that, one simple AdaptaFit membership keeps your adaptive plans, your coach, photo and meal logging, and daily plan generation. Available monthly or annually; cancel anytime in your App Store settings. AdaptaFit Pro is an auto-renewing subscription. Payment is charged to your Apple ID and renews automatically unless canceled at least 24 hours before the period ends. Manage or cancel anytime in your App Store settings.
