Description by Chizuru Maeda Written by the developer, not by AppBrain. Click to read.
**Sleep & respiratory trends** — With Apple Watch Series 6 or later (watchOS 9+), worn nightly with Sleep tracking enabled, see overnight respiratory trends in Smart Analysis. Pair with dinner tags to explore personal patterns.

**Works on iPhone alone** — No Watch required for daily logging, medications, peak flow, reports, and Doctor Summary.

**Apple Watch setup (recommended for full features)**
• Series 6 or later recommended for sleep respiratory trends
• Wear your watch during sleep most nights
• Enable Sleep tracking on Apple Watch
• Keep Watch paired with iPhone (syncs when near your iPhone)

**Important**
This app is for personal record-keeping and trend reference only. It does not provide medical advice, diagnosis, or treatment. Sleep respiratory values are wellness estimates, not clinical measurements. Always consult your doctor for medical decisions. Doctor Summary and reports are meant as reference material for your visits.

【 One Tap for a Lifetime of Breath. 】
"Don't live to record. Record to live."

Lazy Asthma Control makes daily asthma tracking effortless by syncing with Apple Health in the background. On good days, you don't even need to open the app—but when symptoms strike, a single tap is all it takes to instantly log your condition.

Ready to discover your true triggers? Our advanced "Analyze" feature merges your heart rate and peak flow with your environment. See exactly how your airways react when climbing peaks, skiing down mountains, or crushing an indoor gym workout.

■ ADVANCED ANALYSIS: Dedicated Environments
Go beyond basic logs. Tap the "Analyze" card to unlock specialized timelines tailored to your activities:
• Mountain Hiking: Track altitude changes, import GPX paths, and check your Safety Index.
• Winter Sports : Real-time "Cold Air Alert" tracks speed (up to 120 km/h) and temperature to calculate airway dryness risks on the slopes.
• Indoor Training : Optimized for gym workouts with a 4-second live heart rate sync and peak flow chart, completely stripping away GPS and weather noise.

■ Seamless Apple Health Integration
The app watches over your breath in the background, even when you aren’t looking.
• Auto-Sync: Retrieves heart rate, respiratory rate, and steps automatically from your Apple Watch and iPhone.
• Air Pressure vs. Vibe: Overlays local barometric pressure with your peak flow to capture weather-driven triggers before they happen.
• Lazy Recording: Skipping a day? The app automatically logs "No Symptoms" for days you don't manually enter, freeing you from the pressure of an empty calendar.

■ Key Features
• One-Tap Vibe Log: Record your current condition instantly from your phone or via Apple Watch wrist notifications.
• Retrospective Log: Forgot to log a symptom during a heavy workout? Use the intuitive slider to back-date entries up to 120 minutes ago.
• Inhaler & Medication Log: Precisely track rescue inhaler usage (puffs).
• Doctor Summary: A professional report that compresses months of data and multi-environment timelines into a 10-second overview for your doctor.

■ Why Choose This App?
• Zero Ads: No intrusive ads or slow loading times during an attack. Every second counts.
• Privacy First: Your records belong to you. Your activity is logged securely without ever storing precise location names.

■ A Note from the Developer
I live with "Silent Asthma." I created this app because I couldn't keep up with heavy, complex tools. I wanted a space that stays out of the way—where one tap is enough, and Apple Health does the rest. To remain honest and independent of ads or data brokers, we operate on a simple subscription model.

Lazy Tap, Solid Record.
Make your daily breath, your gym sessions, and your outdoor adventures smarter and freer.
