Asthma Tracker: Peak Flow

Asthma Tracker: Peak Flow is a calm, privacy-first asthma diary for Android that helps people log symptoms, record peak flow readings and manage inhaler routines in minutes a day. Designed for practical daily use, it turns quick 10-second check-ins into useful patterns you can share with clinicians or use to spot triggers at home. The app combines symptom tracking, a personal peak flow diary with zone alerts, medication reminders and local air-quality and pollen notifications into a single clear interface, so users and caregivers can monitor trends without clutter or ads. It runs entirely on-device, respects quiet hours and produces exportable reports for appointments.

Key Features

⭐ Simple symptom logging for wheeze, cough, chest tightness, night waking and fatigue so daily check-ins are fast.

⭐ Personalized peak flow diary with a large slider entry and automatic green/yellow/red zones based on your personal best.

⭐ Comprehensive inhaler and medication tracker covering preventer, controller, rescue, biologics, oral meds and spacer use plus a rescue inhaler counter.

⭐ Smart reminders scheduled for the times you actually take your meds, quiet hours respected, and a built-in editable 3-zone action plan to share.

⭐ Real-time air quality, PM2.5 and pollen alerts with trends overlay so you can compare environment data to symptoms.

⭐ Insights and exports: peak-flow charts, severity heat-maps, trigger breakdowns, adherence stats and one-tap PDF or CSV reports for clinicians.

Advantages

✅ Fast daily use — check-ins typically take about ten seconds, helping build consistent habits.

✅ Privacy-first design stores data on-device with no account required, no ads, no analytics and no third-party trackers.

✅ Rich clinical detail in a compact interface — charts, heat-maps and exportable reports make it easy to discuss trends with a respiratory specialist.

✅ Built-in air quality and pollen notifications give practical warnings before you step outside on high-risk days.

✅ Includes guided breathing exercises and inhaler technique refreshers to support self-management between visits.

Disadvantages

❎ Asthma Tracker: Peak Flow is not a medical device and does not replace your prescriber's advice or a written asthma action plan.

❎ Peak flow zone calibration relies on a personal best value, so accurate zones require an established baseline reading.
