SafeAir Walk: Find Your Clean-Air Window to Step Outside Today

Description and use

SafeAir Walk offers a privacy‑first, zero‑cost solution that turns complex air quality data into actionable, personalized outdoor guidance.

Problem

People ignore air pollution and heat because data is buried in dense charts, leading to unsafe outdoor activities.

Outcome

SafeAir Walk delivers a privacy‑first, zero‑cost solution that turns complex air quality data into actionable, personalized outdoor guidance, enabling users to safely enjoy the outdoors.

Workflow

• 1. User searches city or uses GPS
• 2. App fetches AQI and apparent temperature from Open‑Meteo APIs
• 3. Each hour is evaluated against deterministic thresholds for the chosen health profile
• 4. The algorithm selects the optimal 30‑60 minute window and alerts if conditions deteriorate
• 5. If Ollama is available, a local LLM streams a warm, plain‑language explanation; otherwise a template is shown

Evidence

SafeAir Walk tells you the single best 1-hour window to step outside today — based on real air quality forecasts and heat — tailored to your health profile.
