About

Be I/O

Features
Read full description

Be I/O makes sense of air quality in terms that apply to you. Rather than broad categories like "moderate" or "unhealthy," Be I/O estimates how much PM2.5 you'd actually take in, right now, doing what you're planning to do. Choose an activity — a 30-minute walk, or a 75-minute hard run — and see whether to Be Inside or Outside for it, and how much of your estimated daily intake it would account for. Be I/O works out your ventilation rate from optional health details: age and weight, or your resting and maximum heart rate, or — for the fitness nerds — the litres per minute you breathe in each heart rate zone, straight from a metabolic test. Connect to your own PurpleAir or AirGradient sensors over your local network for near-real-time readings, free and without an account. No sensor of your own? Subscribe to use the public monitor nearest you. A subscription adds: * Air quality from the sensor nearest you, wherever you are * What each run, ride and walk of the last 30 days cost you, from Apple Health * A week of sensor history (for public sensors) * The Apple Watch app: current air quality, your estimated breathing rate and PM2.5 intake, each optionally shown against a baseline you choose * A PM2.5 gauge Apple Watch complication Note: Be I/O estimates are fitted to adults; the app says so when it knows you're younger.
