Canairy: Air Quality Alerts

Canairy watches the air for the places you care about (your home, your kid's school, the cabin, the trail) and only pings you when it actually matters.

Canairy pulls real readings from:
• PurpleAir's neighborhood sensor network (the same data wildfire watchers use)
• EPA AirNow's official regulatory monitors
• Google's pollen forecast: grass, tree, weed, plus the top species near you

You set the threshold for each location. Canairy keeps an eye on the air around the clock and texts or pushes you the moment it crosses your line. When the air clears, you get a one-line "we're back to good" message, no anxious thumbing through the app to find out.

WHAT MAKES IT DIFFERENT
• Multiple locations: track every place that matters, not just one
• Real sensor data side-by-side, with attribution. No black-box "air quality score."
• Pollen forecast for allergy sufferers, free on every plan
• Quiet hours that hold across push and SMS: pick the window once and Canairy stays out of it
• Worsening, clearing, and trend alerts, each with the right message for the moment
• Available in English and Spanish: screens, help, texts and notifications

PLANS
• Free: 1 location, push notifications, in-app history, ad-supported
• Plus: 5 locations, hourly updates, SMS alerts, daily forecast text, no ads
• Pro: 10 locations, 30-minute updates, priority SMS, no ads

Canairy was built by parents of two, for the moments that matter: a kid with asthma, a grandparent who shouldn't go for a walk today, a wildfire 40 miles upwind. We try to earn your trust the boring way: by being right, being quiet, and always showing our sources.

Permissions
• Location (optional): only used to suggest nearby sensors when you add a place
• Notifications: the whole point. Free on every plan.
• Internet: to fetch readings
