Tiah

For farmers & outdoor workers: Tiah turns radar, NWS alerts & storm climatology into one calm Safety Score for where you are now, with on-device AI that explains why.

Tiah is a calm, source-cited severe-weather companion for the people who can't just head indoors when the sky turns. Farmers and ranchers, construction and utility crews, outdoor guides, first responders, and anyone who lives, works, or travels through storm country.

Pull it up before a long drive, an outdoor shift, or a backyard cookout, and Tiah tells you in plain English what the weather is actually doing where you are. Not a wall of icons. A clear, honest answer.

WHAT TIAH SHOWS YOU

• One Safety Score for your exact location, built from live weather, air quality, storm reports, lightning, wildfires, earthquakes, and active NWS or Environment Canada alerts. • A live radar, satellite, and infrared map with smooth time animation, tornado warning polygons, storm-cell motion, predicted tornado halos, and local storm reports as they arrive. • An Alert Center that brings warnings from the National Weather Service, Storm Prediction Center, NASA FIRMS wildfires, USGS earthquakes and floods, and EPA air-quality monitors into one place. • A Wildlife tab for hikers and birders, with eBird and iNaturalist sightings near you. • An on-device AI assistant that reads your local conditions and explains the threats in normal language. Apple intelligence works out of the box on supported iPhones, with no key required. You can add your own OpenAI, Anthropic, or Google key if you prefer a cloud model.

BUILT FOR PEOPLE WHO WORK OUTSIDE

If you make your living in the weather, Tiah was built with you in mind. Farmers planning the day's fieldwork, crews on a job site, and anyone on an outdoor shift can turn on a Worker profile. Tiah then filters alerts and shows published OSHA, ACGIH, ANSI, and USCG thresholds for heat stress, wind, lightning, and air quality right next to the live forecast. It is there to inform your own judgment, never to give you orders.

PRIVACY-FIRST

• No analytics SDKs, no advertising trackers, no third-party identifiers. • Your location stays on your device. • Sign in with Apple is the only identity option, and Guest mode works too. • AI chat goes only to the provider you choose. Nothing is logged on a Tiah server, because there is no Tiah server.

IMPORTANT

Tiah is an informational weather-awareness tool, not an emergency warning system. It is not a substitute for official NWS, Environment Canada, USCG, or local emergency broadcasts. In a life-threatening situation, always call 911 or your local emergency number.

Weather forecasts carry real uncertainty and conditions can change quickly. Any decision about whether to work, drive, evacuate, or take a safety action is always yours.
