Wyndo

Wyndo is a weather decision engine, not just a forecast app. Instead of hourly graphs, it reads the conditions and answers with a direct go now, wait, or avoid verdict with reasoning behind every call—for runs, rides, dog walks, and race days.

The decision engine uses a veto-then-grade model combining multi-source weather data. Hazards like extreme heat, storms, dangerous pavement temperature, and poor air quality can veto an outing outright. Only what remains is graded for comfort, ensuring favorable comfort conditions can never cancel a safety veto.

Wyndo offers features including Ask for natural-language questions, Paw Check for pavement heat and dog paws, a run planner, a heat-adjusted pace calculator, and race-day weather pages for major marathons. For dog walks, it checks pavement heat and can warn based on a dog's size, coat, age, and health.
