Most weather apps give you numbers. Thermo Diem gives you context.
A 72° day after a week of freezing cold feels completely different than 72° after a scorching heat wave. That’s because human comfort is relative — your physiology adapts to what you experienced yesterday.
Thermo Diem compares current apparent temperature directly to yesterday, tomorrow, and future days of the week, answering the only question that matters when stepping outside: "How does today feel compared to yesterday?"
THE SCIENCE OF APPARENT TEMPERATURE
Ambient air temperature only tells half the story. Thermo Diem implements advanced biometeorological models (NOAA Wind Chill, Rothfusz Heat Index, and Steadman’s psychrometric heat balance) — calculating the thermodynamic balance between human skin and the surrounding atmosphere:
• Vapor Pressure & Humidity: Accounts for evaporative cooling resistance.
• Wind Velocity: Measures forced convective heat loss from exposed skin.
• Direct Solar Radiation: Incorporates direct thermal gains from daylight and UV index.
The result is true Apparent Temperature, evaluated directly against your recent baseline.
