The smart weather app built for your plants.

Standard weather apps check the air high up, often missing the ground-level frost that kills your plants first. The My Cozy Plant app monitors the real microclimate where your garden grows. Get clear alerts for surprise freezes, summer heatwaves, and high winds tailored to 225+ plant varieties.

Smart Watering Advisor

Using Evapotranspiration (ET0) metrics, this app calculates exactly when your soil is losing moisture. Know when to deep-water and when to wait, preventing both wilt and root rot.

🔬

Botanical Physics

Our algorithm factors in plant-specific physics: roots in pots freeze faster than those in the ground. We adjust alerts if your plants are in pots, shielded, or in a greenhouse.

Why weather apps usually fail gardeners

Standard forecasts measure air at 6ft high. On clear, calm nights, the temperature at ground level can be 3°C to 5°C (5°F - 9°F) colder. This app bridges that gap by calculating soil-level risk, ensuring you never wake up to a surprise frost again.

Expert App Support & FAQ

Does the app support my Zip or Postal Code?

Yes. The My Cozy Plant app works with Zip codes in the USA, and Postal codes in the UK and Canada. We use high-resolution local weather data to provide accuracy for your exact microclimate.

Can I switch between Celsius and Fahrenheit?

Absolutely. The app automatically detects your region to set the standard unit, but you can manually toggle between °C and °F (as well as mph and km/h) at any time in the Settings tab.

Does the app work without a signal?

Yes. The app features a synchronized data repository that caches the latest 48-hour forecast locally. You can check your garden's status even when your allotment or backyard has no signal.
