About this app

FrostAlert is the only mobile app designed specifically for Polish farmers and fruit growers, providing hyperlocal frost forecasts with a 4km grid resolution. Data comes from ICM Meteo models – significantly more accurate than standard weather apps.

🌡️ Ground and Air Forecast
Check the temperature at ground level (0 m) and in the air (2 m) – the ground can be up to 2-5°C colder than the air. Frost Alert shows the worst-case hourly temperature and frost probability for the next three nights (night window: 6:00 PM–9:00 AM).

🟢🟡🔴 Three Risk Levels
• Green – Safe (frost risk <20%)
• Yellow – Warning (20–49%)
• Red – Danger (≥50%)
One glance is enough to make a decision about crop protection. You can adjust the warning thresholds to suit your crops and terrain.

📍 Up to 5 locations
Add your fields and orchards to the map – using GPS or by dragging a pin. Each location has its own forecast and alerts.

🔔 Customizable push notifications
Set thresholds for 5 alert types:
• Frost probability (10–90%)
• Ground temperature (-5 to +5°C)
• Air temperature (-5 to +5°C)
• Dew point (-5 to +5°C)
React to worsening conditions before it's too late.
