Weather tools
Weather forecast, lightning distance, wind chill, heat index, and tides.
Weather Forecast
Uses barometric pressure trends to predict weather changes. The app tracks pressure over time and indicates if conditions are improving or deteriorating. Note: this is based on local sensor data, not internet forecasts.
Lightning Distance
Estimates how far away lightning is. Tap when you see lightning, then tap when you hear thunder. The app calculates the distance using the speed of sound.
Wind Chill
Calculates the 'feels like' temperature based on actual temperature and wind speed. Shows risk levels for frostbite.
Heat Index
Calculates the 'feels like' temperature based on temperature and humidity. Shows danger levels for heat-related illness.
Tide Estimator
Estimates tide times based on the last known high tide, using the average 12h 25m tidal cycle. Useful for coastal activities.
