Weather UP is a mobile weather app for the Philippines where your daily observations can help improve the next weather forecast.

Unlike any other weather app available, Weather UP shows you highly localized weather forecasts that extend to 5 days in advance, and updated with the latest available weather data four times a day. This is pin-point forecasting.

Weather UP acknowledges that the science of weather forecasting is not perfect! and there will be times when weather forecasts are inaccurate. This app harnesses the information from individual user's weather observations, and use this data to correct forecast errors and improve succeeding forecast accuracy.

Not only is our weather forecasts developed through years of local scientific research, this app is the first and only local crowd-sourced weather app.
