SWAP is a weather app with international appeal. This project aims to provide a human weather in real time through a geotagged community. It is a collaborative community service, accessible to all, free on App Store and Google Play. This app answers the question "What time is it currently in a particular place" to complete weather forecast. Meteorology is a predictive science that allows to know the weather in the near future. SWAP does not want to forecasting but to observe.
