WeatherMaster review
A free Android weather app with provider choice, widgets and forecast alerts.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
WeatherMaster is a free, open-source weather app for Android from PranshulGG. It suits people who want to choose a weather data provider rather than rely on a single source, and who value configurable widgets and updates. The project publishes its source under the GPL-3.0 license. It focuses on general weather rather than a narrowly defined forecasting use case.
Provider choice is a central part of the app: the supported list includes Open-Meteo, Met Norway, NWS, SMHI, DWD, Meteo-France, FMI, ECCC, BMKG, AccuWeather, WeatherApi.com, Gismeteo, Met Office, AEMET and IMD. Some providers require users to supply their own API key, so selecting one may involve extra setup. Air-quality information is available from supported providers. The breadth of sources makes WeatherMaster a fit for users who want to compare provider options, while those seeking a single-source experience may prefer a simpler app.
The app combines daily and hourly forecasts with background updates, weather notifications and widgets in multiple sizes and layouts. Notification update behavior is configurable; weather animations and theme settings offer further customization. Community and email are listed as support channels. The supplied feature list does not include radar or severe-weather alerts, so buyers who need those capabilities should look elsewhere. For Android users who value open source, provider choice and configurable presentation, WeatherMaster covers the essentials; it is less suited to people who need confirmed radar or severe-alert tools.
