OSS Weather review
A configurable, multi-provider weather app for forecasts, radar and location comparisons.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OSS Weather is a free, open-source weather app for Android and iOS, aimed at people who want to compare forecasts and choose a data provider rather than rely on a single source. It combines current conditions with hourly and daily forecasts, charts, precipitation radar, interactive maps, home-screen widgets, and side-by-side location comparisons. Air-quality and astronomy data broaden its scope beyond basic temperature and precipitation. Its mobile focus and configurable updates make it a fit for individual users who want weather information presented in several formats.
Provider choice is central to the app: supported sources include OpenWeather, Open-Meteo, AccuWeather, and Meteo France, with RainViewer also listed among integrations. Availability and API-key requirements vary by provider, so setup and access to particular data can depend on the source selected. Forecast length also varies by provider, and alerts appear only when the selected provider supports them. The app offers manual refresh or configurable updates from 15 minutes to 3 hours, along with background updates. That flexibility suits people who want to balance freshness with their own update preferences, but it does not make forecasts or alerts consistent across sources.
The feature set is broad for a free app: users can combine charts for temperature, precipitation, wind, and other metrics with radar, maps, widgets, and location comparisons. The vendor describes the app as having no ads or tracking, and says optional anonymous crash reporting can be enabled. Android requires version 7.0 (API 24) or higher; iOS is also supported. OSS Weather is a sensible pick for users who value open-source software, provider choice, and configurable updates. Those who need a fixed forecast horizon or uniform alert coverage across providers may prefer an app with those needs explicitly built around one consistent source.
