Adapte

Adapte is Free and accessible: Adapte was created in response to worsening extreme-heat scenarios and is intended to stay as accessible as possible, without ads.

Safety-first: You get clear warnings when temperature, cold, heat, or air quality move into dangerous ranges, from Adapte's own built-in hazard detection. Optional national weather alerts are also available from the US, France, India, Canada, Japan, China, and MeteoAlarm (covering Europe). Note: alerts from Japan and China are in beta.

Privacy-first: No account to create, no analytics, no advertising trackers. Your chosen settings, and optionally your local weather history, stay on your device rather than in a cloud profile.

Available in 14 languages: Chinese (Simplified and Traditional), Dari, English, French, German, Hindi, Italian, Japanese, Korean, Pashto, Portuguese, Spanish, and Ukrainian.

Weather & air quality details Adapte shows current ambient temperature, feels-like temperature, humidity, wind chill, wind speed, UV index, and storm risk with descriptive conditions like overcast clouds or clear sky. Feels-like temperatures use Australian standards that factor in temperature, humidity, wind speed, and UV exposure. For planning ahead, you can see a 16-day forecast and per-hour breakdowns.

Air quality forecasts cover up to 7 days across 27 pollutants and pollen types, grouped so you can see not only whether the air is "good" or "poor" but which specific factors are driving the risk.

Hazard warnings & guidance Adapte highlights the most serious hazard for each time period in plain language, such as extreme heat, cold, or unhealthy air quality.

Interactive maps The built-in map view lets you explore overlays for temperature, rain and snow, cloud cover, barometric pressure, and wind patterns.

Cities, locations, and alerts Search for cities worldwide or let the app use your device's location. You can save multiple cities, flip between them quickly, and choose exactly which ones send you alerts. Set your own alert hours, days of the week, and more so notifications reach you only when and how you want them.

Units, formats, and accessibility You can switch between Celsius and Fahrenheit, choose wind speed in m/s, km/h, mph, or knots, and show pollutants in µg/m³ or ppm. Date and time formats are configurable, and text sizing plus theme choices make it easier to use the app in a range of lighting conditions.

Offline Mode If the Internet is not available use offline mode to enter your own values and, if you choose, still store them in history.

Past Weather & Trends Turn on local weather history to let Adapte build a record for your cities stored entirely on your device. Adapte automatically detects unusual and long-term patterns in temperature, humidity, pressure, wind, UV, and air quality. You can also see how accurate the forecast has been for your city over time, and fill in older history on demand from a climate archive going back to 1940.
