DualWeather (°C+°F)

DualWeather shows every temperature in Celsius and Fahrenheit at the same time. Your unit comes first, following your device's language and region settings, and the other sits right beside it, on every screen and in every widget. One tap on the temperature puts the other unit first. There is no conversion to do in your head.

READY FOR THE IPHONE DUO Closed, the controls sit in the right-edge column under your thumb. Open it like a book and read Celsius on one page and Fahrenheit on the other, or set it to two columns. Stand it half open on a table and the forecast sits up top with the controls below.

FREE, AND STAYING FREE There are no subscriptions, no in-app purchases and no ads. Every feature below is part of the app for everyone. Nothing is held back, nothing expires, and nothing about you is sold to pay for it.

WEATHER IN A VOICE YOU CHOOSE Five voices narrate your forecast: Neutral, Best Friend, Mean, Comedian and Occultist. Where your device supports on-device generative AI and it is enabled, DualWeather writes the commentary locally. Otherwise, the same voices draw on writing prepared in advance. Your forecast and location are never sent to an AI service.

PRIVATE BY DEFAULT There is no DualWeather account to create. There are no ads, and the developer does not sell your data or share it with advertisers. Your device sends the coordinates needed for weather directly to the providers, with no DualWeather server in between. DualWeather stores weather data and saved places on your device, and can sync saved places through your personal iCloud account. DualWeather never stores your location on a server it controls. If you prefer not to use your device’s location, switch to manual mode, pick a city, and leave location services off. The city you pick then stands in for your location everywhere: your forecast, severe weather alerts, precipitation notifications, custom thresholds, widgets, complications and background refresh all run for it.

EVERY SCREEN YOU OWN One app covers iPhone, iPad, Mac, Apple Watch, Apple TV and Apple Vision Pro. Same design, same icons, same forecast, built natively for each one. Home Screen and Lock Screen widgets, watch complications, Live Activities, the CarPlay dashboard widget, the Mac menu bar readout, the Apple TV Top Shelf and the visionOS immersive environment are all included.

WHERE THE WEATHER COMES FROM Forecasts, air quality, pollen and historical records come from Open-Meteo. Severe weather warnings are quoted word for word from the national services: the National Weather Service in the United States, Environment and Climate Change Canada, and MeteoAlarm across Europe. Tropical storm data comes from the NOAA National Hurricane Center. Outside those alert regions DualWeather shows no severe weather warnings, so please keep your own national service to hand.
