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. WHAT YOU GET - Current conditions, a 10-day forecast and the full 10-day hourly outlook - Precipitation nowcast, and severe weather alerts from official agencies - Weather Changes, so you hear when the forecast shifts - Comfort Index from 0 to 100, with activity ratings, clothing guidance and practical tips - Lifestyle indexes for stargazing, laundry, frost and exercise - Air quality index with a pollutant breakdown, plus pollen levels - Tropical storm tracking with the official NOAA forecast cone - Dew point, cloud cover, wind gust, snowfall and a 24-hour pressure graph - Day and night detail, golden-hour quality for sunrise and sunset - Moon phase, moonrise and moonset, illumination and lunar zodiac - Historical comparisons and monthly climate averages, drawn from decades of records - Notifications for rain on the way, weather changes, a daily summary and the full moon - Custom alert thresholds you set yourself - Search by place name, coordinates or Plus Code - Trip Weather Planner, with a forecast for every stop - Unlimited saved locations, and iCloud sync across your devices 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.
