Finally understand the temperature scale you didn't grow up with. CelsiusFahrenheit shows your local temperature in both units at once — on your Home Screen and Lock Screen. No tapping, no converting, no math. Just glance and learn. 5-DAY FORECAST IN BOTH UNITS See the next five days with every high and low in Celsius and Fahrenheit together. In the app, each day gets a range bar so you can see at a glance how warm the week is running. On your Home Screen, the forecast widget lines up all five days, and you choose which unit leads. Widget backgrounds show a photo of your city from Unsplash that changes daily, so it feels native to wherever you are. Whether you're an American trying to make sense of a 22°C forecast or a visitor staring down 87°F, the answer is always one widget away. WIDGETS INCLUDED - Small Home Screen widget — primary unit large, secondary unit below - Medium Home Screen widget — both units side by side at full size - 5-Day Forecast widget (medium) — daily highs and lows in both units, plus the current temperature - Lock Screen circular widget — both readings stacked in the corner - Lock Screen rectangular widget — location name + both readings Choose Celsius-primary or Fahrenheit-primary depending on which unit you're learning. On the forecast widget, touch and hold, tap Edit Widget, and pick the unit that leads — or leave it on Automatic to follow your device. Your current city is detected automatically. IN THE APP - Current temperature in both units over a photo of your city - 5-day forecast with highs, lows and conditions in both units - Convert any temperature between Celsius and Fahrenheit, with fun facts along the way - Always fresh: opening the app or tapping a widget fetches the latest data, and you can pull down to refresh any time HOW IT WORKS Temperature and forecast data come from Open-Meteo, a free and accurate weather service. City background photos are sourced from Unsplash with full photographer attribution. Your location is used only to request local weather and a photo of your city — the app never stores it, and there are no accounts, ads or tracking. Can be used as a widget on visionOS! A mnemonic to get you started: "Thirty is hot, twenty is nice, ten is cool, zero is ice."
