CelsiusFahrenheit

Finally understand the temperature scale you didn't grow up with.

Celsius & Fahrenheit Widget shows your current local temperature in both units simultaneously — on your Home Screen and Lock Screen. No tapping, no converting, no math. Just glance and learn.

The widget background pulls a live photo of your city from Unsplash, 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

- 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. Your current city is detected automatically.

Easily convert between Celsius and Fahrenheit in the app.

HOW IT WORKS

Temperature data comes from Open-Meteo, a free and accurate weather service. City background photos are sourced from Unsplash with full photographer attribution. Location is used only to fetch local weather — nothing is stored or shared.

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."
