Both units, on every temperature, all the time.
The weather app that never makes you convert.
Dual Degrees shows Fahrenheit and Celsius together on the current temperature, every hour, every day, and every feels like. Free on iPhone, Apple Watch and your home screen.


Every number, both ways.
Not just the headline temperature. Feels like, hourly, daily highs and lows, dew point: everything that has a unit is shown in both, and you choose which one comes first.
- Actual temperature
- 65°F / 18°C
- Feels like
- 68°F / 20°C
- Wind
- 5 mph / 8 km/h
- Pressure

Updated minute by minute, from the same data your iPhone's weather uses.
Widgets for every screen you own.
Fourteen widgets, six of them for the lock screen, all showing both units. A full forecast, a temperature graph, the conditions, or just the two numbers.


StormAura, free for everyone
When the weather turns, the app turns with it.
StormAura switches on by itself when severe weather is detected near you. Active alerts from the National Weather Service, the vital storm metrics, live radar, and plain guidance on what to do, all on one screen.


Live radar
Watch precipitation move across your area in real time. For Dual Degrees+ subscribers.

Lightning as it happens
Strikes appear on the radar the instant they are detected, so you can see a storm's edge.

Weather you can see
Rain, snow, fog, thunder and sun rays play on the main screen to match conditions outside.

Set it up once. It follows you.
Pick which unit leads, choose inches or millimetres, hPa or inHg, mph or knots, and pick a theme. With a free Dual Degrees Cloud account your saved cities and your settings sync to every device you sign in on.
From the App Store
Finally, a weather app that shows both. I live between the US and Canada and this saves me mental gymnastics every day.
The design is clean, the data is accurate, and the Watch integration actually works reliably. My favourite weather app.
StormAura kicked in during a thunderstorm and showed me exactly what was happening and when it would clear. Brilliant feature.
Tomorrow's weather, in both units, on your phone tonight.
