Forecasts you can flip

Explore your instruments
Tap station readings to explore graphs, recent history, highs, lows, and averages. Follow temperature, humidity, wind, rain, UV, pressure, sunlight, and lightning.
Make your Watch your own
Choose individual readings or a wide three-reading complication. Combine temperature, wind, UV, rain, lightning strikes, and more. Choose mint, instrument colors, white, or watch-face styling; the face controls final color rendering.



Built around your own station
Connect securely with your personal access token, stored in device Keychain. Readings are shared with your paired Apple Watch and widgets. Explore labeled sample weather before connecting a station.
iPhone requires iOS 17 or later. Apple Watch requires watchOS 10 or later. Displays Fahrenheit, mph, and inches. Forecast availability and updates depend on the weather provider, network connection, and Apple background scheduling.

Your weather, right on your watch face
Make your watch face your own weather dashboard. MintSky offers nine single-reading instruments in circular, corner, inline, or rectangular complications on compatible faces. A wide Station Trio combines any three readings: try Temperature · Wind · UV, Temperature · Rain · Strikes, or Wind · Gusts · Rain. Customize each reading and choose MintSky mint, colors by instrument, white, or watch-face styling. Shapes and colors depend on the face. Browse sample complication previews inside the Watch app.
