Finally, a simple weather clock that is clean and straightforward. No ads, no accounts, no setup. Same promise kept since 2018. Launch it and you have the time, the date, and what the weather is doing right now. Set the device down on a nightstand, a desk or a kitchen counter and leave it there — the screen won't lock while the app is open. THE TIME, AS BIG AS YOU WANT IT Pinch out and the time fills the entire screen, edge to edge, so you can read it from across the room or from the doorway. Pinch in to bring it back to its usual size. In landscape the digits run on a single line; in portrait the hours stack over the minutes. SIX COLOR THEMES Black & White, Ocean, Cyan, Lime, Coral and Fuchsia — each with a light side and a dark side. Swipe two fingers left or right to move through them, or pick one in Settings. Double-tap anywhere to flip between light and dark. Every pairing is chosen to stay legible in a dark room, and the light themes lift as you dim the screen so they hold up at night. WEATHER FROM APPLE WEATHER The current temperature on an arc gauge that shows the day's full range at a glance, with a marker pointing the way the temperature is heading. Conditions, humidity, and severe weather alerts when there are any. Double-tap the temperature to switch between Celsius and Fahrenheit. Lose signal and your last reading stays right where it was. GESTURES THAT STAY OUT OF THE WAY Swipe two fingers up or down to set the screen brightness — two fingers rather than one, so picking the phone up or putting it down doesn't dim it by accident. A "?" in the corner opens a page that explains every gesture, and nothing here is gesture-only: everything can be done from Settings too. Works on iPhone and iPad. Available in English and Hebrew.
