Whether you're studying, writing, coding, reading, or simply reflecting, Focus Window helps you enter a deeper state of concentration with ease.

Moon Clock is a customizable clock that shows the Moon as it appears now from a location you choose, including its phase, illumination, and viewing angle. As time passes, light and shadow shift across its surface, making the Moon feel close enough to hold. Moon Clock builds a three-dimensional Moon from lunar surface imagery and elevation data. Dynamic lighting reveals the terrain, down to the shadows cast by craters and ridges. Choose from fonts, text effects, layouts, and Moon styles to make the clock your own. The core clock experience, real lunar phases, and multiple layouts are free. A one-time purchase of Moon Clock Pro permanently unlocks: • Every font, text effect, and Moon style • The ability to create and save your own text styles • The ability to create and save freeform layouts No account or sign-in is required. Location access is optional, and you can choose an observing location manually instead.
