What Zenith is & how it differs
Most launchers give you a grid of icons spread across pages you swipe between. Zenith throws out the grid. Understanding that one change makes everything else about it make sense.
One open surface, not a grid of pages
Your home screen in Zenith is the sky — a single, open surface that fills the whole screen. There are no pages to swipe through and no fixed grid of slots. Everything you see is drawn onto this one surface, and it's the only home screen there is: press Home from anywhere and you land back on the sky.
What looks like empty space isn't wasted. It's the surface your apps rise onto when you reach for them.
Your apps are stars you reach for
In Zenith, an app, folder, or shortcut you've placed is a star. You don't hunt for a star in a grid — you hold the empty sky and a ring, a wheel of your apps, blooms right under your finger. Slide onto the star you want and lift to open it. Your apps live one gesture away instead of spread across screens.
Stars gather into groups, and the sky can hold as many as you like without ever feeling crowded, because nothing is on screen until you call for it.
Why it's built this way
A grid makes you go to your apps. Zenith brings them to you, wherever your finger already is. That's the whole idea: less reaching, less swiping, a calmer home screen that stays out of the way until you want it.
Zenith runs on Android 8 and newer. It's safe to try — making it your home screen is a setting you turn on and off, so nothing here is permanent.
