Apps in any size
Pull the corner of an app and it becomes 2×1, 1×2 or a big 2×2 tile. The icons around it move while you drag.
Liquid. Fast. Yours.
A whole new system on top of Android: home screen, lock screen, Control Center and App Library made of one material, Liquid Glass. No root, no flashing. Install it and set it as your home.

Lock screen
A tall glass clock that lets the wallpaper shine through, and the subject of the photo in front of it. Six clock faces, each one sized, coloured and placed in the lock screen editor. Long press the lock screen to start.

Liquid Glass
Every surface bends what is behind it at its edges and lights its rim. Drag the glass. In CometOS you tune transparency, blur, depth, refraction, edge light and colour split, and the whole system follows.
Home screen
Pull the corner of an app and it becomes 2×1, 1×2 or a big 2×2 tile. The icons around it move while you drag.
Over 500 Comet icons, each one drawn three times. Switch the whole home with one tap.
Swipe past the last page and your apps are already sorted into categories, with search on top.
Weather, clock, calendar and more, in the same glass as the dock. Folders open in place while the home zooms towards them.

Control Center
Swipe down from the right edge. Wi-Fi, Bluetooth, brightness, volume, music and every toggle you use, in glass that takes the colour of your wallpaper. Long press to rearrange it and add controls.
Made to be yours
Folders open in place with the glass growing out of them, and close back into the icon.
Clock face, size, colour, glass and widgets, edited live on your own wallpaper.
Tap Search on the home: apps, contacts, settings and the web in one place.
Music, timers and calls float over every app in a pill that grows when something happens.
An assistant built into the home. Ask, search and act without opening another app.
Open source apps, reviewed by the team, installed and updated from inside CometOS.
Pop, Dive, Rebound or Lift: choose how the home lands after you unlock.
A gallery made for the glass, or your own photos with the depth effect.
Sign in with Discord: your tags from the server, your profile and the beta channel.
CometOS finds a new version, checks its fingerprint and installs it. Nothing to download by hand.
Engine
The dock, the widgets, the notifications and the menus are drawn by the same glass engine. A slider in Settings changes all of them at once, while your finger is still on it.
object CometTuning {
// "Strength": 0.35 .. 1 .. 1.65
val strengthK = 0.35f + 1.3f * strength
// how far the edge bends the wallpaper
val amountK = refraction * strengthK
// the light on the rim
val rimK = edgeLight * (0.6f + 0.8f * strength)
}
CometOS measures your phone and picks the glass it can draw smoothly. Performance mode trades the live blur for a frosted picture made once, so pages slide without a dropped frame.
