THE TOOLKIT

Small details.
Whole new feel.

Create a clock from separate layers, or begin with a community design. Keep each piece editable as you tune its layout, motion and everyday details.

01 / CREATE

Build a clock from layers.

Start from a blank canvas or adapt a saved clock. Place each text layer, shape, image, widget or group independently, then refine its size, position and appearance.

  • Editable text, shapes, widgets and grouped layers
  • Alignment guides, snapping and size matching
  • Image, gradient and frosted-glass fills
  • Per-layer effects, motion and copy/paste
See the clock editor guide ↗
02 / QUICK PICK

Change clocks right from the lockscreen.

Long-press the clock to open the picker, swipe through live previews, then tap Apply. Your chosen design eases into place with a smooth transition.

  • Open the clock picker with a long press
  • Swipe through clock styles before choosing
  • Apply the selected design with a smooth transition
03 / MOVE

Let the phone set things in motion.

Give each layer its own tilt or parallax response. Add foreground cutouts for a sense of depth, then choose how the clock assembles on wake.

  • Per-layer tilt, parallax or both
  • Wallpaper cutout depth and gyro motion
  • Wake and unlock assembly styles
04 / GLANCE

Useful things, right where you need them.

Keep music, weather, device details and everyday reminders on the lockscreen as individually editable layers.

  • Music controls and visualizers
  • Live upload and download speed
  • Weather, battery and device telemetry
  • Tasks, notes and focus profiles
