Changes stay in a draft until you tap Save, and the live keyboard below the tabs shows the draft as you go.
Background
My photo, or Plain, Retro grid, Night city, Lasers, Rings, Waves, Circuit, Honeycomb, Galaxy, Aurora, Bokeh, Lightning or Hearts, drawn in your light colours. Ten base colour pairs sit below.
Effect
Brightness darkens the background and Blur softens it, so lit keys stand out against a busy photo.
Lights
Style, colour set, the One colour and Enter key colour, speed, thickness, glow and Light up letters. See
the key lights.
Keys
Rounded, Square, Pill or Bubble keys. Key opacity at 0 leaves only the glowing outline; higher fills the keys with their colour.
Font
Nine keycap fonts and eight letter colours. These change how the keys look, not the text you type.
Sparkles
Typing effects that burst from the key you press - sparks, stars, hearts, fire, comets, bubbles, snow, confetti or petals - and emoji stickers in the corner of some keys.
Sound
Click, Mechanical, Laser, Synth, Pop, Piano, Typewriter, Drum, Bell, Water drop, Glass or None, with a volume slider. The app makes these sounds itself. They stay quiet on silent or vibrate unless you turn on Play sounds on silent.
Size
Keyboard height from 70 to 130 percent, letter size from 70 to 140 percent.
