Set Up a Minimal Launcher on Any Car Screen

Phone launchers are built for thumbs at 30 cm — widgets, folders, news feeds. A car screen is a different animal: glanced at, tapped with less precision (sometimes through gloves), often at night. KM Launcher is a home screen built for exactly that surface — and it's free, no root required.

What makes it car-friendly

• Fully transparent window — on a projected display the wallpaper shows through untouched, so the mirrored scene stays clean.
• Fixed low-distraction dark theme — it doesn't flip to white at noon or blind you at night; it just stays dark, deliberately.
• An editable grid that fits your screen — column count slides from 2–8 in portrait and 4–12 in landscape, stored separately per orientation, re-flowing live as you adjust.
• Drag to rearrange, slots stay put — icons shift out of the way as you drag; removing an app can leave an empty slot so your muscle memory survives.
• Sensible defaults — first launch auto-fills every launchable app sorted by name; newly installed apps surface at the top.

Setting it up

1. Install KM Launcher (any Android 8.0+ device).
2. Press Home and choose it as your default launcher when Android asks.
3. Long-press anywhere to enter edit mode — adjust columns with the side drawer, drag tiles into place, clear slots you don't need.

Where it fits

• With KoalaMirror — as the home screen of your projected desktop, which is the pairing it was designed around.
• Aftermarket Android head units — replace a cluttered vendor launcher with something calm.
• Tablets and wall-mounted panels — anywhere a glanceable grid beats a busy phone launcher.
