Karter - Car Headunit Launcher

Karter is a modern home launcher for Android car multimedia screens, landscape tablets, and large touch displays. Replace the factory interface with one driving-focused screen: GPS speed, weather, Bluetooth, music controls, volume, and your apps — all at a glance.

WHY KARTER?
• Landscape layout — readable on head units with large touch targets
• Driving dashboard — speed, weather, media, and connection status on one screen
• Customizable dock — quick access to maps, music, phone, and settings
• Built-in phone screen — recents, contacts, and dial pad (Bluetooth hands-free)
• Optional driving assistants — seat belt voice reminder and speed gauge heat colors
• Privacy-minded — contacts and call history stay on your device

DRIVING DASHBOARD
See everything on the home screen:
→ GPS-based speed gauge (km/h)
→ Live weather for your location (Open-Meteo)
→ Now playing track, artist, and album art — system media controls
→ Bluetooth connection status and linked device names
→ Media volume slider and shortcut buttons
→ Maps shortcut — one tap to your preferred navigation app

DOCK AND APPS
• Swap dock icons for maps, music, phone, and settings with your own apps
• Move the dock to the left or right on wide screens; optional dual dock for the passenger side
• List all installed apps in the drawer; hide the ones you do not need
• Personalize appearance with light, dark, or system theme

PHONE SCREEN
Use your phone even on head units without a SIM:
• Recent calls and searchable contacts
• Direct dialing from the dial pad
• Outgoing calls over Bluetooth to a paired phone (hands-free)
Permissions are optional — other features keep working if you skip them.

DRIVING ASSISTANTS (enable in Settings)
• Seat belt voice reminder — short spoken prompt after speed stays above a threshold
• Speed gauge heat colors — gauge tint shifts warmer as speed increases
• Internet connected alert — brief sound when connectivity returns after a drop

SETUP
1. Open Karter and complete the setup wizard.
2. Set Karter as your default home app (required).
3. Grant only the permissions you want: location (weather + speed), notification access (now playing info), nearby devices (Bluetooth), contacts / call log / phone (built-in phone screen).

WHO IS IT FOR?
• Aftermarket Android multimedia systems
• OEM in-car tablets and landscape Android head units
• Large tablets used in landscape
Note: Portrait phones are supported, but the primary design targets landscape car displays.

PRIVACY
Location coordinates are sent only to Open-Meteo for weather. Contacts and call logs never leave your device. Details: in-app Settings → Privacy & data.

REQUIREMENTS
Android 8.0 (API 26) or newer.

Keep your eyes on the road while driving. Karter is not a navigation or emergency service — it is a home screen that makes your existing maps and phone apps easier to reach.

Set Karter as your default launcher — a simple, capable home screen for the road.
