Read full description

E Launcher puts your car's controls and live status on your iPhone. Lock the doors, start cooling the cabin before you walk out, check your tyres before a long drive, or find where you parked. All from one screen. IMPORTANT: REQUIRES E LAUNCHER APP ON YOUR VEHICLE This is a companion app. It connects only to vehicles running the separately installed E Launcher head-unit software. Without that, there is nothing for this app to connect to. WHAT IT DOES NOT DO E Launcher cannot start or stop the engine, switch the vehicle on or off, or move the car. YOUR CAR HAS TO BE ON AND REACHABLE Controls and live readings work only while the car's head unit is awake and the app can reach it: - On Wi-Fi, your phone and the car must be on the same network - On Bluetooth, your phone must be near the car - From anywhere else, the car needs its own internet connection If the car is asleep or offline, the app shows the last information it received, and commands will not go through until it is reachable again. CONTROL*: - Lock and unlock the doors - Climate: temperature, fan speed, A/C, auto mode, airflow direction, recirculation, front and rear defrost - Windows: open, vent and close, or set each window on its own - Ambient lighting modes - Suspension height, where fitted - Power side steps, folding mirrors, rear display and daytime running lights *Note: Available features depend on your vehicle. Some vehicles support the full set of controls. On others the app can show live status only, and cannot send commands. LIVE STATUS: - Battery charge and fuel level, with remaining range - Odometer, split into fuel and electric distance - Cabin, outside and coolant temperatures - Pressure and temperature for every tyre - Doors, windows and lights at a glance on a top-down view - Service interval and vehicle health LOCATION AND NAVIGATION: - See where your car is parked on a map - Send a destination from your phone straight to the car's navigation DASHCAM: - Browse and play clips recorded by the launcher's dashcam - Live view from the car's cameras Requires a vehicle with dashcam support, and a Wi-Fi connection to the car. THREE WAYS TO CONNECT: - Wi-Fi: full speed when your phone is on the same network as the car - Bluetooth: works near the car with no network at all - Cloud: check on your car and control it from anywhere, as long as the car is online PRIVACY: - No account, no sign-up, no ads - No tracking and no analytics — nothing about you is collected or sent to us - Your paired cars and settings stay on your iPhone - Your phone pairs directly with your car, and the connection is encrypted - Every new phone must be approved on the car's own screen before it can connect LANGUAGES: English, Arabic, Spanish and Russian. Never operate vehicle controls while driving, use them only when it is safe to do so. E Launcher is an independent app and is not affiliated with, endorsed by, or sponsored by any vehicle manufacturer.
