HUD Speedometer Guide
Transform your iPhone into a professional heads-up display speedometer. Project your speed safely onto your windshield for better driving awareness.
What is HUD (Heads-Up Display)?
HUD technology projects important information directly onto your windshield, allowing you to keep your eyes on the road while monitoring your speed. Originally developed for aircraft, HUD systems are now available in premium vehicles and through smartphone apps.

How to Set Up HUD Mode

Enable Location Services
Grant location permission when prompted. This is required for GPS speed tracking to work.
Activate HUD Mode
Tap the "HUD" button to switch to heads-up display mode. The screen will flip horizontally for reflection.
Position Your iPhone
Place your iPhone on the dashboard with the screen facing the windshield. The reflected image will appear on the glass in front of you.
Adjust Brightness & Settings
Fine-tune the brightness and color settings for optimal visibility. Darker colors work better during night driving.

HUD Speedometer FAQ
Is HUD mode legal while driving?
HUD speedometers are generally legal as they help keep eyes on the road. However, ensure the display doesn't obstruct your view or violate local laws about device placement.
Does HUD work during daytime?
HUD reflection is most visible during dusk, night, or overcast conditions. In bright sunlight, the reflection may be too faint to see clearly on the windshield.
Will HUD drain my battery faster?
HUD mode uses more battery due to continuous GPS tracking and higher screen brightness required for windshield projection. Consider using a car charger for longer trips.
Can I use other apps while the speedometer is active?
Yes! Use Picture in Picture mode to keep the speedometer visible in a floating overlay while using navigation or music apps. Note: HUD mode requires the app to be in the foreground, but PiP mode allows multitasking.
