HUDWAY | GPS navigation apps with HUD mode for everyday commute
 
Speedometer
An app that knows speed limitations for particular road segments and alerts on them in a driving-friendly way
Features
Helps avoid speeding tickets
Knows current speed limitation — both within cities and on highways. Alerts on speed limits, as well as on speed cameras and radars.
Doesn't require much attention
Designed to be comfortably used without direct focus on it.
Your peripheral sight will be enough to keep you aware.

Perfectly works in the background
Tracks your speed and gives sound alerts when you're exceeding, even when you're using some other app (for example, some navigation one).
Works offline
Doesn't need Internet connection to work. Needs Internet only at first launch.
Use it in regular or HUD mode
HUD mode allows using your smartphone or tablet as a projector. Just place your device close to the windshield, and the screen image will get reflected and displayed on the windshield. Keep your eyes on the road — everything you need is displayed right in front of you!
