Features

Legal following distance

Continuously shows your distance to the vehicle ahead and warns when it drops below the statutory minimum that applies from 60 km/h (35–100 m under Circular 38/2024/TT-BGTVT) — reducing the risk of fines under Decree 168/2024/NĐ-CP.

Collision & lane warnings

Detects cars and motorbikes closing in dangerously and warns about lane drift at speed — by voice, no need to look at the screen.

Speed-sign recognition

Reads speed-limit signs on the road and reminds you when you exceed the limit.

Smart dashcam

Auto-records 1080p with GPS while you drive, cleans up old clips, keeps safety-event moments. Replay with the full detection overlay, distances and speed exactly as shown while driving.

Uyên — voice assistant

Say “Uyên ơi” to ask about traffic law, fines, your speed or the distance to the car ahead — completely hands-free.

Public traffic cameras

806 public cameras across Ho Chi Minh City and Da Nang — browse by list or on a map, some streaming live video. Know the roads before you head out.

Frequently asked questions

Is uyên.ai a certified ADAS?

No. uyên.ai is an advisory aid running on your iPhone. All warnings and displayed distances are camera-based estimates with a margin of error. The driver remains fully responsible for observing the road and controlling the vehicle.

Does it heat up the phone or drain the battery?

On-device AI does work hard while you drive. The app throttles itself: it lowers processing rates, dims the screen when nothing needs attention and pauses recording if the phone runs hot. Plug in for long drives.

Where does my data go?

Video and detection run entirely on your iPhone — dashcam footage never leaves the device. No data sales, no ads, no cross-app tracking. Details in the Privacy Policy.

When does it reach the App Store?

We are in a free TestFlight beta, polishing the app with real drivers. The App Store release follows this phase — beta testers hear about it first.

Safety first

uyên.ai is an ADVISORY aid, not a certified ADAS. Displayed distances are camera-based estimates with a margin of error. The driver remains fully responsible for observing the road and driving safely. Never operate the phone while driving — use your voice.
