Ombak: ride the wave of your own roads
A Malaysian-owned navigation app built on open infrastructure and honest data — live traffic with peer presence, guidance that adapts to you, on-device motion intelligence, true private mode, and a delivery fleet mode built in. 66 builds shipped.
ombak · /ˈom.bak/ · waveThe sovereign stack that already ships.
While others pitch what a Malaysian nav app could be, Ombak is one that is: turn-by-turn guidance in your language, live traffic from a regional edge, a car that keeps moving when GPS hiccups, and a courier's whole run claimed with one QR scan — all on infrastructure Malaysia owns.
- Versioned offline maps with a safe in-place update
- Voice guidance follows the app language
- Multi-stop trips with on-route search across the whole road
- Toll plazas, R&R stops and fuel surfaced along your route
“Stay straight to take the E12 ramp” — 3D guidance, speed chip, live ETA with confidence.

Six things Ombak does properly
Live traffic you can trust
Real-time congestion, hazard reports and routing served from a nearby regional edge — reroute responses around 1.7 s. Other Ombak drivers appear as live dots on your map, peer-to-peer. And a road with too few samples stays honestly grey instead of wearing a fabricated colour.
Guidance that adapts to you
Voice instructions follow the app language, and you choose how chatty it is. On arrival Ombak tells you which side of the street your destination is on — left, right, or an honest “ahead” when it genuinely can’t tell. Trips finish themselves when you arrive; no button ritual.
Motion intelligence on-device
A constant-velocity Kalman filter keeps the car gliding through GPS hiccups, map-matching snaps the arrow to the road you’re actually driving — elevated roads included — and wrong turns are caught sooner. During re-planning the camera keeps moving with your true position: we move the map with the truth, never the truth to fit the map.
Trips, planned the local way
Multi-stop itineraries, “find on route” across the whole road, toll plazas, rest stops and fuel surfaced along the way. Ombak won’t dive into shoplot back-alleys to shave seconds — and when traffic truly changes, it offers a switchable alternative (~2.5 min quicker) it never force-swaps.
Private mode, truly private
Flip it on and nothing is remembered locally — not searches, trips, driving-style stats, route habits, not even saved places. Session-only by design. Live traffic and hazard sharing keep working on purpose: your private drive still helps everyone else see the road.
A delivery fleet, built in
More than a nav app: courier drivers scan a QR to claim a run, get drops sequenced by the engine on a live run board, and record proof at the door — signature, cash-on-delivery in Ringgit, optional photo and OTP — read back from the same production backend the dispatcher watches.
Honest by design
The product principle underneath every build: say exactly what you know, ask exactly what you must, and keep exactly what you were promised.
Every claim carries a confidence
ETAs are labelled live, typical or unknown — mirroring the fusion honesty gate. Degraded paths say so plainly with a retry prompt instead of an opaque error or a silent blank.
It asks you, sparingly
Hazard checks are scenario-aware: quiet when a slowdown is just your announced turn or a red light, progressively longer between asks, capped at three per trip.
Your phone stays yours
Private mode suppresses every on-device record a drive can leave behind. Verification is yours to give — a “cleared” verdict fades a report instead of misleading everyone downstream.
No fake features
Capability flags decide what you see — lane guidance, traffic-light countdown and transit stay switched off until their data is real, instead of shipping a demo-grade lie.
One gateway. Zero provider lock-in.
The app never knows which provider or country supplies the data — every client talks to one normalized contract, and provider quirks live in server-side adapters. A new country is a new adapter set and a capabilities row; the app code does not change.
