How Malaysians travel isn’t published anywhere

notuju is a free navigation app for Malaysian roads. Every drive measures the roads anonymously. notuju puts that together with public open data, like bus times, weather and the map, and gives it all back, free.

Why drive with notuju

Directions made for Malaysian roads: the exit number, the lane, the toll lane and the landmark. Some of it gets better with every drive.

The exit number and your lanes, from 1.5 km out

The next exit shows in a plate like the sign’s, with its route number and the places it leads to. notuju marks the lanes for your turn and says it: “Get into the left 2 lanes”. In the last seconds, the countdown turns amber, then green.

Missed it? The way back is ready

notuju has already worked out the way back and what it would cost: “If you miss it: +10 min”. Nothing is added to your drive unless you miss it. Next time, notuju warns you earlier at that junction.

Your drive addsWhere the junction is, the way you were heading and the hour, with nothing about you or your trip. Junctions many drivers miss become open data.

Directions the way people give them

“Keep left, after the Petronas.” notuju names what you see just before the turn: a petrol station, a mosque, a McD, a flyover or the second traffic light. Every word and voice prompt is in English and Bahasa Melayu, in a male or a female voice.

Which toll lane takes your MyRFID

From 900 m before the plaza, notuju shows where the lanes for your payment are likely to be.

Your drive addsWhich side of the plaza you went through, how you paid and how long you queued. The lanes for each card get surer, and toll queues become open data.

  • MyRFID
  • SmartTAG
  • TnG
  • Bank card

Tolls, R&R and AWAS cameras ahead

The next toll, R&R or AWAS camera shows with how far it is, and each one is a dot on the trip line. Stops come up when due: a break after two hours, your brand’s last station before a long gap.

Your drive addsWhich R&R you stopped at, when you got there and for how many minutes. How long drivers stop at each R&R, and when it is busiest, becomes open data.

One best route, with the toll in ringgit

Tell notuju once when a toll road is worth it, such as when it saves 10 minutes or more. It picks one best route by that rule. The card shows the toll for your vehicle class and says why.

Your drive addsHow long each main road took, and when. notuju builds the usual traffic on each main road from its own drivers, never from a paid feed.

Also on every drive

  • The next turn, big enough to read from the phone holder
  • The whole trip on one line, with every toll, camera and R&R on it
  • Guidance carries on through tunnels once the route is loaded
  • Buttons big enough for gloves on a motorcycle

How your drive becomes open data

The more people drive with notuju, the better both get: the directions and the data.

  1. You drivenotuju gives you directions, free.
  2. The road is measuredRoad times, toll queues and the kind of place a trip ends at. No name, no phone ID.
  3. Joined with public open dataBuses and trains, ridership, weather, visitor arrivals and the open map, from data.gov.my and OpenStreetMap.
  4. Given back, freeOne ZIP of spreadsheets for anyone, and an API for apps.
  5. Better directionsTraffic from real drives, surer toll lanes and fares checked against real trips.

See all the live numbers

notuju never keeps who you are or where you went

No sign-up, no email, no phone number. Two kinds of help are on when you start, and you can turn either off in Settings.

Help the traffic map

While you drive: how long the main roads take, how long you wait at each toll plaza, which side you go through and how you pay, where you fill up, how long you stop at R&Rs, junctions you miss, where you brake hard, where you turn back, and where mobile data drops. Never residential roads, nothing within 500 m of where a trip starts or ends or of home and work, and no name or phone ID.

Help the open data

When a trip ends at a place, or you pick a place from a search: only what kind of place it is, like Healthcare or Shopping malls, with the state, city and week. Never the place, the words you typed, the route or the time, and never at home or work.

Totals are published only for weeks that are over, from 50 per kind of place and area, rounded to the nearest 10. None of them points to one driver.

Kept on your phone

  • Home, work and the places you go every week
  • Your usual fuel brand, and when a toll road is worth it to you
  • Junctions you have missed, and your own ways around
  • How long the roads took on your own drives
  • In Settings, you can see, forget or export each one, or delete it all at once

Also sent, to do the job

  • The start and end of a route, to work out the way
  • Your positions, sent every 2 minutes while you drive, without their times, to name the roads you are on. Nothing is kept
  • One anonymous check-in a day, and one count when a trip ends, for the live numbers. Nothing about where
  • Place searches, and the area’s name when you set home or work from where you are, with your position rounded to about 1 km, never the exact spot
  • Map tiles and weather, from open-data services
  • Reports you choose to send

Questions

Is notuju free?

Yes. The app and the data are free, with no account and no ads. Apps that call the API all day can pay RM 10 for 30 days of higher limits, which pays for the server.

Do you sell my data?

No. notuju never keeps who you are or the places you went, so there is nothing about you to sell. What drivers send becomes totals, free for everyone in the ZIP. Apps that pay RM 10 for the API pay for server time, not for the data.

Why does a navigation app collect data?

Because how Malaysians travel isn’t published anywhere. Public open data shows where the roads and buses are. Only drives show how long the roads take, how long the toll queues are and what kinds of places trips end at. notuju measures that while it gives you directions, and gives the totals back.

Why isn’t it in the App Store or Google Play?

notuju is a web app: you install it from your browser. It then opens from your home screen like any other app and updates itself.

Does it work on iPhone?

Yes. Open notuju.nexstrive.tech in Safari, tap Share, then Add to Home Screen. On Android, Chrome offers Install app.

Does it work when signal drops?

Yes, once a route is loaded. Guidance and voice carry on through tunnels and dead spots. Finding a new route needs signal.

Does it run in the background, or on Android Auto or CarPlay?

No. Keep notuju open on your phone while you drive. It keeps the screen on.

Can I use it on a motorcycle?

Yes. The buttons are big enough for gloves, and the voice says each turn.

Which places does it cover?

All of Malaysia: the Peninsula, Sabah and Sarawak. Search, stops, cameras, tolls and R&R are for Malaysia only.

Where does the map come from?

From OpenStreetMap, the map anyone can edit. Exit numbers, cameras, R&R and landmarks come from it too, so you can fix a wrong or missing one there. Search also finds shops and businesses listed by Overture Maps and Foursquare.
