Bar colour is gradient — rolling through to pitches you’ll stand up for.
Why it exists
Nothing on iOS was built for riding dirt.
So planning a ride means a route builder that treats gravel as a wrong turn, exporting it to something else to actually follow it, and rolling out anyway with no real idea how much of the day is dirt or where the fuel runs out.
TerraADV does the lot in one app. Plan it, see what you're in for, and ride it — surface, climb and fuel range worked out before you turn a wheel.
The map
Every red line is a road you can’t ride today.
This is the country between Mansfield, Eildon and Warburton, as the app draws it right now. Every one of those red lines is an official closure, pulled from the state feed, over terrain shading that shows you the lie of the land before you get there. None of it needed a single rider to report anything.
Planning a ride
Three profiles, not a dirt toggle.
Pick how rough you want it. The routing engine reads what the road actually is — sealed, gravel, or a track — instead of treating dirt as a detour to be avoided.
ADV
Mixed sealed and gravel
The default. Forest roads, station tracks, dirt highways — the stuff a loaded adventure bike handles at pace.
Hard ADV
Aggressive unsealed
Bring a mate. Routes here assume you're happy to pick the bike up more than once.
Same two towns. The sealed way is 93 km. The dirt way is 235. That’s not a detour setting — it’s a different day out. Either way it flags the closed roads before you commit.
Scenic when you want it
Direct, scenic, or max scenic. It routes you past peaks, lookouts, passes and waterfalls rather than guessing at a vague "prettier roads" slider.
It knows how far your tank goes
Tell it your bike once. It works out where the fuel gap is on every route after that — and warns you before you commit to one you can't finish.
Compare before you commit
Two or three options side by side. Colour the line by surface or by steepness, save it, or send it out as a GPX.
Loops
Sometimes you just want to ride.
No destination in mind? Set a distance, pick a direction, and it builds a loop that ends back where you started. Take the one it gives you, or roll the dice again.
Ascent and descent come out equal, because you finish where you began — and you still get the surface mix, the steepest pitch, and whether you’ll make it round on the fuel in your tank.
Out on the ride
Turn-by-turn that keeps working when the bars drop out.
Download your state before you leave and the whole lot comes with it — map, terrain, elevation, and the routing itself. That last part is the one that matters: most apps can show you a downloaded map but can't work out a new route without signal.
So when you miss a turn 60 km from the nearest tower, it just reroutes. Voice guidance, a speed readout, hazard warnings ahead, battery saver for the long days, and it records the ride so you've got the GPX afterwards.
Coverage is already national — every Australian state is downloadable today.
What the map already knows
Official closures, on the map from day one.
TerraADV pulls the state road-closure feeds every day and draws them straight on the map. Seasonal closures, fire and flood damage, roads shut for the winter.
This bit needs nothing from anyone. It's there the moment you install the app, and closed roads are routed around by default.

And what riders add
The things only another rider would know.
A gate that's been locked since March. The causeway that's washed out. Forty kilometres of corrugations that'll shake your panniers loose. Riders mark these as they find them, and everyone behind them gets the warning.
You get it whether you report or not
Warnings show up on your map and call out ahead of you on the ride. They’re there for everyone, from your first day with the app.
Reporting happens when you've already stopped
At the gate you can't get through, or the crossing you're sizing up. That's when you've got the phone out anyway — not at 80 km/h.
Backing someone up is one tap
Most of what keeps the map honest isn't new reports. It's other riders confirming what's already there.
No signal, no problem
Reports queue on your phone and go up when you're back in range. You never have to think about it.
Why you can trust it
One person shouldn't be able to close a road.
So they can't.
-
Someone else has to back it up
A report shows on the map straight away, but it won't send anyone the long way round until another rider has been past and confirmed it.
-
You can't confirm your own
Your vote doesn't count on your own report. If you want the routing to respect your closure, someone has to ride it and agree with you.
-
Old news expires by itself
Conditions change. A washout from six months ago drops off on its own, so you're not routed around a puddle that dried up in autumn.
Your data
Your rides aren't the product.
TerraADV doesn't track where you ride. Navigation runs on the phone, so there's no live feed of your position going anywhere and no trail of where you've been being collected in the background. Nothing about your riding is sold, shared or handed to advertisers.
You don’t need an account to ride
Plan, navigate and download maps without signing up for anything. Your position is worked out on the device as you go, so no live feed of where you are goes anywhere.
What signing in adds
An account gets your routes and garage on both the phone and the web planner, and lets you join in the rider reports. That's the only reason anything leaves the device, and it's stored here in Australia.
Private unless you publish it
A saved route is yours. Other riders only see it if you deliberately publish it to the community.
No ads, ever
The subscription is the business model. There's no advertising in the app and no reason for me to know anything about you beyond making it work.
The beta
What you're actually signing up for.
No mystery and no fine print — here's how it works.
It arrives through TestFlight
Apple's system for testing apps. I send you an invite, you install from there instead of the App Store. Two minutes, and it keeps itself updated after that.
It's free now, and free later
Nothing to pay while we're testing. When it does go on sale, everyone who rode with it during the beta keeps it for nothing.
New builds land every week or two
You'll watch it change under you. Now and then something that worked last week won't — that's rather the point, and it's when I most want to hear from you.
Keep your own copy of anything precious
Every route exports as a GPX. Beta data can get reset while I'm changing things underneath, and I'd much rather you had a copy than found out the hard way.
Where the app's up to right now
I'd rather tell you now than have you find out on the tracks.
-
Solid
Route planning across all three profiles, offline maps for every state, turn-by-turn with voice, Route DNA, rider reports and official closures.
-
Newer — where I need your eyes
Rerouting when you go off-route, how accurate the ETAs are on mixed surfaces, battery drain on a long day, and whether marking a stretch of road picks the right bit of it.
-
Not there yet
CarPlay. Android. And a fuller community section — track ratings, and browsing what other riders have published. Some of it works on web today; the rest is where this is going.
Who it's for
If you'd rather take the dirt road, you're who I built this for.
Doesn't matter whether that's High Country tracks on a big adventure bike or your first few gravel roads on something smaller. If you like not quite knowing what's around the next bend, I reckon you'll get something out of this.
All you need is an iPhone, a mount, and a way to charge — navigation apps are hard on batteries, and honest numbers on mine would help me a lot.
Coverage is already national, so wherever you ride works. The map just comes good fastest where a few riders overlap — so tell me where you ride, and if your patch is filling up, you'll hear from me sooner.
What helps me most
Tell me how it goes.
Especially the times it gets something wrong — a road it shouldn't have sent you down, a surface call that was off, an ETA that was nonsense. That's the stuff I can't find on my own, and every bit of it makes the next version better.
Mark a gate or a washout if you're stopped there anyway. Honestly though, one good note about a bad route is worth more to me than fifty pins.
No forms, no surveys, no weekly check-ins. Just one email address, straight to me.
About the price
A$50
/ year, when it ships
Roughly a tank and a half. It pays for map hosting and the official closure feeds, and keeps me building it.
Beta testers get it free for life. Consider it payment for the field reports.

Tell me where you ride — that's what decides which batch you land in.
Got it — you're on the list. I'll email you when there's a spot.
Something went wrong sending that. Email hello@terra-adv.com and I'll add you manually.
Who's building this
I'm Nathan. I ride around Victoria, and I built TerraADV because there had to be a better answer than planning a route in Gaia GPS and uploading it to a Garmin.
That handoff is fine if you enjoy the process and you’re tech-savvy enough to move files between devices — but it’s not everyone’s jam. TerraADV is built for everyday riders who just want to plan a day out and go, with the hazard map getting sharper as more of us ride and report.
It's a one-person project. When you email, you get me.
