Plan on the web
Sketch multi-day, multi-track plans in the studio. Drag waypoints, snap your line to real trails, and watch surface and elevation update as you go.
Mixed-surface route planning & navigation
Roads end.
Your journey doesn’t.
Overlandi plans routes that mix motorway, gravel and singletrack, and grades every section from 1 to 10. Plan on a laptop, then ride it on your phone or on the handlebar dash pod.
The track grade
Every section of track, graded 1 to 10.
Overlandi reads the OpenStreetMap tags for each way (surface, track type, road class) and gives it a grade. Where OSM has no surface tag, a model trained on the surrounding roads fills the gap. The colour on the map, the elevation profile and the dash pod is always this grade.

- 2path / rough trackFootpaths and rough tracks

How it works
Big-screen planning,
app-based navigation.
02
Mix routing algorithms
Hand the motorway to Google, the dirt to Overlandi’s own algorithm, and everything between to BRouter — one seamless route, stitched from whichever suits each leg best.
03
Navigate from your pocket
Sync to your phone and navigate turn-by-turn — offline tiles, live progress for your group, and quick detours when the trail throws you a surprise.

Plan on the web, ride on the phone
Same route, both screens.
Build the plan in the browser, where there’s room for the map, the elevation and the grade of every section. It syncs to the iOS app, which navigates it turn by turn.
One plan, four kinds of terrain
An adventure bike weekend.
One route, planned in one place. Each leg is routed by whichever engine suits it, and the colours below are the grades you’d see in the app.

Features
Everything between A and B.
For trips where the good part is the bit Google won't route.
Plan on web, go on app
Build the route on a big screen. It syncs to the phone app.
Multi-day, multi-track
Split a long trip into days or loops inside one plan, and switch between them on the road.
Snapping & surface analysis
Routes snap to OSM ways. Each section gets a grade from 1 (alpine path) to 10 (motorway), plus gradient.
Track up
A third map orientation alongside north-up and heading-up. It turns the map to follow the track ahead and zooms to fit it, so a set of switchbacks fits on screen.
Profiles for every machine
Adventure bike, enduro, gravel bike or 4×4. Set how much dirt you want and the router weights for it.
Calendar-aware planning
Pin waypoints to dates and times (campsite bookings, ferries, seasonal closures) and plan each day around them.
Intelligent GPX export
Exported route points go on junctions and turns, not at fixed spacing, so a hairpin stays a hairpin on the GPS.
Garmin sync
Connect a plugged-in Garmin in the web planner to push routes and waypoints to it, and pull recorded tracks back into a plan.
Diversions & detours
Branch off to a campsite and rejoin by the quickest way, or route round a closure. The rest of the day is untouched.
Groups & collaboration
Share a link and edit the same plan together. Everyone's phone gets the latest version.
Live group locations
Group members show on the map while you ride. Out of signal, their last known position stays, with a timestamp.
Help button
One tap alerts your group with your location. It's free.
Signal at the campsite
Mobile coverage for each overnight stop in the UK and France, so you know before you get there.
Wild camping finder
Candidate wild-camp spots along the route. Local camping rules are yours to check.
Offline routes & tiles
Routes and maps are stored on the phone, so navigation carries on with no signal.
OSM quests
Short questions along the route, like confirming a surface or checking a spring. Answers go back to OpenStreetMap.
POIs along the route
Fuel, water, food and viewpoints near your line, not within a 50 km circle of it.

Phone stays in your pocket.
A 1.43-inch round AMOLED that mounts on the bars and takes directions from the Overlandi app over Bluetooth. The phone can stay locked in a jacket or tank bag, which saves its battery and keeps it out of the rain.
We’re running it on a Suzuki DR-Z at the moment. These are screenshots from the display itself, not mock-ups.
850 m to a right turn. The bar fills as you get closer. 
At the junction the bar is full and turns green. 
Further on. The grey arc is the part already ridden.
- The junction
- The real shape of the junction, drawn from the map: white is the way you come in, green is the way you leave. A dog-leg looks like a dog-leg.
- Distance and bar
- Distance to the turn in big white digits, and a segmented bar that counts down the stretch to it, so you can read it at a glance at speed.
- The outer ring
- The whole day’s route, coloured section by section with thetrack grades from the app. The gap at the bottom is the start and finish; ridden track goes grey, and a white tick marks where you are.
Snapping & surface analysis
Know every surface before you travel it.
Overlandi snaps your line to real OSM ways and grades every metre from1 (difficult) to 10 (motorway) — a grade of 0 just means it hasn’t been graded yet — and you can help grade it. See the surface mix, the steep ramps, and exactly where the tarmac runs out — while the route is still a draft, not a roadside discovery.
- Per-metre 1–10 road-type grading on every track
- Steepness analysis from real terrain data — know the ramps before they know you
- Surface mix and elevation profile for each day
- Tune the grade you want per vehicle profile
Navigation · Track up
Never guess what’s round the bend.
North-up pins the map to the compass; direction-up spins it to your heading — and both can push part of the bend clean off the edge of the screen. Track up orients to the trail itself and fits as much of the way ahead as the viewport will hold, so the whole switchback is on screen before you reach it. Never be left guessing what’s on the other side of the switchback again.
- Orients to your track and fits the most of the trail ahead on screen
- See the whole bend coming — no leg left off the edge
- Still one tap from north-up or direction-up
Diversions & detours
Bend the route, don’t break it.
Real trips never follow the plan exactly — a campsite worth the hop, a pass that didn’t survive the winter. Overlandi bends the route around the moment and keeps the rest of your day intact.
Diversion — worth the hop
Branch off the main track to a campsite or any POI near your line. When you’re done, Overlandi rejoins the track ahead by the quickest route — no backtracking.
Detour — around the surprise
Rockfall on the pass? Reroute around just the blocked stretch. Everything after it — the trails, the camp, the plan — stays exactly as you drew it.
Itinerary & export
Fixed dates. Faithful exports.
The unglamorous details that make or break a trip — a campsite booked for Friday, a GPX your old sat-nav can’t misread — handled properly.
Plan to the calendar
Pin waypoints to dates and times — the booked refuge, the hour a col road opens — and shape each day around the points that won’t move.
GPX export that doesn’t cut corners
Most tools drop route points at set intervals and can miss vital detail like switchbacks. Overlandi intelligently plots the route, placing points where it actually changes — every hairpin, turn and junction — so nothing gets lost on the way to your device.
Wild camping · coverage · POIs
End the day somewhere good.
The night matters as much as the miles. Overlandi finds wild-camp pitches and campsites along your line and, in the UK and France, checks the cell coverage at each one — so you know before you commit to the col.
- Wild-camp pitches and campsites found along your route — whether you may camp there is yours to check
- Cell coverage at any point in the UK and France, from real tower data
- Fuel, water, food and viewpoints found along the route
Real-time sharing & collaboration
Plan it together, in real time.
Send a link and your group is in the same plan — live cursors, instant edits, no “final_v3_FINAL.gpx” email chains. And when the plan is ready, the group travels it together too.
- Share links with view or edit access
- Live presence — see who’s moving what, as they move it
- Everyone syncs the latest plan to their own phone
Groups · live locations · help signal
Your whole group, on one map.
Invite your group and everyone gets the plan — and each other. Live locations on every phone while you travel; if someone drops out of coverage, their last-known position stays on the map, time-stamped. And when it really matters, one tap on Help tells the whole group where you are.
- Invite anyone to a group — they get the route and the live map
- No signal? Last-known location shown, with how long ago
- A Help button that signals distress to the whole group, with your exact position
AI co-driver · MCP
Tell the map what you want.
The co-driver speaks fluent route. Ask for three days of gravel with a camp each night, and watch it work on the live map — it searches real places and unpaved ways, drops the waypoints, snaps every leg and grades the surface as it goes.
- Finds the good stuff: gravel and forest tracks, mountain huts, fuel and water stops — even named military roads
- Edits like a planner: waypoints, per-leg profiles and alternatives, icons, and a dated itinerary for each day
- Imports and exports GPX, follows your reference tracks, saves and loads whole plans
- Speaks MCP — connect Claude or your own agent and drive the studio from outside

Garmin sync
Straight onto your Garmin.
No cards to swap, no clumsy file shuffling, nothing to install. Plug your Garmin into your computer, connect it in the web planner (Chrome or Edge) and Overlandi syncs both ways — your planned routes and waypoints land on the unit, and the tracks you recorded out there come back into a plan, ready to analyse.
- Two-way sync — push routes & waypoints, pull recorded tracks
- Reads the unit's own manifest to put each file in the right folder
- Pulled tracks become an editable, surface-graded plan
- Validated on real handhelds like the GPSMAP 66i
Low-bandwidth by design
Built for the edge of the map.
Overlanding takes you where the bars run out. Overlandi is engineered to keep working on a trickle of signal — and to keep its bearings when GPS gets shaky.
Highly optimised tiles
Map tiles squeezed to the smallest honest size, cached on the device and fetched only for the ground you're actually heading over — not a whole region you'll never see.
Vector where it counts
Features stream as vectors wherever possible — razor-sharp at any zoom from tiny payloads, and restyled on the fly without re-downloading a thing.
Prioritised loading
Your route and the road ahead draw first; labels, terrain and the nice-to-haves fill in after. On a trickle of signal the map is useful in the order that matters.
Steady through weak GPS
When the fix drifts or drops out, Overlandi holds a smooth heading and position instead of letting the marker pinball across the map.
Low-power mode
Dial GPS accuracy down to sip battery on the long days — coarser, less frequent fixes that still keep you on the line, with full precision a tap away when you need it.
Open source
Built on open maps.
We help build them too.
Overlandi stands on the shoulders of the open-mapping community — and pulls its weight. Travelling with us makes the map better for everyone, on every app.
The community map
OpenStreetMap
Every trail, surface tag and track comes from OpenStreetMap — the open map of the world, made by people who actually travel it.
Machine learning
Trail surfaces, learned
Where the map goes quiet, our model doesn’t — trained on terrain, tree cover and gradients, it grades every track 1–10, from barely-there singletrack to main roads, even where OSM has no surface recorded.
You can help too
Help grade the map
Classify the surface from the app and it goes directly to OSM — every answer makes off-road routing more reliable, for everyone.
OSM quests
Travel with a mission.
While you ride, untagged tracks near you show a small “?” — tap one and confirm its surface in a second. Your answer sharpens Overlandi’s surface grading and, if you link an OpenStreetMap account, fixes the map for everyone, on every app.
The trail is waiting.
