WristTopo: offline topo maps and turn-by-turn navigation for Apple Watch

It puts a detailed offline topographic map on your wrist, with full turn-by-turn navigation, so the phone can stay in your pack.

The problem with Apple Watch outdoors

You are an hour past the trailhead. There is no signal, the next junction is unsigned, and the map you need is on your wrist instead of buried in your pack. That is the situation WristTopo is built for.

The Apple Watch is now a capable piece of outdoor hardware: accurate GPS, a bright always-on screen, fast interaction, and, on Ultra models, strong battery life. The harder part is navigation. The watch can record a run, ride, or hike perfectly well. The question is whether it can also serve as a map and route tool when you are away from roads, phone signal, and easy decisions.

The usual workarounds are familiar: carry the iPhone for the map, follow a bare GPX line without much terrain context, or use a third-party app that handles one part of the problem but compromises elsewhere. WristTopo is built on a narrower premise: the map itself should live on the watch and be readable at a glance.

How WristTopo works

TL;DR: Plan a route on the iPhone, sync it to the watch with offline map tiles, then leave the phone behind. The watch handles turn-by-turn navigation, the topo map, and activity recording offline.

WristTopo is built by a single developer, eighteen months in. The core loop is simple:

• Plan or import a route on the iPhone over a topographic, satellite, or 3D terrain map
• Download offline map tiles around the route or area
• Route and tiles sync to the watch automatically
• On the trail, the watch shows your position, draws the route, and delivers turn cues
• Distance to next turn, ETA, and elevation profile stay on the wrist

The map and the trail

Two things make WristTopo stand out.

The first is the content. Hiking trails are colour-coded to local conventions, mountain-bike trails are shaded by difficulty, cycle paths are marked, and field features such as huts, shelters and water sources appear on the map. Hill shading gives the terrain shape. Satellite and winter styles are available on the watch itself.

The second is rendering. WristTopo uses its own watch-focused map engine, so the map pans and zooms smoothly rather than feeling like a small companion view borrowed from the phone. On a watch, that is the difference between glancing at a dot and reading the ground around you.

On the route, the map centres on your position and can orient to the way you are facing. The watch also shows the route’s elevation profile, including the climbing ahead. On Series 9, Ultra 2, and later, Apple’s double-tap gesture lets you switch between the map and stats without touching the screen.

A worked example: in the developer’s own testing, continuous turn-by-turn navigation with activity tracking on an Apple Watch Ultra 3 draws roughly 7-8 per cent of battery per hour. That is more than twelve hours on one charge. Smaller and older models draw more, so take that as a best-case reference.

Planning, recording, and on-watch routing

Routes start on the iPhone over a topographic base with satellite and 3D terrain layers. Routing profiles include hiking, cycling, mountain biking, and as-the-crow-flies navigation, and they can be combined in a single route.

GPX import is central. WristTopo can import GPX files as-is and auto-detect turns from the track shape. With Snap to Trails, it can map-match the GPX to the real trail and road network, so turn cues land at actual junctions and can include trail or street names. The original and snapped versions are shown side by side before you accept the change.

Recording is independent of navigation. Start a workout once at the trailhead, then switch routes, check another line, follow a bail-out option, or navigate somewhere new without interrupting the activity file. WristTopo records 34 activity metrics and supports custom screen layouts, so the watch can show the data fields that matter for the day.

You can also record in Apple’s Workout app or another third-party recorder, while using WristTopo just for maps and navigation. That matters if you already have a preferred training platform.

Backtrack can retrace your exact path to the start, offline. WristTopo can also show several routes on the watch at once, making it easier to compare a planned route with a shortcut, extension, or escape option.

On-watch routing can generate a route to a chosen point without the phone, though it needs a data connection. For remote days, plan ahead and download.

Compatibility

• Apple Watch: Series 4 and later, including Ultra models. Double-tap requires Series 9, Ultra 2 or later.
• iPhone companion required for planning, GPX import, and offline tile downloads.
• Map content includes topographic, satellite and winter styles, hill shading, hiking and MTB trails, cycle paths, huts, shelters and water sources.
• Routing covers hiking, cycling, mountain biking, as-the-crow-flies, and mixed profiles within a route. GPX import includes an optional Snap to Trails feature.
• Activity sync: Apple Health. Strava sync is on the near-term roadmap.

Things to note

WristTopo is deliberately focused. It is a maps-and-navigation app, not a full training platform or a social route-discovery network.

The privacy model is simple and transparent: no ads, no tracking, no account requirement, and no business built around profiling where users go. There is a free version to try, with Pro available as a subscription or a one-time purchase.

Summary

For Apple Watch users who spend real time outdoors, WristTopo closes a specific gap: a high-quality offline topographic map, route planning, GPX handling, turn-by-turn guidance, Backtrack, and activity recording centred around the watch. It complements the kit covered in our hiking technology guide.

It will not replace every route-planning, training, or analysis tool. Its job is more focused: make the Apple Watch useful as a serious wrist-based navigation device, while letting the phone stay packed away.

FAQ

Does WristTopo work fully offline?

Yes. With the route synced and map tiles downloaded, navigation runs on the watch with no phone or data connection: map, route line, turn cues, Backtrack, and activity recording. Creating a fresh route directly from the watch is the main exception.

How long does the Apple Watch battery last with WristTopo running?

In the developer’s testing, continuous turn-by-turn navigation with activity tracking draws roughly 7-8 per cent per hour on an Apple Watch Ultra 3, comfortably more than 12 hours on one charge. Smaller and older models draw more.

Can I record my activity in another app while using WristTopo for navigation?

Yes. Apple’s Workout app, or another third-party recorder, can run alongside WristTopo for navigation. WristTopo’s own recording also syncs to Apple Health.
