TopoKit is free for a limited time. Get it before January 1st, 2027 and the whole app is yours forever. 1.2 adds custom offline basemaps, improved routing, and more.
TopoKit is a mapping app for people who actually work with maps.
Not a desktop GIS squeezed onto a phone, and not a hiking app pretending to handle real data. TopoKit sits in between: it reads the formats you already use, treats coordinate systems properly, and gets a field map set up in minutes. Made by a working GIS technician for geologists, ecologists, foresters, surveyors, archaeologists, cavers, and anyone whose work starts where cell service ends.
BRING YOUR OWN DATA
Import GeoTIFF, GeoPDF, GeoPackage, GeoJSON, GPX, KML, and KMZ. Connect any XYZ or WMS tile server by URL. Export your points, lines, polygons, and tracks as GPX, KML, GeoJSON, or GeoPackage with elevation and timestamps intact, ready for QGIS, ArcGIS, or Google Earth.
RASTERS THAT LAND WHERE THEY BELONG
Drop in a GeoTIFF or GeoPDF and it lines up on the map. Automatic CRS detection across 4,000+ coordinate systems, on-the-fly reprojection, and no manual georeferencing. Stack as many map sheets as you need in a single project.
BUILD YOUR OWN OFFLINE BASEMAP
New in 1.2. Pick an area anywhere on Earth and TopoKit builds a topographic basemap right on your device: hillshade, contours at the interval you choose, slope shading, lakes, rivers, coastline, roads, trails, parks, and boundaries. Built from open Copernicus elevation and Overture Maps data in minutes. Once it's built, it works fully offline for good.
A WORKSPACE, NOT A LIST OF PINS
Everything lives in a project: features, imported maps, tracks, and photos. Organize layers in a tree with folders, drag-and-drop reordering, and visibility and opacity per layer, just like your desktop GIS. A project is one folder you own. Copy it, back it up, or hand it to a colleague.
DRAW AND MEASURE WITH ONE SET OF TOOLS
Drop points, draw lines, polygons, and circles. Distance, area, radius, and bearing update live as you draw, with tappable unit switching. Just need a number? Read it and close the tool. Attach photos to any feature, save style presets for pins, lines, and polygons, and set custom icons per folder.
OPEN ON YOUR MAC. WALK OUT THE DOOR.
Build the map on your Mac, and pick it up on your iPhone, already synced through your own iCloud. Working across two devices is safe: TopoKit notices when another device changed the project, merges the edits, and keeps a backup you can restore from the project menu. Pin a project and it's always on the device.
TAKE IT WHERE THERE'S NO SIGNAL
Download tiles from any tile server you've added, elevation data, and basemaps once per device and take all of that and all of your data offline. Record GPS tracks on your iPhone with four accuracy profiles, auto-pause, and live distance, speed and elevation stats. Search still finds your layers, the names on your basemaps, and typed coordinates.
PLAN A ROUTE
Search for a place or tap the map to add stops, and create a route for walking, cycling or driving. View and work with the elevation profile with a full range of stats, then save or share the route in all the listed file formats, or send it to Apple Maps or Google Maps.
BUILT FOR PRIVACY
No account. No sign-in. No analytics. No tracking. Your projects live on your devices and sync only through your iCloud. TopoKit only goes online for Apple's base map, search, and directions, the App Store, the elevation and map data you ask for, and map servers you add. It also checks topokit.ca for where the map data lives.
PAY ONCE OR MONTHLY
From January 1st, 2027, new users choose a one-time purchase that unlocks the app forever or a simple monthly plan. Your work is never held hostage: if a plan ends, TopoKit stays a free viewer and you can export every project, any time.
Built and supported by one GIS technician in British Columbia.

TopoKit is now free to download. Get it before 1 January 2027 and it's yours forever. If you already bought TopoKit, you own this update and every one after it, on every iPhone and Mac signed into your Apple Account. Nothing to buy or restore.
BUILD YOUR OWN OFFLINE BASEMAPS
Pick an area and TopoKit builds a topo map of it right on your iPhone or Mac, with shaded relief, contours, slope angle, trails, roads, water and place names. Start with the Light or Dark look from the new Basemaps button, or set your own colours. Once it's built, it works with no signal.
TAP OR SEARCH THE MAP
Tap a trail, a peak or one of your own lines and a card tells you what it is. Save trails and parks from your basemaps into your project. Search finds their names even with no signal. Hold your finger on any spot, or right-click it on a Mac, to see its height, slope, sunrise and sunset.
ELEVATION PROFILES FOR EVERY LINE
Open the profile from any line's card, including recorded tracks and trails on your basemaps. Select part of the chart to see the climb for that stretch, and it lights up on the map.
ADD ROUTE
Directions is now Add Route. Add stops by searching or tapping the map, and the roads between them fill in for driving, walking or cycling. Check the elevation profile before you save, then share the route as a file or open it in another maps app.
ADD AND REMOVE POINTS
While you draw a line or an area, or edit a saved one, drag the small dot between any two points to add a new point there. To remove one, tap it twice and choose Delete, or right-click it on a Mac.
NEW PINS, AND WHICH WAY YOU'RE FACING
Points have a new pin that looks the same on iPhone and Mac, with its name underneath. Add a point from a peak on your basemap and it keeps the peak's name and height. On iPhone, your location dot is orange now, with a little nose that shows which way you're facing.
REBUILT SETTINGS AND SAFER SYNC
Settings works like the settings in your other apps, and the Mac has a proper Settings window. Sync merges changes from your other devices instead of overwriting them, and you can restore any backup. You can also copy, paste and duplicate layers and folders, even between projects.
FIXES ACROSS THE BOARD
Lots of fixes on both iPhone and Mac. Imported maps line up more accurately, imports and exports keep more of your data, and it's much harder to lose your work.
And on iPhone, something is hiding at the bottom of Settings. Keep pulling.
