Support
Need help or found a bug? Email support@spurmaps.app. Include your macOS version and, if it's about a specific file, attach the file: the fastest fixes come from a file we can open.
Files
Which files does Spur open?
GPX 1.1 (tracks, routes, and waypoints, including Garmin's heart rate, cadence, power, and temperature extensions), FIT activities and courses from Garmin, Wahoo, Coros, Suunto, Polar, and other devices, and TCX files. Open a file by double-clicking it, dragging it onto the Spur icon, or with File ▸ Open. Several documents can be open side by side.
My file has no elevation data.
Spur derives a profile from terrain data automatically. Estimated values are marked with a tilde (~) in the stats. This needs a connection the first time; the result is kept with the file so it works offline afterwards.
Can I convert FIT or TCX to GPX?
Yes. File ▸ Export as GPX… writes the open document as a standard GPX 1.1 file. Spur never modifies your original file.
Maps
The map says Offline.
Spur switches to its built-in world map when there is no connection or the online map fails to load. Everything still works; the online map returns automatically when you're back online. Map styles are unavailable while offline because the built-in map has one light and one dark skin, chosen by the style you had selected.
How do I change the map style?
Use the Map Style button in the toolbar or View ▸ Map Style. Automatic follows your Mac's appearance (Topo in light, Night in dark); Satellite shows Esri imagery.
How do I color the route by heart rate or power?
Use the Color By button in the toolbar. Only metrics present in the file are offered.
Quick Look
Finder doesn't show map thumbnails or previews.
macOS picks the app that provides Quick Look for a file type. Make sure Spur is in your Applications folder and has been opened at least once. If another app still wins, select a GPX file in Finder, press ⌘I, choose Spur under Open with, and click Change All. Thumbnails may take a moment to refresh.
Units and stats
How do I switch between kilometers and miles?
View ▸ Units offers Metric, Imperial, or Automatic, which follows your Mac's region (UK regions get miles with meters for elevation). The choice applies everywhere at once, including Quick Look.
What do the segment stats mean?
Drag across the chart to select a range. The stats strip then shows distance, time, climb, and average grade for just that range, and the map highlights it. Press Esc or click the ✕ to clear it.
Sharing and printing
How do I share an image?
Click Share in the toolbar. The image is exactly what the window shows: the map as framed, the title, the stats, and the profile when the chart is visible. Use File ▸ Export Image… to frame it yourself, pick an aspect, and save it as PNG, JPEG, HEIC, or PDF at the size you need.
How do I print a map?
File ▸ Print… prints a paper map on the light style. In the Spur section of the print panel, choose Fit to one page or a true map scale such as 1:50,000; long routes tile across pages with overlap, distance markers, a scale bar, and the elevation profile with each page's portion highlighted.
Accessibility
Spur supports VoiceOver throughout, including an audio graph of the chart, and honors Reduce Motion and Reduce Transparency. If something is hard to use with assistive technology, please tell us.
