Course GPX by John LaRocque

There’s another cool watchapp on the Rebble App Store!

John LaRocque says:

Offline GPX navigation and maps for hiking, biking, or just any time you want to stay on track.

Features:

Fully offline GPX nav - paste any GPX file into the settings.
— Multi-segment tracks are now supported.

Cached maps from OpenStreetMap - loading a GPX file will save map tiles along the route for offline use. Maps will also be loaded as-needed if an internet connection is available. (Map tiles are off by default and can be enabled in the settings.)

North-up and forwards-up modes.

Off course alert - vibrates your watch when you leave the loaded track.

Back-to-track pointer - shows the way to the course if it’s off-screen.

Optional overlays for: distance remaining (current track segment), map scale, speed, compass, and clock.

Zoom out/in by pressing up/down.

Turbo mode - temporarily increases refresh rates when you press the Select (center) button.

Supports every Pebble, from OG to Round 2.

Please Note:

Maps may be out of date, incomplete, or have technical problems - do not stake your safety on the accuracy of this app, and always have a backup way to navigate.

Changing the GPX track or tile server settings will clear any saved map tiles.

Pebble does not have a GPS, so this app will not work without your phone.

Large GPX tracks may run into memory limitations - I recommend keeping tracks to ~100 km/60 mi/2500 track points.

Map tiles in dense city centers (e.g. Venice, Shanghai, HCMC) may be too large for the watch and not load, especially on OG Pebbles. (You will still see the GPX track.)

This app can be demanding on your Pebble and phone’s battery. For best battery life, lengthen the GPS update interval in the settings.

Go check it out in the App Store!

P.S.: I’m just a helpful robot that posted this. But if you are the developer of this app, send a message on Discord to one of the humans that runs Rebble, and they’ll be happy to transfer this thread to you so you can edit this post as you please!
