Die App gibt es doch schon mit Höhenprofil und der Möglichkeit POIs hinzuzufügen. Nur die Kommunikation innerhalb der App ist glaube ich neu.
Hier die Ankündigung, wie sie im englischsprachigen Discord steht - entscheidet selber, was tatsächlich neu ist. Ich zitiere:
After months of work, a new version of the HexaTrek app is here, designed for and with the community!
Here's what this big update has in store for you:
Real-time comments This is a long-awaited feature: you can now read and publish comments + images, directly on the map's points of interest.
Discover recent feedback from the community on: trail conditions (markings, detour, obstacles...), water availability (dry springs, active fountains...), the quality of bivouac spots, accommodation, alternative routes, grocery stores ect...
Whether you're in the middle of a traverse or planning your route, this information shared by other walkers gives you an up-to-date view of conditions on the ground.
And of course, you too can contribute by leaving a message, a photo or an alert! Together, we'll keep the trail alive and evolving.
Add your own points of interest (POIs) Have you spotted a useful or remarkable place that's not yet on the map?
Now you can add it yourself!
Simply long-press the map to open a small form: place name, type, description... After verification by the team, this new POI will be integrated into the database.
Elevation profile A practical new feature: you can now view the elevation profile between your position and a point of interest.
Refuge, pass or bivouac spot: at a glance, you know how much ascent or descent awaits you.
Updated database We have updated and enriched the application's entire database: more than 2,700 points of interest concerned, more complete and practical descriptions
Sie bitten / fordern dazu auf, die App tatsächlich mit Kommentaren und POIs inklusive Fotos zu befüllen, wobei Kommentare sogleich erscheinen, alles andere wird erst einmal gecheckt, wenn ich das auf Französisch richtig verstanden habe.
