I'm searching open source solutions…
I'm searching open source solutions to replace Strava, Komoot, and Garmin Connect like apps. 
So far, I found this app on Zapstore, looks promising: 
But it needs OSM Dashboard for OpenTracks to be installed and as well Gadgetbridge to connect with a Garmin device, both not on zapstore? 
Anyway, what are your favorite open source apps and solutions to replace outdoor and fitness apps?
