What trail app is everyone using?

Gaia

OnX Backcountry

Wikiloc ftw

AllTrails is all I’ve ever known so I kinda stick to what I know.

Depends on your location. Altrails is ok for me (Sweden)

I use Komoot, pretty decent for short hikes.

CalTopo has capabilities lacking in other maps like DEM shading.

Oh wow DEM shading seems like just what I was looking for.

Paper maps
