Not a Topo
Read full descriptionHide full description
Not a Topo is an application that complements paper topos for rock climbing. It does everything that the guidebooks can't do, without replacing them. Not a Topo allows on thousands of climbing routes everywhere in France to: - Instantly locate at the foot of which route you are on thanks to a patented technology of image recognition, a bit like Shazam for music. - Keep a log of your climbs easily and directly on the application. - To find your way on the approach steps thanks to your GPS location. - To know where to buy the official topos of the sites where you climb Not a Topo is not a guidebook and should not be used as a replacement for them but as a complement. Not a Topo is part of a sustainable development approach to rock climbing and is involved in user education. We are committed to donating 70% of the profits of the application to the associations in charge of the equipment and maintenance of natural climbing sites. Since May 2022 we already gave back more than $450 to climbing associations !
