Climbing & Partners: Cactux

Send a sector to your Apple Watch and navigate with no signal. Create, suggest and record trails offline — it all syncs when you're back.

Cactux is the climbing app built in Mexico: community guidebooks, offline walking navigation to the boulder, and the partners to go climbing with.

Download a guidebook before you leave and use all of it at the crag with no signal. Walk to the block along the real approach trail, not a straight line. And if you have an Apple Watch, wear it.

AT THE CRAG

• Offline navigation — Follow the approach trail to a boulder or a route. Works with no data and no coverage. • Apple Watch — Send a sector to your wrist and move around the area without pulling out your phone. Mark points and record trails from the watch. • Topos — Photos of the wall with the lines drawn on them, plus grades, quality and description. • Sector maps — Boulders and routes colored by grade, with parking, trails and your own saved points. • Offline mode — Download the guidebook, photos and map tiles. It all lives on your phone.

GRADES THE WAY YOU READ THEM

• Convert between V-scale, Font, YDS and French. Pick your system and the whole app follows it — without touching what the first ascensionist wrote.

PARTNERS

• Find climbers — A map of climbers near you, with their grades, goals and availability. • Sessions — Propose a quick outing, rock or gym, and get it confirmed. • Trips — Plan longer ones: invitations, join requests, shared expenses, gear lists, carpooling and the forecast for the destination. • Follow climbers and see what they're sending. • Messaging — One inbox for all of it.

ALSO

• Log your ascents, rate quality and suggest a grade. • Events — Festivals, comps and meet-ups from the community. • News and videos from the climbing world. • In English and Spanish.
