Climbing & Partners: Cactux

Bouldering, topos & guidebooks

Free · Designed for iPad. Not verified for macOS.

Track consistency, projects and private climbing sessions. Plan around the sun on iPhone and Apple Watch, and take your guidebooks offline. Cactux is the climbing app built in Mexico: community guidebooks, offline walking navigation to the boulder, and the partners to go climbing with. Track consistency in your logbook and check the sun's path to plan your day at the crag. YOUR CLIMBING DAY • Home — Plans, events, tickets, recent ascents, saved climbs and today's news in one place. • Profile and Compas — Your identity and climbing logbook, with a separate editor for partner photos, availability and visibility. 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. • Area 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, with photos, replies, reactions, stickers and voice notes. Tag your partners with @. ALSO • Logbook — Record sends and attempts, offline too. Explore your calendar, projects, achievements and reports by discipline. • Private sessions — Log duration and effort in a diary saved only on this device, with no sync between devices. • Sun — Check sunrise, sunset and the sun's position on iPhone and Apple Watch. On iPhone, explore other dates and estimated sun exposure for a wall. • Community — Photos, videos and notes from climbers who've been there, per climb, sector or whole guidebook. • Events — Festivals, comps and meet-ups from the community. • News and videos from the climbing world. • In English and Spanish. Develop routes or write guidebooks? Create and edit climbs, photos and topos from your phone, organize areas and import climbs from a spreadsheet. Publish your guidebook and share it with the community. Cactux started in Guadalcázar and keeps growing: El Salto, Cañón de San Lorenzo, Sierra del Sarnoso and more. Missing your area? Get in touch.
