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.

3.3.0 4d ago
Improvements to guidebooks, navigation and events.
• Explore Areas and navigate to a climb on the same map.
• Older downloads keep access to saved climbs, photos and topos. Update the download while connected to get Area maps for offline use.
• Returning to the map no longer restarts a stopped walk or replaces a destination you chose later.
• Event organizers can adjust the framing of their cover photos.
• Improvements to event presentation and profile loading.
3.2.1 6d ago
A fuller logbook to track consistency and sends, plus a new tool to check the sun's path before heading to the crag.
NEW
• A climbing logbook with an activity calendar, projects, achievements and reports by discipline. Follow your consistency and grade progression, and log climbs that are not yet in a guidebook.
• Climbing workload: record sessions, duration, effort and attempts. This private diary is saved only on this device.
• Sun planning on iPhone and Apple Watch: check sunrise, sunset and the sun's position. On iPhone, choose another date and estimate when a wall faces the sun.
• Guide editors: capture a location on a full-screen map with GPS accuracy, capture time and nearby climbs for reference.
IMPROVED
• Pending edits show the current sync stage, photo upload progress and estimated time remaining.
• Comments with photos and videos resume interrupted uploads and automatically retry temporary connection failures.
FIXED
• Draft edits are preserved even when the original finishes syncing while you are editing.
• Ascent dates stay on the chosen day when you change time zones.
• Improvements to offline downloads, grade selection, area counts and resuming trail recording after a GPS pause.
3.2.0 Sep 30
NEW
• Redesigned profile: one view per account. If you use Compas, your partner profile includes your guides, contributions and climbing on Cactux.
• Search climbers by name from Home or the Compas map, and message anyone.
• Guide map: the «Contornos» button shows or hides area outlines and their sections.
• Editors: manage a guide's services from the app: photo, location, hours, categories and order.
• Editors: in Manage content, tap a climb to open or edit it; order and fold sections right there, and climbs renumber as you move them.
• Editors: area outlines can have holes (lake, private land, rock) that navigation routes around, shown or hidden on the map. While drawing you see trails, sections and climbs for reference, and points can be dragged.
• Editors: frame the cover with zoom and see how it will look at 16:9.
FIXED
• Content created offline is no longer sent with a temporary id.
• Visual fixes on the profile.
3.1.0 Sep 26
NEW
• Cactux is now available in all 27 countries of the European Union.
• cactux.app links to a guide or a sector that you tap inside the app, such as in a chat, open that guide or area without a trip through Safari.
• Climb rows and the map's climb card draw the climb's line on its photo.
• Open projects show in teal on topos; closed projects stay amber.
• Editors: frame an area's cover, reuse a climb's photo as a topo, and take a topo's GPS location from its photo.
• Editors: disconnected trails can be reconnected, and reordering Sections previews the new numbering even offline.
IMPROVED
• The screen stays awake while a guide downloads or a comment uploads.
• Keyboards: Done closes the keyboard in every form, and fields stay visible above it.
FIXED
• Re-walking a trail keeps the changes other editors made in the meantime.
• Retrying a comment never posts it twice.
3.0.3 Sep 24
NEW
• Climbs without a photo of their own show the topo they're drawn on, framed on their line.
• The parking pin offers both the walk along the trail and driving directions in Apple Maps, Google Maps or Waze — to the end of the road when the area marks one.
• The selected climb stands out on the map: ringed, named, and still there when you zoom out.
• Compas: people search is now a button next to your inbox.
• Manage content: swipe a row to move it to another section, edit it or delete it, and select several to file them in one go.
• Adding a climb: check its location on satellite next to the sector's other climbs, or copy another climb's location so two captures of the same block don't scatter on the map.
• Collaborators can move and reorder Areas.
FIXED
• Navigation walks the trail. Before, when a sector's only trails were approaches, the route was drawn as a straight line across the ground instead of following the path that actually reaches the climb.
• Your position draws on top of the trails instead of underneath them.
• Climb names wait until you zoom in, so they no longer cover the map.
• Offline guide editing: lists no longer stall, an Area's name and location save without a signal, and pending changes can be reopened and edited.
• Favorites, ascents and comments on a climb you created offline become available once it syncs, instead of going missing.
• An event's roster and board open correctly when you arrive from Home, a ticket or a profile.
3.0.2 Sep 21
FIXED
• Home greets you with your public profile name — the one other climbers see — and long names no longer rearrange the header.
• The photo picker no longer flickers when you add a sticker or a Compas photo.
NEW
• Find climbers by name or email from the Compas map.
• Cactux now tells you when the connection is stuck instead of loading forever.
3.0.1 Sep 16
Cactux has a new look: a redesigned interface, new brand colors and clearer controls in light and dark mode.
NEW
• Home brings together plans, events, tickets, ascents, favorites and today's news.
• Areas connects routes, boulders, photos, topos and nested areas, with complete offline downloads.
• Messaging brings conversations together, with replies, reactions, stickers and voice notes.
IMPROVED
• Profile and Compas: separate climbing logbook and partner editor, with clearer photo, availability and visibility controls.
• Maps: separate Map and Filters tabs, name search, grades by discipline and optional Section outlines.
• Topos: more room for the photo and easier access to line and marker tools.
• Guidebook authoring: organize mixed content and import climbs from spreadsheets with validation before publishing.
• Trails: one recording flow with approach, between-climbs or descent purposes and a travel mode.
• Grades and events: conversions on more screens and starting ticket prices.
FIXED
• Complete, up-to-date areas and trails when sending content to Apple Watch.
• Conversations stay open on reconnect; recordings stop when you leave and require an explicit Send.
• Removed the persistent Compas tab badge, made overlapping climbs easier to select and improved browsing between tabs.
3.0.0 Sep 15
Events now live completely on your phone: carry your ticket, answer invitations, join activities, and arrive prepared—all from Cactux.
NEW
• Tickets and activities — See tickets you bought or assigned, answer invitations, complete required forms, accept prerequisites, and register for program sessions.
• Wallet — Add compatible tickets to Wallet.
• Event board — Organizers publish announcements and pin important threads; attendees ask questions, reply, and follow conversations for updates. Posts and replies can be edited, reported, or removed, abusive accounts can be blocked, and organizers can lock a finished thread.
• At the door — Organizers scan tickets and check people in even without a signal; changes sync when the connection returns.
• Savings plans — See how much remains and when the next payment is due.
IMPROVED
• Guidebooks from your phone — Authors can now configure sector maps, connect trails, manage collaborators, replace covers, and link photos to climbs.
• Safety and control — Report specific content, block abusive accounts, and delete your account and personal data from Settings.
FIXED
• Event and climb links and notifications now open the exact content they reference.
• Trail recording no longer interprets a lost GPS signal as a real path.
2.10.0 Aug 28
Cactux 2.9.0 — multi-pitch routes from your phone, pitch by pitch.
FOR EVERYONE
• Report content — A comment, a reply, a logged ascent, a community photo or video, a guidebook photo and a whole guidebook each carry their own "Report" entry in the (...) menu. Before, you could only report the account behind it.
• Partners — Deep-water solo, ice, via ferrata and aid are now climbing types you can put on your profile and filter by. And a profile listing a type your version doesn't know yet no longer takes the card down.
• Picking a grade in the filters is a wheel now: the list no longer jumps back to your selection just before your tap lands.
• A queued post whose file is gone can now be discarded, instead of sitting at "Uploading… 0%" forever.
FOR GUIDEBOOK AUTHORS
• Multi-pitch — Write a multi-pitch route from the phone: name, grade, length, bolts, anchor type and crux per pitch, reorderable by drag.
• Each pitch draws its own line on the topo, colored from its own grade. The pitch bar tells you which one you're drawing and ticks off the ones that already have a line.
• The route's headline grade, bolt count and length come from its pitches — hardest pitch, summed totals — so you no longer enter them twice.
• And a half-drawn route explains itself when you read it: the fullscreen strip lists every pitch the route claims and dims the ones with no line yet.
2.9.0 Aug 20
Cactux 2.8.0 — search every climb, and publish your guidebook without a laptop.
FOR EVERYONE
• Search climbs — Find any route or boulder across every published guidebook from the Guides tab. Open it, or log your send right there, instead of going guidebook to sector to block.
• Topos now zoom where your fingers are, not at the center of the photo. And a pinch no longer drags the view by accident.
• A climb with no scale recorded now infers one from its own grade instead of assuming French, so a 5.10a no longer shows up as something nobody wrote.
• A queued video no longer gets lost if you close the app before it finishes uploading.
FOR GUIDEBOOK AUTHORS
The whole guidebook is now managed from your phone. No more "that part needs a computer".
• Publish, archive or delete your guidebook from the phone.
• Collaborators — Invite whoever should be editing with you, right there at the crag, and manage their permissions. Invitations open in the app.
• Zones — Put a climb or topo into a zone, or take it out of all of them. That was web-only before, so anything you created on the phone landed in "Sin agrupar" with no way to file it.
• And each zone now records its aspect, sun exposure and best seasons: questions you answer standing in the zone at two in the afternoon, not at a desk.
• Drag to reorder a sector's topos and a guidebook's trails.
• Duplicate a climb, or let AI draft its description for you.
• Remove a climb's photo without having to replace it, and fix the author and climber credits.
• Trails — Approach and climbing trails listed separately, ranked by how close they actually are to the sector.
• Delete routes, boulders, sectors, photos, trails and zones. It all queues offline and syncs when you're back.
2.8.0 Aug 18
Cactux 2.7.1 — better sharing, scrolling and commenting.
COMMUNITY
• Sharing to Instagram works — your ascent card goes over as an image, without the error that used to stop it.
• Endless media — reaching the last video loads more on its own, and once you've seen the whole sector it starts over. No more leaving full screen to keep watching.
• Notes are comments now — the same wall, called what everyone already called it.
• Two tabs instead of four: Comments puts ascents and comments in one thread, and Media stays on its own.
MESSAGES
• Your compa conversations now show under Perfil too, tagged "Compa" — tapping one takes you to the Compas tab, where you can propose a session and leave a review.
2.7.1 Aug 15
Cactux 2.7.0 — the community, on video.
COMMUNITY
• Full-screen media — the Media tab is now a grid, and tapping a photo or a video opens it full screen: it starts on its own and you swipe from one to the next.
• A scrubber to find the moment in a video, and each thumbnail now shows how long the clip runs.
• A whole guidebook's or sector's activity on one screen — ascents, notes, photos and videos, without opening block by block.
• Each climb's wall sits at the foot of its own page: yours first, everyone else's below. And you can post a photo or a note from the buttons up top, without scrolling to the end.
• Fixes: a video that sat on its poster now starts; the like, comment and save buttons no longer toggle the sound; and a text-only note stops hanging on "Uploading note…" forever.
ASCENTS
• Log them with no signal — record a send at the crag and it uploads by itself when you're back online. It shows up in your list right away, marked as pending.
• A card to share — logging a send builds a card with the climb's photo, its line, the grade and your name, in light or dark. Share it as an image.
• The quality rating you'd already given no longer gets cleared when the read fails.
SHARING
• Share a climb as its cactux.app link. And opening a link like that with Cactux installed takes you straight to the climb in the app.
PROFILE
• Notifications and Messages sit under your name, each with its own count.
• Review your guidebook's photos and videos from the app — it used to be web only.
AUTHORING
• Averaged coordinates — the location button folds several GPS readings together instead of keeping the first one, and shows you the ±N m as it settles.
• Clearing a climb's coordinates finally clears them.
• A connection hiccup no longer shelves what you wrote offline; it retries on its own.
ALSO
• Smaller markers on cover topos, on the card and full screen alike.
Thanks for climbing with Cactux.
2.7.0 Aug 14
Cactux 2.6.0 — topos.
TOPOS
• Turn the phone — a sector topo is a wide wall, and now you see it lengthwise, full screen.
• Tapping the photo works again — a line, an anchor or a number tells you which climb it is. It wasn't responding before.
• Line list — every climb on the topo in order, with its number and its grade. Find "the 5.12 on the left" without guessing.
• Smaller markers on cards — you see the rock, not a pile of white dots.
PROJECTS
• A project no longer reads like a grade: open projects in teal and closed ones in amber, with a striped line and a note that it belongs to someone else.
REFERENCE LINES
• Variants and neighboring lines on the climb's own photo — and now you can draw them from the phone, not just the web.
ALSO
• The community grade shows up in lists when it differs from the guidebook's.
• Log a route as a variant or an extension of another.
• Climb names use the whole line — no more "Calpu…" with half a row empty beside it.
• Fixes for your partner profile and a trip's forecast.
Thanks for climbing with Cactux.
2.6.0 Aug 12
Fixes for your partner profile.
• If you shared your location before creating your profile, it now actually lands: you show up on the map and distances are measured from where you are.
• The button on each climber's row no longer guesses while it loads — no more offering a request that could never send.
Thanks for climbing with Cactux.
2.5.1 Aug 4
Cactux 2.5.0 — partners, and the watch.
APPLE WATCH
Send a sector to your wrist and leave the phone in the pack. Trail navigation to the boulder, marking points and recording trails — all with no signal, from the watch.
OFFLINE
• Create sectors, routes, boulders and topos at the crag with no signal. They upload themselves once you're back.
• Suggest corrections to a guidebook that isn't yours — offline too.
• Record trails as you walk them, from the phone or from the watch.
• Save your own points: the car, water, shade. From the wrist as well.
PARTNERS
• Sessions: propose a quick outing, rock or gym, and confirm it with whoever's coming.
• Trips: invitations, join requests, shared expenses, gear lists, carpooling and the forecast for the destination.
• Follow climbers and see what they're sending.
• A notification feed so nothing gets lost.
ONE PROFILE, ONE INBOX
Your partner profile and your Cactux profile are now the same one. So are the two message inboxes.
GUIDEBOOKS
• Routes now appear on sector maps, not just boulders.
• Read grades in your own system: V-scale, Font, YDS or French. What the first ascensionist wrote doesn't change.
• Credit for the people who bolted and documented, plus community suggestions.
Thanks for climbing with Cactux.
2.5.0 Aug 2
What's new:
• Follow the approach trail: a new button centers the map on you and turns it in the direction you're walking, so you don't have to keep panning after yourself.
• While recording a trail, the map now turns with you too, and hides existing trails so you only see your own track.
• Empty sectors now show their empty state offline instead of loading forever.
• You can record a sector's boulder trail even when its first boulder was created offline.
Thanks for climbing with Cactux.
2.4.2 Jul 24
What's new:
• Automatic reconnection — if you lose your connection and it comes back, the app restores your session on its own, with no need to close and reopen it.
• More accurate approach-trail recording.
Thanks for climbing with Cactux.
2.4.1 Jul 23
What's new:
If you help document areas, you can now create and edit guide content right on the rock, offline:
• Field authoring — create and edit sectors, routes, boulders, topos, paths, and photos while you're at the crag, even with no signal. Everything syncs once you're back online.
• More accurate locations — when you capture a parking spot, sector, or boulder, we now wait for a reliable GPS fix instead of taking the first reading.
• Record the approach as you walk it and save it to the guide.
• Stability fixes across maps, recording, and offline downloads.
2.4.0 Jul 22
What's new:
• More reliable offline guides — downloaded guide photos no longer disappear when your iPhone runs low on storage, and a download is only marked ready when it truly is.
• Storage warning — if there isn't room for a guide, we tell you before the download starts instead of halfway through.
• Share your points — send a map point's location or copy its coordinates.
• "Navigate" always available — and when you're far from the area, you can now see the boulder on the map.
• Update notice — the app now tells you when a new version is live on the App Store.
• Fixes to the sector map and the trips list.
Thanks for climbing with Cactux.
2.3.0 Jul 14
What's new:
• Trips — Plan group outings with your partners: create a trip, invite others, and organize it all in one place.
• Boulder navigation — Waze-like guidance that works offline to walk you from boulder to boulder along the trails.
• Map points — Save your own points (parking, camp, water) that stay available offline.
• Explore mode — Roam the sector map with boulders colored by grade.
• Richer guides — Multipitch topos, highlighted variants, and tappable reference lines.
• Performance improvements across sector and discovery lists.
Thanks for climbing with Cactux.
2.2.0 Jul 12
Fixes and improvements in this release:
• Compas — Filters and "Share location" buttons now respond correctly to taps.
• Compas — You'll see more climbers in your list, including those who haven't shared their location yet.
• Compas — Location detection is more reliable when returning from other screens.
• Boulder map — When you're standing on a boulder, a label now shows its name so you know which one you're at.
• Boulder map — Tapping a boulder cluster while another card is open now correctly opens the cluster list.
• Guides — More accessible "Clear" button to reset filters.
• Boulder — New toggle to show/hide the line in the full-screen viewer.
• Grade filters — Use the community consensus grade when set.
• Ascents — "Send" is the new default style for new logs.
Thanks for climbing with Cactux.
2.1.1 May 19
What's new in this release:
• Refreshed Compas — New step-by-step onboarding, much richer profiles, photos, likes, sessions to plan trips, and reviews after climbing together.

• Fresh tab icons in our own block-print folk-art style.
• Small visual polish across cards, avatars, and community grade badges.
Thanks for climbing with Cactux.
2.0.1 May 6
Cactux is now much more than a climbing guide — it's a community. Find partners with the new Climbing Partners section, discover community-published events, read climbing news, chat with other climbers, and explore guides created by local climbers. Now available in English and Spanish, worldwide.
2.0.0 Apr 28
