THE MAP GETS YOU TO THE BOULDER.
THE TOPO GETS YOU TO THE CLIMB.
BitLost is a map and logbook for Swiss bouldering.
It helps you find the area, the sector, and the right block without spending forty minutes walking around a forest confidently approaching the wrong piece of rock.
It intentionally stops there.
01 / A MAP. DELIBERATELY NOT A TOPO.
BitLost is not trying to replace guidebooks, local topo makers, first ascensionists, developers, photographers, or the people who have spent years cleaning, documenting, grading, maintaining, and making sense of these places.
That work matters. It is the reason a climbing area is more than a collection of rocks in a valley.
So BitLost does not provide exact per-climb coordinates, line-by-line pins, digital replicas of official topos, or a fluorescent shortcut around the actual fieldwork.
The topo does the important part.
It tells you what you are standing beneath. It gives you the line, the context, the approach notes, the local knowledge, and the work behind the climb.
Bring the topo. Buy the topo. Respect the topo.
BitLost is the useful thing before the useful thing.
02.1 / FIND THE RIGHT BOULDER.
BitLost shows climbable rocks on a very serious Swisstopo map.
Search by climb name, block, sector, or area. Switch between topographic and aerial imagery. Use the map to understand where you are, where you are going, and why the approach looked much shorter on the screen.
Pins lead to blocks, not individual lines.
That distinction is deliberate. BitLost gets you to the right block. Finding the line is part of the fun — for everything else, you still need the official topo.
As intended.
Currently covering Brione, Chironico, Cresciano, Gotthard, Magic Wood, and Murgtal: 5,984 climbs across 1,172 blocks.
02.2 / REMEMBER THE IMPORTANT PART.
Once you have found the rock, BitLost keeps a record of what happened next. Save climbs. Log sends, attempts, notes, and dates. Everything stays on your phone. No account. No feed. No performance theatre. No requirement to make a 6B look like a personal branding exercise. Just a private logbook for the climbs you did, the climbs you nearly did, and the ones that briefly made you question whether indoor climbing might be enough.
02 / HOW IT WORKS
THE MAP STAYS.
THE REST SLIDES UP.
Choose an area, understand the terrain, find the block, then put the phone away before it becomes another piece of climbing equipment with a charging problem.

01
CHOOSE YOUR AREA
Pick the place you are heading to. No account required. No ceremonial onboarding ritual.
-
02
READ THE TERRAIN
Browse sectors and blocks on official swisstopo maps. Switch between topo and aerial imagery when the approach begins to look suspiciously optimistic.
-
03
SEARCH OR BROWSE
Find climbs by name, grade, sector or block. Or browse until something looks suitably unreasonable.
-
04
FIND THE BLOCK
BitLost takes you to the boulder, not the exact line. The distinction is deliberate.
-
05
LOG THE SEND
Record style, attempts, date and notes. Private, local and free from inspirational captions.

06
KEEP THE USEFUL BITS
Save favourites, revisit projects and keep a quiet record of what happened.
