Field tools Free climbing and bouldering tools
Small, fast tools for boulderers — the ones we kept wanting on our own phones between attempts. Nothing to install, nothing to sign up for.
Bouldering Pyramid Builder
Count your sends by grade, find the tier you skipped, and get the session plan that fills it. Prints to one page.
Open the builderV Scale to Font Converter
Both directions, the full VB–V17 chart, and a plain answer for every single grade — each one with its own link.
Open the converterWhat Every V-Grade Feels Like
V0 to V14 described in movement rather than numbers: how long each usually takes, and what stops people getting there.
Open the grade explorerGym vs Outdoor Grades
What your gym number is actually worth on rock. Three questions, an honest range, and the arithmetic shown so you can argue with it.
Run the checkChalk Bucket Size Calculator
Tick what you carry and get the litres your session needs — before you buy a bag that turns out to be a chalk pot with a lid.
Open the calculatorYour First 90 Days
Everything we have written, in the order it becomes useful. Four phases, one page, no course and no email wall.
Start herePut these on your phone
Add the tools to your home screen and they open like an app — full screen, no browser bars, and the grade converter works with one hand between attempts.
Which one do you need?
Six tools, six different questions. Pick by the one you are actually asking:
- Stuck at a grade? The pyramid builder finds the tier you skipped
- Reading a European topo? The converter
- Wondering how hard a grade really is? What every V-grade feels like
- First trip outside coming up? The reality check, so the grade drop does not ambush you
- Buying a bag? The size calculator
- Brand new to this? Your first 90 days
Why we give these away
We sell one thing: a bouldering chalk bucket. That's it. Everything else we make — these tools, the guides in Field Notes — is free, ungated, and stays that way. No email wall, no trial, no "unlock the full version".
The honest reason: we're a new brand and nobody has heard of us. Building something climbers actually use is a better way to earn attention than buying it. The self-interested version is that some of you will eventually need a chalk bucket. Both are true.
What we're building next
One tool at a time, in the order they'd be useful. If there's a calculation or a chart you keep redoing on your phone in the gym, tell us — that is how most of these got picked.
Made by climbers, for climbers — here's who we are.
