Now in TestFlight beta
Log your climbs in two taps. Understand how your body responds.
A climbing logbook on iPhone and Apple Watch.
I built the logbook I wanted for my own climbing. No sign-up to start.
Insight
Your logbook, with insight.
Logging has to be fast, or you won't bother. Insight takes time to be worth anything. CragMate does both.
Session insight
Heart-rate timeline, peak-performance window, personal bests — ready right after every session. No setup.
Long-term progression
Grade trends, volume by style, recovery patterns. The changes you can't feel session to session, but that add up over a season.
Yours to keep
Export to JSON or CSV any time. No account needed, no lock-in.
How it works
From chalk-up to logged, without breaking the flow.

Made to stay out of the way
Your whole climbing history, one glance.
Three small things I sweated — because they're what makes a logging app stick instead of getting deleted.
device · feature-crown apple-watch Digital Crown dial showing V4 with dashed crown-rotation hint ring.
Two-tap climb logging
Dial the grade. Tap the outcome. Done. The Digital Crown on Apple Watch makes grade selection feel natural.
device · feature-hr iphone Mini HR curve with Sunset-red peak marker dot.
Heart-rate timeline
Every attempt overlaid on your heart rate. Spot your peak-performance window. Know when you're cooked.
device · feature-trend iphone Grade trend line in Ice gradient.
Progression, over time
Grade trends, volume by style, where your weak spots actually are. Built up quietly while you climb.
On the wrist
Logging that doesn't leave your wrist.
Most climbing apps stop at the phone. CragMate lives on your wrist, where your hands already are. Rotate the Digital Crown to pick a grade. Tap Send, Flash, Onsight, or Attempt. Always-On stays readable between burns without draining the battery. Your session syncs back to iPhone the moment you untie.
- 01 Digital Crown grade picker. Monochrome dial, haptic on every click.
- 02 Three-page swipe: grade → outcome → pause. Never hunt for the button.
- 03 Always-On at 0.1 Hz — readable between burns, easy on the battery.
- 04 Offline-first. Sync when you're home.
device · watch-grade-picker apple-watch-large Grade picker: 14:32 in amber top-left, ●143 in red top-right, 'Grade' label, massive V4 in monochrome cream, dial indicator, outcomes row with Send highlighted.

Questions climbers ask
The ones we actually get.
Email me if yours isn't here — I answer every one personally, and the answer usually ends up in the next build.
How do I get CragMate right now?
It's in TestFlight beta. Tap any "Join the TestFlight beta" button, install Apple's free TestFlight app if you don't already have it, and you're in — free while it's in beta. You'll need an iPhone on iOS 18+; the Apple Watch app (watchOS 11+) is where two-tap logging lives, but it's optional. No account, no sign-up.
Does it work offline at remote crags?
Yes — everything works offline, no signal needed. Céüse, Siurana, the middle of nowhere in the Bugaboos — the watch logs it either way. Getting it onto your phone doesn't need the internet either: Watch and iPhone sync directly over Bluetooth/Wi-Fi once they're near each other again, not through the cloud.
Can I import from Mountain Project, Kaya, or 27 Crags?
Not yet. CragMate can export your sessions to CSV or JSON any time, but there's no import from Mountain Project, Kaya, 27 Crags, or anywhere else today.
Which grade scales are supported?
V-scale, Font, French, YDS, and custom scales. Pick one or three — CragMate shows them side-by-side on every climb.
Android?
Not yet — iOS + watchOS at launch. Tell me if you want it. Demand is how I prioritize.
Log enough climbs, and the pattern shows itself.
I built it for my own climbing. A handful of beta testers are shaping the rest. There's room for you.
Free while in beta. iPhone + Apple Watch.
