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.

01Start

CragMate on Apple Watch - pick session: Boulder Indoor, Boulder Outdoor, Sport Indoor

iPhone picks it up.

Recovery, not zones

Heart-rate zones lie to climbers.

Isometric contractions and arms-over-head positions inflate your heart rate - a zone chart can't tell trying hard from hanging on. So CragMate tracks the number that actually predicts your next attempt: how fast you recover between burns.

Fatigue curve

Watch it build across the session, attempt by attempt.

Ready rate

How often you pulled on actually recovered.

Rested vs. rushed

Your send rate, both ways. Spoiler: rest more.

On the wrist

Your hands are on the rock. Your logger should be on 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.

Questions climbers ask

The ones I actually get.

Email me if yours isn't here - I answer every one personally, usually within two or three working days, and the answer often ends up in the next build.

How do I get CragMate?

It's free on the App Store. You'll need an iPhone on iOS 26+; the Apple Watch app (watchOS 26+) 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, set per session type - boulder in Font, clip bolts in French. CragMate never converts between them: a grade you logged in Font stays Font. Guessing that 7A is "about V6" is how a logbook quietly rewrites your history.

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 shaped the first release. Now it's live on the App Store.

Free. iPhone + Apple Watch.
