## What is Kruin?

Built for climbers who train like athletes.

Kruin is your entire climbing life in one native app — every session, every board send, every finger workout, every rehab note — logged, searchable, and yours forever. This is the full native Kruin experience: fast, offline-first, and built for the phone in your chalk bag.

TRACK EVERYTHING
Climbing sessions, board sends, finger training, gym work, cardio, rehab. Nine-plus session types, all in one place. Log at the gym, on the wall, or on the couch — the app works fully offline and syncs when you're back online. A complete copy of your training lives right on your phone.

SEE PATTERNS
AI-powered weekly summaries and 90-day cycle analysis that actually understand climbing. Know not just what you did, but whether it's working. Personal records, grade progression, finger-strength trends, and injury history — the longer you train on Kruin, the smarter your data gets.

RECOVERY THAT MATTERS
Connect WHOOP and see your recovery, sleep, and strain right alongside your climbing. Your training analysis factors in how recovered you actually are — because a hard session on a red-recovery day isn't the same as one on green.

BRING YOUR BOARDS
Import your sends from Crux and Tension Board straight into your log. Your spray-wall and board climbing counts as training too — and it all lives in the same history.

TRAIN WITH YOUR COACH
Link with your coach and work from the same picture. They see your real training data; you get their programmes and notes. No more scattered text-message updates.

YOUR DATA, FOREVER
Export everything in one tap as an open, documented file — no account required to read it. We've never deleted a user's data without their request, and we never will.

Kruin is a focused tool for climbers who are serious about getting stronger. No ads. No tracking. No selling your data. Just your training, understood.

Athlete Pro subscription unlocks AI training analysis, WHOOP integration, and media upload. A free web tier is available at kruin.app.

## Version history (last 3 releases)

### 1.5.7 — 2026-08-12

Your KruinScore just got smarter.

We recalibrated the scoring engine with our coaching community, and every score and personal best has been recalculated under the new system — history included, so your trend is honest end to end. If your numbers moved, that's why.

• A flash now earns its bonus everywhere — board, gym, or rock
• An outdoor send always outranks a board flash of the same grade, no matter how many attempts the project took — projecting is never punished
• A much gentler attempts penalty: your hardest-fought sends finally score with honesty
• Sends inside an execution circuit earn a performance bonus
• One entry per named climb in your top ten — breadth builds the card
• Onsight has retired from the style picker; historic onsights keep their value, scoring as flashes

Also in this update:
• Chart range control — view your score and training trends over 12, 24, or 36 weeks, on your dashboard and in coach views
• Score-card accuracy fixes: 12-week averages stay pinned to twelve weeks, and sparkline labels stay readable at full depth
• Redesigned share cards
• Assorted polish

### 1.5.6 — 2026-08-09

• Coach-shared session templates now bring their circuits with them — accept a share and the circuit is ready to climb
• Board imports no longer re-offer climbs you've already logged
• Import review answers are now remembered across syncs
• Scoring now counts every grade, including V-scale-logged and beginner climbs
• Small fixes and polish

### 1.5.5 — 2026-08-04
