At six in the morning you know
what the body is ready for.
Velín turns watch data, sleep and training load into one number. The coach sees the whole squad live, the athlete sees themselves — and both look at the same data.
- Cockpit for the coach
- iOS app for the athlete
- Apple Watch (HealthKit)
Who it's for
Velín doesn't know the sport. It knows the body.
HRV, resting heart rate, sleep and training load work the same way for a kayaker, a footballer and someone lifting in the gym. What changes between sports is the training plan — and that comes from the coach. That is why Velín is not tied to a single discipline.
The cockpit today runs canoe-sprint racers as well as strength training — you can see it in the screenshots below (Athlete A – D). Neither the method nor the app is tied to one discipline.
01 · Morning
One number, locked in the morning
Not a single number off a watch. Velín reads HRV and resting heart rate against the athlete's own baseline — not a population table — then adds sleep, yesterday's load and the subjective answer to a short morning check-in.
The value is locked in the morning, so the day can't be scored retroactively by how it turned out. The score runs from 1 to 99 and always comes with a breakdown: you see not just how much, but why.
02 · Through the day
Through the day you see what's left in the tank
Readiness is a morning snapshot. Energy is the film: a running estimate of what the body has left — it drops with load and stress, and recovers with rest and sleep.
So the coach sees not only whether the athlete could train in the morning, but also what the session actually took out of them.
03 · Weeks and months
Load you see before you feel it
Velín compares acute load over the past week against chronic load over the past month (ACWR). 0.8 – 1.3 is the optimal band, 1.3 – 1.5 elevated, above 1.5 a risk of overreaching. It also watches training monotony.
The athlete's detail view runs a form curve by week: fitness (CTL), fatigue (ATL) and their difference — form (TSB). Above −10 the athlete is fresh, −10 to −30 is loading, below −30 is risk. The coach sees where form is heading towards race day, not after it.
Negative form in a build block is normal and expected — it is fitness being paid for. It rises in the final week before the goal.
An honest note. Velín does not diagnose and does not replace a doctor or a coach. It is a tool that puts in one place what a coach would otherwise piece together from five different apps.
04 · Coach
The coach sees the whole squad, live
One dashboard, the entire squad. Morning readiness, HRV, resting heart rate, sleep and load for every athlete — colour-coded, so an outlier reaches you before you go looking for it. Weekly plans are editable right in the table and the athlete sees the change immediately. Runs in the browser — on desktop and on mobile.
05 · In the background
Data flows on its own, in the background
The athlete starts nothing in the morning. The watch measures overnight, the app picks the data up through HealthKit, and by the time the athlete sits down to breakfast the coach already has the number in the cockpit.
Where it runs
On iPhone today, more in preparation
Watches: Apple Watch via HealthKit today. Garmin watch support is in preparation.
Not a diagnostic tool. Velín does not measure blood pressure, glucose or anything the watch can't. It shows exactly the data it has and says where it comes from. It is not a medical device and does not replace a doctor.
Pricing
We build it, then we live on it
The setup fee is a one-off build of your Velín. The monthly fee keeps the data moving, the Velín alive and us at the other end of the phone.
Prices are excl. VAT; amounts incl. Slovak VAT (23 %) are shown with each item. The setup fee is one-off; the monthly fee is billed once your Velín is live. The same price list is on vassweb.com (Slovak).
