What each movement cost.
Thrusters, pull-ups and the run, scored separately — not averaged into one number.

you just did.
A screenless band for CrossFit and HYROX.

Why Vitroo
A curve is not a workout.
Forty-one minutes. Average 168, peak 191. That is what every tracker hands you after a hard session — and it is equally true of a Fran, a heavy squat day and a bad night's sleep. Vitroo asks what you are about to do. Then it can tell you what each part of it cost.
How it works
Written down first.
-
01
Write it down.
Type the workout, pick a benchmark, or photograph the whiteboard. About thirty seconds.
-
02
Leave the phone in the bag.
The band records the whole session on its own. Nothing to glance at, nothing to tap between rounds.
-
03
Read it back.
Every rep, every round, and the gaps in between — movement by movement.
What comes back
What it tells you.
How fast you came back.
The sixty seconds after every set, watched every time. When the curve stops coming down, that is the round that beat you.
Where the round decayed.
Rep speed, round by round. The moment your pace broke is a place on a chart, not a feeling on the drive home.
Your HYROX, station by station.
Eight runs, eight stations, and the roxzone nobody trains — comparable to every race you have ever run.
And every day, without asking: sleep, Zone 2 cues, training load, and Vitroo Read — answers made of your own sessions.
The band
Wear it, then forget it.
No screen, no notifications, nothing to swipe. A sensor you stop noticing by the second day — which is how it gets worn through the night as well as the session.

Questions
The ones people ask.
Do I really have to write the workout down every time?
Yes, and it takes about thirty seconds — type it, pick a benchmark, or photograph the whiteboard. That one habit is the difference between this and every other band: with it, the band knows the second round of thrusters from the first.
What if I forget?
The band still records the session — heart rate, movement, the whole day. You get the curve every other tracker gives you. Logging it late is better than not at all; logging it first is the point.
Does it need my phone with me?
No. It records a full day on its own and syncs when the two are next near each other.
Can I swim in it?
Yes. 50 m water resistant, and meant to stay on for the shower and the sauna too.
How often do I charge it?
About once a month — 21 days on a charge is the target. A band you charge nightly is off your wrist every night, which is exactly when it should be reading you.
Do I have to do CrossFit?
CrossFit or HYROX — both are written down before they are performed. Other training still gets heart rate, sleep and load, just not the movement-level read.
Is there an Android app?
In progress. iOS today.
What happens to my data?
It is yours. What we keep and why is written out in full in the privacy policy, and you can delete your account from inside the app.
Who we are
We are building the hard part.
Recognising movement from a wrist is not a solved problem. We don't try to solve it in general — we ask what you are about to do, and then we only have to find it. If sensors, signal processing, firmware or iOS is the kind of thing you want to work on, write to us.
