01
What each movement cost.
Thrusters, pull-ups and the run scored separately instead of averaged into one number. You will recognise the one that is eating your score.
· VITROO BAND
It knows what you just did.
Every other tracker watches your heart rate and calls it functional strength training. Vitroo knows there were thrusters — so it can tell you what each one cost, how fast you came back, and where the round fell apart.

The problem
A curve is not a workout.
Forty-one minutes. Average 154. Peak 183. That is what every tracker on the market hands you after a hard session — and it is equally true of a Fran, a heavy back squat day and a bad night of sleep.
It cannot tell you the thrusters emptied you and the pull-ups were fine. It cannot tell you round three cost forty seconds more than round one. It never knew there were thrusters, because it was never told — and it can't ask, because most of the people wearing it aren't doing a workout at all.
How it works
You tell it. Then it tells you.
One thirty-second habit before you start is what makes everything afterwards possible.
-
01
Write the workout down.
Type it, pick a benchmark, or photograph the whiteboard and let it read the scrawl. Fran, a HYROX sim, or whatever your coach put up this morning.
-
02
Train. Leave the phone in the bag.
The band records the whole session on its own — through the run, the rower, the sled. No screen to glance at, nothing to tap between rounds.
-
03
Read it back movement by movement.
Because it knew the workout, it can find the workout in what it measured — every rep, every round, and every one of the gaps in between.
What comes back
Four things nothing else can tell you.
Not because the sensors are exotic — because it knew what you were doing while it measured.
02
How fast you come back.
The sixty seconds after a set say more about fitness than the sixty during it. Vitroo watches every one of them and shows the curve getting flatter as you tire.
03
Where the round decayed.
Rep speed, round by round. The moment your pace broke is a place on a chart, not a feeling you half remember on the drive home.
04
Your HYROX, station by station.
Eight runs, eight stations, and the roxzone nobody trains. Fixed format means your splits are comparable to every other race you have ever run.
Two sports
Both of them written down before you do them.
That is not a small detail — it is the whole reason this works. A general fitness tracker cannot ask you what you are about to do, because most of the people wearing one are not about to do anything in particular. You are.
CrossFit
Fran is always Fran.
The benchmarks do not move, so neither does the comparison. Vitroo lines this Fran up against your last one rep for rep — and against the recovery between rounds, which is the half of your fitness the clock never showed you.
Every round you finish, it watches the sixty seconds afterwards. When the curve stops coming back down, that is the round that beat you.
HYROX
Eight runs, eight stations, every single time.
The format never changes, which makes your splits comparable to every race you have ever run and to everyone you will ever line up against. Vitroo scores each station on its own, and it scores the roxzone — the transitions nobody trains and everybody loses time in.

The band
Wear it and forget it.
No screen, no notifications, nothing to swipe. It is a sensor you stop noticing by the second day — which is the only way a thing gets worn for the night as well as the session.
- 21 days on a charge, so charging is a monthly errand
- Swim, shower, sauna 50 m water resistant, and it stays on for all three
- Sleeps well 28 g, soft strap, no light in your face at 3am
- Works alone records a full day without your phone anywhere near it

Who we are
We are building the hard part.
Recognising movement from a wrist is not a solved problem, and everyone who has tried to solve it in general has failed. We do not solve it in general. We ask you what you are about to do, and then we only have to find it — which is a problem that has an answer.
That is the whole company: sensors, signal, and a sport with enough structure to be worth measuring properly. If that is the kind of thing you want to work on — hardware, firmware, signal processing, iOS — we would like to hear from you.
