Made for your kind of movement.

Interface

A precision instrument you read at a glance.

Large numerals, one clear hierarchy and almost no motion. Built for a dark gym floor and just as sharp in daylight.

01
Every score shows its working

The inputs, the baselines they were measured against, and what the day was missing.

02
Reads Apple Health

HRV, resting heart rate, sleep, steps and weight, with nothing to type in.

03
Maps you can actually run

Sets, reps and weights logged as you go, carried forward to next week.

The Map

Not a PDF. A living plan.

A Map is a structured transformation plan with a version history, required check-ins and a real coach attached. It adapts as you progress, and every change is recorded.

The Terrifit Band

One band. Every version of you.

Continuous performance sensing for training, work and everything after.

Terrifit V1 woven performance band with its side-glance display
Woven strap

Two colours of yarn woven together, not one flat dye. It hides a hard week and dries flat in twenty minutes.

Sensor module

The whole computer, about the size of a thumbnail, sitting against the inside of your wrist where the signal is cleanest.

ECG contact

A second electrode on the outside. Rest a fingertip on it and the band records a single-lead trace to go with the optical reading.

No screen

Nothing to check, nothing to buzz, nothing to charge every night. The band measures and the phone explains.

    No screen

    Nothing to check, nothing to buzz, nothing to charge every night. The band measures and the phone explains.

01
Continuous sensing

Adherence, strength, cardio, sleep, recovery, activity, measurements and body composition — in one private dashboard, with weekly, bi-weekly and monthly comparisons.

02
Side-glance time

Large numerals, one clear hierarchy and almost no motion. Built for a dark gym floor and just as sharp in daylight.

03
4-dot battery

Health scores and body-age estimates always show their inputs and their limitations. They are fitness signals, not medical diagnoses, and Terrifit will never present them as such.

04
Woven for real life

A social app for everything you do for your body, the V1 band that tracks how you are actually doing, and a shop of supplements and gear we use ourselves.

What it measures

It reads you the whole time, and shows you its working.

Continuous sensing from the moment you fasten it. No session to start, no screen to check, and nothing to charge overnight for a fortnight.

Around the clock

Heart rate
Continuously, awake and asleep, not only during a workout
Heart-rate variability
Taken in your deepest sleep, which is when the number means something
Blood oxygen
Overnight SpO₂, and how you are adjusting at altitude
Skin temperature
Against your own baseline, never a population average
Breathing rate
Usually the first thing that moves when you are coming down with something

Worked out from those

Recovery
One morning score from HRV, resting heart rate, sleep and breathing rate
Strain
Cardiovascular load through the day, on a 0 to 21 scale
Sleep
Light, deep and REM, against how much sleep you actually needed
T Score
How much of the day you genuinely moved, out of 100
Fitness age
From your maximum and resting heart rates. Free, and shareable

While you train

Automatic sessions
It works out you have started and logs it. Over forty activities
Metabolic load
What the session cost, carried into tomorrow's recovery target
Stress and mood
Autonomic load across the day, not a single morning reading
VO₂max
Cardio-respiratory fitness, tracked as it moves
Heart rhythm recording
A single-lead trace on demand. A recording for your own records, not a diagnosis

Terrifit provides wellness guidance, not medical diagnosis. Scores and estimates are not clinical measurements. If something looks wrong, see a clinician.

One signal. Every version of you.

Ten languages

Native from the first day, not translated later.

Terrifit was built in ten languages at once rather than shipped in English and localised afterwards. Every screen, every score and every error message — including the ones you only see when something goes wrong.

One signal. Every version of you.

Arabic runs right to left with its own typeface, because a language is not a font swap. Country names and dates come from your device rather than a table we maintain, so they are correct in places we have never been.
