For people who sit all day

More energy, sharper focus — in 90 seconds of movement

Long stretches of sitting drain your energy and dull your focus. Stirr breaks them up with short, guided movement — a gentle nudge, 90 seconds, back to work feeling sharper.

Free · no card · iPhone, set up in two minutes

What you'll actually see

No dashboards. No scores. No streaks to keep. Just the next small movement, at a kind moment.

How it works

You set it up once. Stirr handles the rest.

1

Tell Stirr when you work

Your hours, how gentle a rhythm you'd like, and whether you're at home or in the office — so the movements suit where you are. Takes about two minutes.

2

Get a nudge when it's time

A quiet notification. One tap and you're moving — and if you're mid-flow, it'll simply wait.

3

Move for 90 seconds. Carry on.

A few simple guided movements to get your blood flowing — then straight back to what you were doing, feeling sharper.

no equipment, no floor space, no changing clothes — just you, wherever you're working

Where this goes next

A workout doesn't cancel a day of sitting

Even a tracker that senses you move is built to aggregate — your day rolled into one total, ticked off and done. Here's a whole working day on one line.

Both say "you're good" — but here, an early workout closes the tracker's ring by mid-morning, then it goes quiet. Stirr says it each time you've actually just moved, all the way to five o'clock.

The Stirr device

Worn where sitting actually shows

The free app already keeps you moving through the day. The device is where Stirr goes further — a small sensor on your shoelaces, worn where stillness can't hide, so it never has to guess.

Nudges only when you've truly been still

It senses when you've genuinely been sitting too long, so a nudge lands right when you need it — never while you're already up.

Tells you when you've done enough

It feels the movement happen — so "you're good now" actually means something, and you can sit back down without wondering.

Pays attention so you don't have to

It senses all day, quietly — and never hands you a dashboard, a score or a streak. Wear it, forget it, let it do the minding.

No payment now — register interest. We're aiming to ship in early 2027, once enough of us are in. Expected price: around £80. We'll only email you about the cohort — see our Privacy Policy.

Why it matters

Why breaking up sitting matters

Informed by research into breaking up long periods of sitting.

It's the unbroken stretch that counts

Research keeps pointing the same way: it's not just how much you sit in total — it's how long each unbroken stretch lasts. Frequent short breaks do something a single long walk can't.

Keep your circulation moving

Long spells of stillness let everything settle. Brief, regular movement helps keep your blood moving — and that's where you feel it.

Steadier energy through the afternoon

The 3pm slump isn't compulsory. Little and often keeps you feeling sharper through the day than one burst of exercise at dawn.

"Lockdown cut my daily steps from 12,000 to 6,000. I could feel the difference — less energy, worse focus, just sluggish. So I built something to keep me moving through the working day. Now I rarely hit 3pm feeling foggy."

Questions

How long do the movements take?

90 seconds to start. Over time, Stirr gently guides you towards three-minute sessions — always simple, always back to work straight after.

Do I need any equipment?

No. Every movement works in normal clothes, in the space next to your desk. No mat, no weights, no changing.

What if I'm not very fit?

Stirr starts gentle and stays kind. The movements are simple — the point is breaking up the sitting, not breaking a sweat.

Can I do this in an open-plan office?

Yes. Tell Stirr you're at the office and it keeps the movements discreet — small enough that no one will notice. No floor space, no changing, nothing that turns heads.

Can I control the nudges?

Completely. You set the hours and the rhythm, and a nudge is always an invitation — ignore one and nothing is lost, nothing is counted against you.

What does the app cost?

Nothing. The app is free — sessions, nudges, all of it.

What will the Stirr device cost?

We expect around £80 for the founding cohort. The price is confirmed before anything is built — and you pay nothing until then.

When can I get the Stirr device?

It isn't shipping yet. We're building the first batch for a founding cohort — we're aiming to ship in early 2027, once enough of us are in. Register your interest (no payment, no commitment) and we'll be in touch the moment it's on its way.
