Day2 — small actions, steady days

The situation

Parkinson's is the fastest growing neurological condition in the world, and there is no go-to digital provider for managing it.

Movement is medicine

The evidence is settled. The delivery is not.

Structured exercise improves motor and non-motor symptoms and helps medication work better. Almost nobody with Parkinson's has a way to actually do it, at home, on an ordinary Tuesday.

Exercise isn't optional, it's essential.

It's safe and feasible to exercise at high intensity.

I have nothing but choices about how I react to it.

The app

Four things that change the day.

Open it in the morning, say how you're moving, and Day2 does the deciding. No streaks to break, and no guilt on the days you can't.

Real screens, captured from the app testers are using today.

The bit people don't expect

Someone to ask, at four in the morning.

Parkinson's is relentlessly specific and often lonely. Most questions feel too small to trouble a nurse with, and too big to sit with alone.

Marty is built into the app. He knows how you move, what you're working on and where you are, so the answer fits you rather than the internet. He will never discuss medication or doses — that stays with your clinician, and he says so.

Ask him anythingSymptoms, food, sleep, what to do on a bad day. In plain English, at any hour.

Safe by designMedication questions are refused and redirected before they ever reach the AI. Nobody at Day2 reads your conversations.

Who's building it

One of us has Parkinson's. The other one trains him.

We met at Ed's gym. The rest is history.

Matt Ross

Founder

Twenty years in advertising, eight of them as YouTube's Global Head of Brand. Diagnosed with Parkinson's nine years ago. Day2 is the thing he went looking for the week after diagnosis and never found.

Ed Shaw

Co-founder · Movement

Fifteen years training people with neurological conditions. Every session in Day2 comes from work he has done in a room with real people, on their good days and their off days. He and Matt met at Ed's gym.

Try it

You can start this morning.

Day2 is in open trial. It's free while we're testing, it runs in your browser on any phone, and it takes about five minutes to set up. There's nothing to download and no card to enter.

What you getA session built around how you're moving that day, food guidance, information chosen for your stage, local classes near you, and Marty.

What we can seeHow often the app is used. Days active, sessions and minutes. That's how we know whether any of this is working.

What we can't seeYour check-ins, your symptoms, your conversations with Marty, your photos, or anything about food. Those stay on your phone.

Open Day2 on your phone

Point your phone's camera at the code — Day2 is built for a phone, and the desktop version won't do it justice. Open it in Safari on iPhone or Chrome on Android, then add it to your home screen.

There's a short guide with pictures if you'd like the screens explained first.

Scan to open on your phone

It isn't finished. Tell us what's wrong with it — that's the part that helps.
