PRE-LAUNCH
"I'll start Monday."
How many Mondays has it been?

You're not lazy.
You're deciding too late.

A three-minute check-in on your commute. We remember the plan; you just show up. You don't skip the gym at the gym door. You skip it on the ride home, before you ever get there. On day one, we find the point where your plan breaks.

HOW IT WORKS

What it actually looks like

DAY ONE — whenever you download it
A 20-second walkthrough — it starts on its own in a moment
9:41•••
Way HomeSetting up · Evening workout
Today we set
one hypothesis.

Not a finished plan. Give us ten minutes, try it three days, then we fix what's off.

We're after one thing — the point where your evening splits from the plan. For one person it was the station exit. For someone else, stepping into the shower.

Two days that didn't happen, laid side by side — usually that's enough to find the point where yours splits. That's what day one is for: not talking you into it, but settling exactly when and where you'll go.

EVENING — on the train, one stop before yours
"Your stop is next. Straight to the gym — don't go home first. That's the only thing you have to do today."

No pep talk. You decided this before you got home, so there's nothing left to argue with yourself about.

At 7pm, when it's actually time to go, we send you nothing.
That's deliberate. People who only worked out when their phone buzzed stopped working out once the reminders stopped. What gets you there should be the plan you made on the train, not an alert.
NEXT MORNING — one tap
8:12•••
Way HomeMorning check-in
You were at the gym
last night at 7:15 — right?
That's three times this week.
Tap one — on the days you did it, the screen fills with color

We remember the plan so you don't have to. You just tap once. Color appears only on the days you did it. On the days you didn't, nothing happens — and we don't lecture you about it.

Working out is just the example. Reading, walking, cutting back on late-night takeout — it works the same way.

WHY THE LAST ONE DIDN'T STICK

You've tried this before.
Here's why it didn't stick.

01
"I'll start Monday" — deciding you want itIn one study, people who simply wanted to exercise made it 38% of the time. People who decided in advance exactly when and where made it 91% of the time.
02
Reminder apps — used for three weeks, then forgottenPeople who worked out because their phone told them to stopped working out when the reminders stopped. A notification can get you there today. It can't turn it into a habit.
03
The 21-day ruleResearchers at UCL tracked 96 people every day. It took 66 days on average for a habit to become automatic — 18 days for the fastest, 254 for the slowest. Nobody can say where "21 days" came from.
04
One missed day, and you feel like you've blown itIn that same study, missing one day made no difference to whether the habit stuck. What ruins it isn't the missed day — it's deciding it's already ruined.

The people who made it stick
did three things differently.

1
They decided when and where in advance.Not "I'll work out more," but "off the train, straight to the gym."
2
They didn't clear out new time for it.They attached it to something they already did every day — the ride home.
3
When they missed a day, they went again the next day.What builds the habit isn't a perfect streak. It's going back after you miss.

Those three things are what this app does for you every day. Here's what that looks like.

YOUR CALENDAR

This app is black and white.
Color appears only on the days you did it.

Every day you follow through, the screen fills with color, and that color stays on your calendar. Each square is one window: the days you did it keep their color, and the days you didn't stay white.

A white pane = a day you didn't do it
A calendar you colored in yourself.
GRADUATION
And at some point, we're
the ones who say it:
"You don't need us anymore."

Once you've gone often enough on your own, with no reminders from us, we're the ones who bring up cancelling. It means the habit stuck. That's what success looks like here.

01
One habit at a time, not five.We start the next one only after the first has stuck.
02
Expect it to take two or three months.In the UCL study it took 66 days on average, so we plan for 13 weeks.
03
We don't hide the cancel button.We also publish the three criteria we use to decide you no longer need us.
04
We don't talk much.Three minutes in the morning, three on the way home. Nothing in between.
THE THREE CRITERIA WE USE

One — when how automatic it feels stops climbing in week three. That's as far as it goes.
Two — when you go at least 8 times out of 10 across the days we said nothing and the weekends.
Three — when, over the last four weeks, you came back at the next chance every single time.

PRICE

You are not paying anything now. Signing up is free and we don't take card details — the price below applies after launch.

First two weeks free
then $6.99/mo
  • Cancel anytime
  • 13 weeks by default — usually three charges, about $21 in total. Less than one session with a trainer

It's a monthly subscription, but the cost has an end. Once the habit sticks, we're the ones who bring up cancelling.
Some people finish sooner, some take longer — the measurement decides when it ends, not us.

EARLY ACCESS

We're looking for people to start with.

This is a pre-launch signup. When it opens, you're first in — two weeks free.

A GOOD FIT

  • You take a train or bus at roughly the same time each day
  • The hour after work is usually yours
  • The habit comes after the ride home — a gym, a walk

WE CAN'T DO THIS YET

  • You work from home or drive — there's no ride home to build on
  • Your evenings are committed to family
  • The habit only works in the morning — that's a later version

Sign up anyway. We'll tell you when it fits.
