What is it
actually costing you?

Pick the one you are thinking about and put in what you really get through. Nothing is sent anywhere.

£5,844

A year of not smoking

That is £16 a day you would not have noticed going.

The full breakdown for smoking

Days Strong on iPhone: today

Today

Every day you didn’t.
Counted honestly.

The whole day on one screen. What you stopped, what you started, and what it has saved you.

Days Strong widgets: a ring that fills through the day, on the home screen

On your home screen

A ring that closes
every single day.

The count in your habit’s own colour, and a ring that fills as the day goes by and closes when you have earned another one. Small, medium and large — and the large one adds up what all of it has saved you.

On the lock screen too, where iOS draws every app’s widget in one colour.

Days Strong on iPhone: the honest day
Days Strong on iPhone: the year

The honest day

Forget a day.
Keep the streak.

Every past day stays editable, forever. Green for kept, amber for the ones you couldn’t. Amber is skipped by the maths entirely and never counted against you.

Days Strong on iPhone: countable habits

Countable habits

Eight glasses.
Counted, not guessed.

Some habits have a number. A day can be part done rather than failed.

Days Strong on iPhone: choosing a habit
Days Strong on iPhone: picking a mark

Setting one up

Ready to go,
or make your own.

Smoking, alcohol, sugar, gambling, doomscrolling, each with a real daily cost built in. Or start blank, name it yourself, and pick from 105 hand-drawn marks. No emoji anywhere.

Days Strong on iPhone: the Work set, with everything else filtered out
Days Strong on iPhone: the same day in the Personal set

Two lives, one app

Work here.
Home here.

Group habits into sets and switch between them. The counts, the streaks and the percentages all narrow with it, so a work streak never dilutes a personal one. The switcher stays hidden until you make a second set.

Days Strong on iPhone: the reading list
Days Strong on iPhone: Ban yourself, the gambling self-exclusion schemes

When willpower is not the answer

Something to read,
and something to do.

A short library on what actually happens when you stop, every claim naming its source. And Ban yourself: the UK self-exclusion schemes, the helplines, and a letter already written for closing an account — so the hardest thing to do is one tap, not an afternoon.

Days Strong on iPhone: the counter
Days Strong on iPhone: a goal filling itself

What it adds up to

A counter that never lies,
and money that becomes something.

The counter runs whether or not you look at it, and your best-ever run survives a slip. What you are not spending fills a goal you actually want.

Days Strong on iPhone: the Habits tab, every habit drawn as a wall of days

Every habit

All of them.
Every day.

Your habits have their own place: each one drawn as a wall of days, one under the other, so the one that is slipping shows itself without you opening anything. Tap any day to put it right.

A Days Strong poster: 427 days strong, Smoking, GBP 6,844 not spent

Something to show

Four hundred days
is worth saying out loud.

Make a poster of any figure and keep it, or send it to whoever has been asking how it is going. It saves to your phone like any other picture. Nothing is posted anywhere, and there is no feed to post it to.

Days Strong on iPhone: the last twelve months, drawn as a square for every day
Days Strong on iPhone: the account

The long view

A year of days,
all at once.

Twelve months as one square a day, then a printed statement of everything so far — the days you kept, your longest run, and what it saved you. Nothing invented to fill a chart.

Also on iPad

The same app.
More of it at once.

Your habits beside your figures, the last four weeks beside the counter, and what you have saved beside the thing it is paying for. One app, one purchase, both devices.

Days Strong on an iPad held landscape: Today, with the money at the top, the week of sleep across the middle and the habits in two columns below
  • Days Strong on iPad held upright: Today, with the habits in two columns

    Or hold it upright. The same screen, the same two columns, more of the list at once. It is one app that fits whichever way you are holding it.

  • Days Strong on iPad: a habit, with the counter, the last four weeks and the badges together

    428 days, and how you got there. The counter, the last four weeks and every badge on one screen instead of three scrolls.

  • Days Strong on iPad: a goal, with the money on the left and the habits paying for it on the right

    What it is all for. The money on one side and the habits paying for it on the other, so you can see which one is doing the work.

  • Days Strong on iPad: the account, every figure on one page

    The whole account. Every figure printed on one page. Nothing invented to fill a chart.

01 · The promise

The honest day

Forgetting to open the app never costs you a streak.

Most trackers quietly punish you for not opening them. A day you did not log becomes a day you failed. That is the reason this app exists.

  • Every past day stays editable, forever. A week later or a year later, it makes no difference.
  • Three answers, not two. Done, slipped, and an amber couldn’t. Amber days are skipped entirely, so they cannot break a streak or count against your percentage.
  • Owning a slip is one tap, and deliberately plain rather than alarming. The run you had and your best ever both survive.

02 · The app

What it keeps

  1. 01

    Stopped

    A counter running to the second, what you have not spent, and what your body is doing about it. Every claim names its source. Work out what yours is costing you.

  2. 02

    Started

    Streaks, your best ever, and days you can count rather than just tick.

  3. 03

    Sleep

    Type a night in or read it from Apple Health. No streak, no badge, no way to fail at it.

  4. 04

    The wind-down

    Say when you have to be up and how much sleep you want, and it tells you when your evening should end.

  5. 05

    Goals

    The money you are no longer spending fills the thing you actually wanted.

  6. 06

    The account

    Every figure on one page, and nothing invented to fill a chart.

03 · Your data

It never leaves the phone

No account, no server. Everything you enter is written to a database inside the app on your own device.

Write the whole history out as a file whenever you like and read it back on another device. The privacy policy is five lines long, for the obvious reason.

04 · Getting it

Free to start. One payment if you want more.

3 habits and 2 goals are free for as long as you like, and everything you have already recorded stays free to see, edit and export whatever you decide.

£4.99 once unlocks unlimited habits, the goals your money feeds, and the home screen and lock screen widgets. Not a subscription, and it never becomes one.

Apple Health is free for everybody — steps and sleep, both optional, both off until you switch them on.

There is no web version and there will not be one. The app is meant to sit on the home screen of the device you actually carry.

Free · no download

Read before you
decide anything

  • What happens when you quit — a timeline for smoking, drinking, vaping, sugar, caffeine and more. What changes, when it changes, and the source on every line.
  • What it is costing you — put in what you really get through and see it over a week, a year, or the next ten.
  • Where you are now — one day, 30 days, a year. What has actually changed by each point.
  • The things you are starting — how a streak survives the days you could not, and what an extra day counts for.
  • Sleep — a month of nights, no streak, nothing to fail.
  • What it is all for — the money, pointed at something you actually want.
