What you stopped, what you started, and what it is all for.
The app
Today
One screen for the whole day: what you have stopped, what you have started, and what it has saved you so far. The pledge at the top is the only thing the app asks of you before the day starts.
The honest day
Every past day stays editable, forever. Miss a week and you can still fill it in truthfully. And on a day you genuinely could not, you say so — an amber day is skipped by the maths entirely, never counted against you.
The counter
It runs whether or not you are looking at it. Slip, and the counter restarts — but the run you just finished and your best ever are both kept. Nothing you have done is deleted for being interrupted.
The year
A year of days at a glance. Green for kept, amber for the ones you could not, blank for the ones still to fill in. Tap any square, however long ago, and put it right.
Countable habits
Not everything is a yes or a no. Some habits have a number — glasses of water, pages, minutes — and a day can be part done rather than failed.
What it is for
Quitting saves money. Point it at something real — a trip, a watch, a deposit — and watch the thing fill itself in while you carry on not doing the thing.
Your life
The milestones that actually mattered, and the ones still coming. This is the part that answers the question you ask yourself at three weeks in.
The account
Not a dashboard — a printed statement. Days, money, best runs and consistency, set out to be read rather than decoded.
01 — The promise
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, even when you did not. That is the reason this app exists.
Every past day stays editable, forever. Open a habit, tap any day in its heatmap, and put it right — a week later or a year later, it makes no difference.
A day has three answers, not two. Done, slipped, and an amber couldn’t that carries a reason. Amber days are skipped entirely: they cannot break a streak and they are not counted against your percentage. Break your leg and a three-times-a-week target shrinks for a fortnight rather than failing you fourteen times.
Owning a slip is one tap, and it is deliberately plain rather than alarming. The counter restarts from that day; the run you had and your best ever run both survive. Nothing is ever deleted for being honest.
02 — What it holds
The things you quit. A live counter down to the second, backdated to when you actually stopped. What you have not spent, and what you have not consumed — 940 cigarettes not smoked. For the habits where it is known, a recovery timeline of what your body is doing about it, and a panel that tells you which phase you are in today rather than only what is next.
Every claim in those timelines names where it comes from — the NHS, the CDC, the NIDA — or says plainly that it is commonly reported rather than proven. And where stopping suddenly can be genuinely dangerous, alcohol above all, the app says so before it shows you a timeline, not in a footnote. General guidance, not medical advice.
The things you took on. Current streak, best ever streak, and one tap to record today. Every day, chosen weekdays, or a number of times a week — and your consistency since the day you began. Things you do several times a day are counted rather than ticked: eight glasses of water fills up as the day goes on.
Goals, because the counting is not the point. A money goal fills itself from what the quit habits are no longer costing you, so the cigarettes you did not buy visibly turn into the thing you actually wanted.
Everything else in the app reports on a day that has already happened. This is the one thing you do before it: a promise, made in the morning, to the things you are stopping. Skipping it costs nothing and is not recorded — it is an offer, not another box.
Habits can be grouped into sets — work and personal, or whatever you call them — and the switcher narrows everything with it, so a work streak never dilutes a personal percentage. It stays hidden until you make a second set, because one set is not a choice.
Your figures set as a printed statement rather than a dashboard: the year at a glance, the patterns that the data genuinely supports, and nothing invented to fill a chart. Plus a shelf of the books and talks worth your time, each spine as thick as its reading time.
03 — Your data
There is no account to make and no server to sign in to, because there is no server. Everything you enter is written to a database inside the app on your own device, and stays there.
You can write your whole history out as a single file whenever you like, and read it back in on another device. That file is yours; it goes wherever you put it and nowhere else. Read the privacy policy — it is five lines long, for the obvious reason.
04 — Getting it
Days Strong is not finished yet. It is being lived with before it is sold, which is the only honest way to find out whether a habit tracker survives a bad fortnight. When it goes on sale, the link will be on this page.

iPhone and iPad. 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.
