Klatos is a habit app built on its own metric: Habit Strength. A streak resets to zero the moment you slip; Habit Strength bends when you miss and recovers when you return. It's a living score for every habit, built to survive real life. Your only job is to come back. Klatos. Track the day. Change the year.
One missed day and weeks reset to zero.
One missed day dips, then recovers as you return. Simulate it →
The refusals
The thinking, in long form
If you only read one, read the first — it's the whole product in one argument.
A life is built out of days, and a day is built out of the small acts you actually perform in it. The whole product follows from taking one old line seriously.

Habit Strength reads how deeply a habit is built into your life, over a recent window that always ends today. Show up and it grows. Miss and it eases back, the way a muscle softens after rest. The days behind it still count. Come back and it climbs again.
Most habit apps are built for the version of you that never slips. Klatos is built for the one that does — because that's the only version that actually exists.
Track a habit long enough and it stops being something you do. It becomes something you are. That transformation doesn't come from a heroic week; it comes from small, honest marks repeated across a year. Klatos exists to protect those marks — and to keep them true.
Nous sommes ce que nous répétons chaque jour. We are what we repeatedly do.
If who you are is what you repeat, then a habit record has one job: tell the truth about what you actually repeated. The moment that record can be edited, gamed, or bought back, it stops meaning anything — and so does the self-knowledge it was supposed to give you.
That's why the most important design decisions in Klatos are the ones that keep the record true.
The shape of a practice
One number for everything tells you very little. In Klatos you group habits into spaces — Health, Mind, Work, whatever your life actually has — and each keeps its own score, its own heatmap, its own history. Each area rises and falls on its own terms, instead of one average that hides them all. The same habit can sit in more than one space, and count for more where it matters more.
A space is scored as the share of the day you actually kept. Miss one habit out of five and the day reads for what it was — the four you kept and the one you didn't. And a habit you finish on a day it wasn't even due can only lift the score, never lower it.

Klatos is the first product from Vixoris. We engineer software for work that compounds — lattices of small, consistent wins that hold weight over time. A habit app that turns small daily steps into a changed year is exactly the kind of structure we exist to build.
Sign-in is handled by Vixoris' shared identity, so your account is yours across everything we make. And the promises on this page are easy for us to keep, because they follow from the principle the company is built on: only what's true compounds.
A cathedral isn't cast in an afternoon. It's laid, one stone at a time.
Support
Klatos exists to help you build and track daily habits that compound into a changed year. Some of its choices are opinionated — you can't edit yesterday, you can't buy back a missed day. Each one comes from what the research says about consistency, compounding, and how far willpower alone can carry you. We're still learning. Tell us where we got it wrong.
No support tier, no ticket queue — write to us and the person who built Klatos answers. Real questions get real answers, including “not yet” when that's the true one.
Why measure the practice, not the outcome? Why can't I buy back a missed day? The help pages explain both the rule and the reason.
