Notice how you're doing — before it becomes unmissable.
Yourni — say it like journey.
Yourni asks you briefly each day how you're feeling. On a bad day one tap is enough; on a good day there's something worth talking about. Out of both, a picture of your state builds up over time — and when the picture shifts, you'll see it.
Decline gets normalised.
Less energy, broken sleep, more worry —
a little more each day, so nobody notices until it's already bad.
Growth doesn't accumulate on its own.
A good week, the thing that
helped, the person you breathe easier around — it passes unnoticed and is
lost unless something brings you back to it.
The warning signs are always there. Motivation slipping, sleep breaking up, worry climbing, contact with people thinning out. But they accumulate slowly and are easy to explain away. Most people seek help only once they're already in distress.
You can't see it from the inside. You judge how you are by how you feel right now, and today always looks like normal. It cuts both ways — it's just as easy to miss that the last month has gone better than you expected.
Yourni collects the signal from somewhere else — a short, natural conversation. No forms, and no sense of being examined.
How it works
Three steps, a few minutes a day
Mental health difficulty turns small tasks into large ones. So every decision in Yourni is built to need the least effort at the moment you have the least of it.
Tap how you feel
Tap the map of feeling roughly where you are right now. There's no list to pick from and nothing you have to name — just set how strong it is. You put a word to it only if you want to.
A few secondsHave a short conversation
The assistant picks up where you left off together, then follows the thread of what you say. Short answers are fine. You can end it whenever.
About two minutesA picture builds up
Each check-in adds a piece: how you've been, what's going well and what isn't — sleep, energy, mood, appetite, the people around you. After a few weeks you can see which way things are moving.
ContinuouslyHowever you're doing
It adjusts to where you actually are
Yourni isn't an app for a crisis that makes no sense to open otherwise. It reads how you're doing and changes its pace and depth accordingly — from a single tap to a conversation that goes somewhere.
On a hard day
Tap where you are and close it. No compulsory questions, no filling in yesterday, no streak to break. If you do want to talk, the questions get shorter, slower, and leave more room.
On an ordinary day
Most days. Two minutes is enough to keep the picture alive — and it's the quiet weeks that later make a change visible. Without them there's nothing to compare against.
On a good day
Yourni asks what's working — not to get it out of the way before hunting for a problem. What's holding you up, what gave you your energy back, who you were with. Understanding what helps is as useful as understanding what hurts.
What Yourni does
Simple on the surface, careful underneath
The feeling picker
A single tap captures the feeling and how strongly you feel it. You can name it in your own words — or not at all.
Conversation
The assistant picks up what you just said and refers to what you both already know.
Mood trends
Nothing to fill in and nothing to rate — Yourni understands how you're doing from the conversation itself.
Journal
A private space to write. Yourni reads your entries quietly but never replies to them — the journal is yours.
Threads & patterns
Yourni notices what returns — in conversations and in the journal. Topics that run across days, and patterns of what repeatedly helps or hurts. It comes back to them at the right moment.
Memory
Yourni keeps the facts it has learned about you, so it doesn't start from zero every time. You can see all of them in Settings and delete any one of them.
Privacy
Everything you say stays with you
Yourni has no accounts. It doesn't know your name, doesn't read your conversations, and keeps no file on you. The only thing it needs to know is how much of the free allowance you've used this month — so the app works the moment you install it, and holds up for everyone.
- Your data lives on your phone. Conversations, journal, feelings and trends — all of it stays with you and nowhere else.
- Nobody reads what you write. Your words are used for one thing only: writing your reply. Nothing is kept along the way, and nobody comes back to them.
- We know only how much you've used. Your install is a random number to us, plus one running total for the month — how much of the allowance it used and how much is left.
- Deleting the app deletes everything. Permanently, with no recovery — which is the design, not an oversight.
- No account, no name. Yourni doesn't ask for an email or a phone number. It doesn't know who you are — and has no way to find out.
- No analytics, no tracking. Not in the app, and not on this site.
- No sharing. Yourni has no social features and no export to networks.
- No trace on codes. Neither we nor whoever issued a code learns who redeemed it.
Everything that stays with you
Your phone holds everything personal: conversation messages and their summaries, journal entries, selected feelings, derived scores and trends, remembered facts, and the name the assistant calls you.
Yourni needs history to pick up where you left off and to compute trends — but your phone is all it needs for that. No copy exists anywhere else.
What happens to what you write
Replies are written by an AI. To pick up where you left off, it receives your message and only what's needed to continue — what you talked about last time, and how you've been lately.
Nothing is kept along the way: no copies, no records, no reading. Once the reply arrives, the conversation exists in exactly one place — on your phone.
And if you ever want nobody at all between you and the AI, you can enter your own key in Settings — your conversations then go direct.
What we store — and why
Three things: a random number for your install, a running total of this month's usage, and how much you have left from a top-up or a redeemed code.
Why: so the app works the moment you install it, we pay for the AI on your behalf — which means we need to know how much. One number per month; no day-by-day history exists, so we don't know when you checked in or about what.
Gone means gone
Deleting the app deletes its entire database. There is no backup, no account, no recovery — deliberately: data of this kind shouldn't exist anywhere you can't erase yourself.
You can also delete piece by piece — Settings → Memory lets you remove any individual remembered fact.
Why Yourni has no accounts
Signing up is an obstacle — and a link to your identity. Both are wrong here. The name you enter in the app stays on your phone; to us, you're a random number.
What we don't have, we can't lose, sell, or hand over.
No measuring, no metrics
There's no analytics or advertising service in the app, and this site sets no cookies. We don't know which days you open the app, how long you stay, or what you tap.
Yourni improves from what you choose to tell us — not from quietly collected data.
Nothing goes out
Yourni has no social features, no sharing, and no export to networks. Nothing you put into it has a way out.
A place for thinking out loud only works when it's genuinely private.
Codes with no link to you
Whoever issued a code — a therapist, an employer, a gift-giver — sees only how many were redeemed: "37 of 50". Not who, not when, not whether you still use the app.
Being able to watch a specific person would break the trust this whole thing rests on. So Yourni doesn't have that ability, even technically.
The app
What Yourni costs
A mental health tracking app that stops working the moment money is tight makes no sense.
Yourni is still in development
It isn't on the public App Store yet. Want to be among the first to try it?
The basics, free
The daily check-in, a short conversation, the journal and the trends — with a monthly limit that covers ordinary use.
Your own key
If you have your own OpenAI or Anthropic key, enter it and the allowance stops applying to you. The key stays on your phone, and your conversations go directly between you and the provider — we're not involved. You pay them directly.
Top up Planned
When the allowance isn't enough, buy more usage in the app. No subscription and no auto-renewal — you pay for what you use, and only when you want to. The price covers the AI costs; Yourni doesn't make money on it.
A provided code Planned
A code with the usage already paid for — from a therapist, an employer's programme, or as a gift. A therapist sees only "37 of 50 redeemed" — not which client used one, nor whether they still use the app. Being able to watch a specific client would cross a boundary in the therapeutic relationship, so Yourni simply doesn't have that ability.
Method
How conversation becomes a picture
On the surface you tap and talk for a few minutes. Underneath, more is going on — and because this is your mental health, it stands on standard clinical instruments, not on hunches.
A tap captures a feeling
Yourni has a map of feeling: every feeling has its place on it by how pleasant it is and how much energy is in it. One tap records both the kind of feeling and its strength — no words needed.
The conversation is read for signals
While you talk, Yourni quietly notes mentions of mood, energy, sleep, thinking, the body and relationships. What holds you up is tracked with the same weight as what pulls you down.
Mentions become information
A passing mention doesn't weigh the same as a repeating pattern — every signal carries a confidence too. Only from that do the trends and scores you see emerge. A reference point, not a verdict.
The signals rest on clinical standards
PHQ-9 and GAD-7 are the standard questionnaires for depression and anxiety — accurate, but nobody fills them in daily. So Yourni assembles their answers from what comes up in conversation on its own.
Safety
When you need help
Yourni is a companion for ordinary days — it isn't therapy, a medical device, or a crisis service. When it's more than an app can hold, you need a person. These numbers work right now, around the clock and free of charge:
112
Emergency line (EU-wide) — immediate help when life or health is at risk.
116 123
Psychological first aid line (Czech Republic) — for adults in distress.
116 111
Safety Line (Czech Republic) — for children and young people.
Outside the Czech Republic, contact your local crisis line.
Yourni is not therapy or a medical device. It does not diagnose, recommend treatment, or replace a psychologist or psychiatrist. The scores it derives are reference points — if one worries you, discuss it with a professional.
AI can make mistakes. Yourni's replies are generated by AI, which can be inaccurate or misread something. Treat what it says as support, not as professional advice.
Not for minors. Tracking your own mental health with the help of AI is not appropriate for users under 18 without clinical oversight.
Questions
Before you start
Do I need my own AI key?
No. Yourni comes with AI access already set up — install it and start. There's nothing to create and nothing to copy across.
If you'd rather have nobody between you and the AI provider, you can enter your own OpenAI or Anthropic key. It stays on your phone, and your conversations then go direct — bypassing us entirely.
Can I choose which AI Yourni uses?
The provider, yes — Settings switches between OpenAI and Anthropic. There's nothing else to choose: Yourni picks the AI best suited to each part of its work on its own.
Do I have to check in every day?
No. Yourni expects gaps and works with them — it knows how long it's been and opens accordingly. The more regular the record, though, the sooner a shift in trend becomes visible.
Will Yourni tell me if I'm getting worse?
Yourni tracks how you're doing over time and shows the change in your trends. It does not diagnose. The point is that you see the shift — before it becomes unmissable.
Can I delete what Yourni remembers about me?
Yes. Settings → Memory lists every remembered fact, and you can delete any of them individually. Deleting the app removes all local data permanently — there is no backup and no account recovery.
What devices does Yourni run on?
Yourni is an iPhone app for now. Android and browser versions are in the works.
What languages does Yourni speak?
English and Czech. You choose the language in the app, and the assistant speaks it from the very first sentence.
Why I'm building this
Yourni didn't start at a whiteboard
It started from my own experience of how easily a decline goes unnoticed — and how obvious, in hindsight, the signals were for weeks beforehand.
I'm interested in healing and growth, not just coping. That's why Yourni asks on the good days too: what holds a person up is worth understanding as much as what pulls them down. An app that only cares about bad days is collecting half the picture.
It's also why it asks so little of you. I build it to make sense on a bad day — because that's when any app is hardest to use, and exactly when it matters most.
Two quiet moments a day. Yourni remembers the rest for you.
No accounts to create, no keys, nothing to configure — install and start. Yourni isn't on the public App Store yet; when it is, you'll find it here.
