OneStep is a small support app for daily check-ins, a safety plan in your own words, and calm tools for difficult moments.
The waitlist opens soon
Coming to iPhone first. The app is in English at launch.

What is OneStep?
In about a minute, note how today feels. Then, if you like, choose one small, manageable thing or a short exercise. What helps can stay close: in your Care Kit, and in a Safety Plan written in your own words.
You choose what to use and when. Nothing needs finishing, and skipping is fine.
About a minute, four short questions. You can change an answer later the same day, and Home shows your day back to you.
Swap a suggestion, make it easier or write your own. A short reset takes one, three or five minutes, one step at a time, and you can stop whenever you like.
Care Kit keeps exercises, resets, steps and notes you saved. Your Safety Plan holds warning signs, what helps and people you can reach, in your own words, ready for a harder moment.
OneStep isn't a diagnosis, therapy or a monitored emergency service. No one watches your answers, and it never contacts anyone for you.
How it works
Most days you only need the first. The others are there for when a day turns.
Choose a place on the path to see its screen.
1 / 4 Every day
See your day plainly, in about a minute.
Four short questions: how you feel, your energy, an optional note and whether you feel safe. Home then shows the day back, with one small step.
Not the Mood Scan: that's a separate, longer reflection of eight questions, for when you have the space.
Continue toCheck-in2 / 4 When it gets harder
Help is one tap away on any main screen.
A round button opens grounding, your safety plan, your trusted contacts and urgent help.
OneStep never contacts anyone for you. If you choose, a trusted contact can see a little.
Continue toSupport3 / 4 When you need a next step
Your own next steps, ready before you need them.
Seven parts written on a calmer day, in your own words. “Use my plan now” takes you through it one step at a time.
Urgent numbers stay within reach.

Something small to do in a heavy moment.
Short, silent exercises and My Reset. Keep what helps in Care Kit, where you can pin and order it.
You can try a short exercise further down this page.

Every day
Four short questions, then Home shows your day back to you, plainly.
Afterwards, Home offers one small step. Swap it, make it easier or write your own. It only changes when you choose.
Sample answers from a demo profile, recorded from a pre-release build (English at launch). Choosing a step plays that part of the recording; this page never asks for or saves your answers.

When it gets harder
A round button sits on every main screen. One tap opens grounding, your safety plan, your people and help lines.

The same round button, a heart held in open hands, always in the same place.
Ground myself, your safety plan, your trusted contacts and urgent help.
OneStep never contacts anyone for you. Calls and messages open in your phone's own apps.
If you choose, someone you trust can also see a short, limited view. How trusted contacts work
The app includes help-line numbers for several countries and says plainly that they have not yet been independently checked.
When you need a next step
You build it one question at a time, from choices or in your own words.
A saved plan
It opens on one immediate next step, with “Use my plan now” beneath it. Choose a part to see it in the sample plan.

If you choose, a trusted contact can see two parts of your plan. How trusted contacts work

Trusted contacts · optional
An optional connection for someone close. You invite them, they decide whether to accept, and they see a short, separate view of only the things you switch on.
In developmentThe phones below are recordings of the real app, verified end to end against a local test copy of the OneStep service. It isn't on a hosted service yet and hasn't been released. Each phone says what it shows.
Not finished yet: a hosted service, invitation links that open from a web address (for now, the code always works), and asking a contact for support, which needs push notifications.
You invite them, from your OneStep account. OneStep makes an eight-character code that works once and expires after 72 hours; making a new one stops the old one. You share it yourself. OneStep sends nothing.
So someone close can see a few plain facts, like whether you've checked in, without you writing them out each day.
With their own OneStep account, they see who invited them and exactly what they'd see, then accept or decline. After that, they look when they choose. A forgotten password can be reset by email.
Only what you switch on, and every switch starts off. Never your notes, Journal, answers, scores, Health data or location.
Either of you can end it at any time: you with End sharing, they with Leave. Their view shows nothing more from its next check with the service. Neither of you can take back what was already seen.
Not monitoring and not an emergency service. No one is alerted when you struggle, and they aren't expected to watch or reply.
Robin · uses OneStepFrom Alex's card in Trusted contacts (typed in: OneStep doesn't read the address book), Robin reads what the role means, switches on what Alex would see and reviews it. Create invitation makes an eight-character code, open for 72 hours. Nothing is sent: Robin shares it, in any app.
Alex · Robin's trusted contactNothing reaches Alex from OneStep. Alex hears about it only if Robin shares the code or link.
Robin · uses OneStepThe invitation stays open until it's used, cancelled or 72 hours pass. Nothing is shared while it waits. Make a new code stops the old one straight away.
Alex · Robin's trusted contactAlex enters the code and signs in with their own account. Only then does Alex see who invited them and exactly what they'd see, and choose Accept or Decline. Either answer is fine.
Robin · uses OneStepRobin can change what Alex sees at any time, and add a short note on how to support them. Alex isn't told; the change shows the next time Alex's view checks.
Alex · Robin's trusted contactA separate support view: dated facts, only for what's switched on, Robin's note in Robin's words, and a button that opens Alex's own Messages app. Robin isn't told when Alex looks.
Robin · uses OneStepEnd sharing, after a confirmation. Robin can invite Alex again later with a new invitation; old codes stay refused.
Alex · Robin's trusted contactAlex's open view notices at its next check with the service, about every two minutes; here that took 1 min 55 s, shown faster with a timer in the frame. Nothing Robin shared stays on Alex's phone. Alex can also end it with Leave.
In developmentEnding has been verified against a local test copy of the service, with made-up accounts: the service stops returning anything to Alex and refuses the old code. It hasn't run on a hosted service yet.

Robin and Alex are made up. The recordings are the real app (version 4042386) on a test phone, connected to a local test copy of the OneStep service on a developer's computer, with made-up accounts deleted afterwards — not a hosted service. One phone played both people, switching accounts between takes. In stage 4, Alex's view comes from a second connection between the same accounts, ended by Robin's account through the same step as End sharing. Nothing on this page sends an invitation or asks for anyone's details.
Everything starts off, and nothing is shared until someone accepts. Try the switches to see what Alex's view would show.
Never shared, with anyone
You can choosePractice only
These switches only change the picture on this page. They're not connected to any app or account, and nothing is saved.
Alex's view would show
Nothing yet. With every switch off, Alex's view has nothing from Robin.
These two parts reach Alex only while Robin's Safety Plan is set to sync to the cloud. Warning signs and the other parts never do.
Illustration with made-up values.
In the app, these switches are under Trusted contacts, for each person. Changing them later isn't announced to the other person. Where this is stored: the privacy note

My Reset
Pick what would help and how long you have. The app then puts together two or three small things, one at a time.
What would help
How long
In the app, this builds
Refocus · 3 min: three steps, about two to three minutes in all
Clear a little space, then pick what is next.
The app picks one thing for each step, rotates them so a reset isn't the same every time, puts first what you said helped, and leaves out kinds of suggestion you chose to leave out. Each step takes its own time, and the app shows the plan's own estimate rather than the length you picked. You can skip a step, or swap it for another.
Leave a reset part-way and Home offers, once, to pick it up again. It never opens by itself.

Exercises are silent and go at your pace.

Care Kit
Care Kit holds what you've found useful, so it's close next time. Pin what matters most and arrange the rest; removing something can be undone.
Start one again with a tap.
With roughly how long each takes, and its steps in order.

Over the weeks
On iPhone you can choose to connect Apple Health for sleep, steps and heart figures. That data stays on the phone.

Make it yours
In Settings → Appearance each theme is shown as a small model of the app. Tapping one only previews it; nothing changes until you choose “Use …”.
A theme changes buttons and highlights, the light in every scene and the support button's symbol. Support, warnings and completed things keep their own colours.
An app appearance preview, recorded from a pre-release build with sample data. Choosing a theme here only changes this preview; it doesn't change anything on your phone. On iPhone, OneStep's home-screen icon changes to match after a short confirmation from iOS, which the Lavender and Ocean recordings show before Home.

Your data
OneStep keeps what you record on your phone first. An account is optional: it copies some of it so you can restore it, and never your Journal, medications or Health figures.
On your phone
Your account · optional
Without an account nothing is copied to one, and OneStep works fully on your phone.
Accounts are only offered in builds where sign-in has been set up.
Choose anything you record to see exactly where it's kept.
History, Journal and Insights show what you logged, day by day, with no score.
Export, in Settings, makes a complete file of your data and a summary you can read.
Reset app data clears this phone. With an account, Delete cloud copy removes what was copied; the sign-in itself stays.
On this website
It is not therapy and doesn't replace professional help. It doesn't diagnose anything, and there is no AI in it. Scores in the app are prompts for reflection, not medical scores. Contact-alert screens are previews: nothing is ever sent.
If you are in immediate danger, call your local emergency number now: 112 in Türkiye and across the EU, 911 in the US and Canada, 999 in the UK.
No. OneStep works on your phone without one. An account is optional: it keeps a copy of some of your information so you can restore it. Your Journal, medications and Apple Health data are never copied to an account.
Yes. What you write is saved on your phone first, so check-ins, your safety plan and the tools work offline. If you use an account, copies are sent when you're back online.
Only if you connect it. OneStep then reads seven signals: heart rate, resting heart rate, heart rate variability, respiratory rate, sleep, steps and active energy. It only reads them, never writes, and the figures stay on your phone.
Yes, if you turn reminders on. You can be reminded of each dose and told when a supply is running low. By default the notification doesn't name the medication. Reminders are scheduled on your phone; nothing is sent from a server.
Yes, if you switch reminders on. You set a check-in time, and can give some weekdays a time of their own; reminders follow that schedule. Quiet hours are respected, and a day you have already checked in is skipped. Reminders are scheduled on your phone, never sent from a server.
Yes. In Support preferences you can leave out things like long text, generic advice or too much positivity, and OneStep stops suggesting them. They stay one tap away in Tools and Care Kit, and Support, your safety plan and urgent help are never affected.
Only someone you invite, once they accept, and only what you switch on: for example when you last checked in, or a short note you write for them. Every switch starts off, and either of you can end it at any time. Both of you need an account. The feature is still in development: it has been verified against a local test copy of the service, not yet a hosted one. Notes, Journal, Mood Scan answers, scores, Health data and where you are are never shared.
No. OneStep doesn't alert anyone, and nothing is pushed to a contact's phone. A trusted contact sees what you've shared only when their view checks with the service, you aren't told when they look, and the alert screens in the app are previews that send nothing. It isn't a monitoring or emergency service.
No. It never sends a message or makes a call on your behalf. Call and message buttons open your phone's own apps with the details filled in, and you decide whether to send.

We aren't collecting email addresses yet. When the waitlist opens, you'll be able to join it here, and this page will say exactly what is stored and for how long.
Screens on this page were recorded from a pre-release build with sample data, and may change before launch. Trusted contacts also uses drawings and the app's example with made-up people, because its connected service isn't running yet.
