Peace of mind, one tap a day
One tap.
And everyone
stops worrying.
Pruuf sends one message to the people who love you — I’m OK today. And on the morning it doesn’t come, it tells them that too.
Free forever for the person checking in. 15-day free trial for the family.
Live — tap it and see
Her daughter’s phone
Why this exists
The danger was never
the fall itself.
Every family with someone living alone runs the same quiet system. Somebody calls each morning. If there’s no answer they call again. Then they call the neighbour. Then they get in the car.
It works, right up until the morning somebody is in a meeting.
Pruuf started with one woman in her own house, who was fine, and a daughter three states away who called every morning at nine — not because there was anything to say, but because the silence was unbearable.
A daily check-in doesn’t stop anything from happening. It means nobody is alone with it for three days.
Two people, one app
Which one are you?
Pruuf asks this on the very first screen, and then never asks you to think about the other side again.
It asks one thing of you, once a day.
- No account. No password. No username to remember.
- One button, big enough to hit without your glasses.
- A reminder half an hour before your time, so it’s hard to forget.
- Nothing else on the screen to press by mistake.
- It never shows anybody where you are.
- iPhone, iPad and Apple Watch — check in from whichever is nearest, and add as many of your own devices as you own. One account covers all of them.
- As many people as you want. Children, neighbours, the whole family — there is no limit and it does not cost you a penny more, because it never costs you anything.
- Free forever. Not a trial, not a first year. The person checking in is never charged.
You’ll know before you’d have thought to ask.
- A notification the moment they check in.
- An urgent alert if their time passes and they haven’t.
- An urgent alert the second they press I NEED HELP.
- Call or text them straight from the alert.
- “I’ve got this” — so three siblings don’t all ring at once.
- Follow your mother and your father on one subscription.
How it works
Four steps, then never again.
Setting Pruuf up takes about three minutes, once. After that it is a single tap a day, forever.
Choose the time
Pick the time you’ll have tapped by — say 10:00 in the morning. That is the whole of the promise.
Add your people
Pick them out of your contacts. Pruuf writes the invitation text for you and gives you a six-character code.
They type the code
They install Pruuf and enter those six characters. Connected. No accounts on either side, so nothing to lock anyone out.
Tap once a day
Everyone gets told you’re fine. That’s the entire routine, and it takes about a second.
The six characters
There is no password, because there is no account.
This is the single decision that makes Pruuf usable by an 82-year-old. There is nothing to sign up for, nothing to verify, nothing to reset at eleven o’clock at night. A code connects two people, and that is the whole of the security model — which also means there is no password of yours for anybody to steal.
The part that matters
The alert doesn’t
come from her phone.
Almost everything that calls itself a check-in app is a reminder running on the phone of the person being checked on. Which means a dead battery, a phone left charging in the bedroom, or a phone at the bottom of a handbag all look exactly like a phone that simply had nothing to say.
Pruuf’s alerts run on our servers. At her check-in time the server looks for a tap. If there isn’t one, everyone connected to her is told — whether her phone is on, off, flat, or lost down the side of a chair.
The same is true of the help button. Press I NEED HELP and your family is told that second — no countdown, no confirmation step, nothing to reach for afterwards. Somebody who has fallen cannot be asked to confirm anything, so we do not ask.
Pruuf notifies the family members you have added. It is not an emergency service: it does not contact 911, an ambulance, or a monitoring centre. We say so here rather than in a footnote, because it is the kind of thing you should find out now and not later.
iPhone · iPad · Apple Watch
Whichever one is nearest.
Full Apple Watch and iPad apps, not shrunken copies of the phone one — and you can connect as many of your own devices as you like, at no extra cost. Tap from the watch on your wrist without going to find the phone, which on the days it matters most is the difference between checking in and meaning to.
Plainly
What Pruuf
doesn’t do.
A product for frightened families could sell almost anything. This is the list we hold ourselves to.
- No location tracking. Not optional, not buried in a setting — Pruuf never asks for location and could not show it if it wanted to.
- No cameras, microphones or health data.
- No feed, streaks, badges or scores. Missing a day is not a failure to be shamed for. It is a signal to act on.
- No selling of data, and no advertising or analytics trackers of any kind in the app.
- No account to break into, because there are no passwords at all.
- Not an emergency service. It tells the family you added. It does not dispatch help.
Pricing
The person checking in never pays.
Charging an 80-year-old for the button that tells her family she’s alive is not a business we want to be in. Sending is free, for unlimited people, forever. The family who wants the alerts pays, once, for everyone they look after.
For the person checking in
$0
Forever. Not a trial.
- The I’M OK button
- The I NEED HELP button
- Your own reminder before your time
- iPhone, iPad and Apple Watch — as many of your own devices as you want, on one account
- Unlimited people receiving your check-ins — add five children and three neighbours if you like; the price is still nothing
Sending is always free. There is no tier, no cap and no upgrade that changes that — the person whose safety this is never has to pay for it, and never has to ask anybody to.

Questions
The things people ask first.
What if they forget to tap it?
Then their family is told — which is the entire point. Pruuf does not try to work out whether a missed day is forgetfulness or something worse, because from the outside those look identical and only one of them is safe to assume.
In practice, forgetting is rare: a reminder arrives on their own phone 30 minutes before their time, and the routine settles in within about a week. Families usually agree on a check-in time slightly later than the real one, so an ordinary lie-in doesn’t start anything.
Does it show me where they are?
No — and it never will. Pruuf does not ask for location permission and has no location data to show. It answers exactly one question: have they said they’re OK today.
This is deliberate. The moment an app like this becomes a tracker, the person being tracked stops wanting it on their phone, and an app that gets deleted protects nobody.
Is my mother going to be able to use this?
That is the question the whole app is designed around. There is no account, no password and no username. Her screen has one enormous button on it and almost nothing else. The text scales all the way up if she has already turned text size up on her phone.
Setup is the only part that takes a moment, and it is normally done by whoever is reading this, sitting next to her, once.
What happens if her phone is dead or lost?
The alert still fires. Pruuf’s missed-check-in alerts run on our servers rather than on her phone, so a flat battery, a phone in another room, or a phone that has been left in a taxi all produce the same result: her time passes, no tap arrives, and you are told.
Does it work on Apple Watch and iPad?
Yes — both, as proper apps rather than stretched versions of the iPhone one. The watch has its own check-in button and its own complication, so the day’s check-in can be a glance and a tap without going to find a phone at all. The iPad lays out for the bigger screen rather than blowing the phone layout up.
Connect as many of your own devices as you like. One account covers all of them, they stay in step automatically, and alerts arrive on every one — so it does not matter which is nearest when something happens. Adding devices never costs anything, on either side.
Can more than one of us get the alerts?
Yes — as many as she likes, with no limit and no cost to her. Every one of them is alerted. Whoever acts first can press “I’ve got this”, which tells the others to stand down so she doesn’t get four phone calls in ninety seconds.
Only one of you needs to subscribe for her to be covered, and adding more people to her list never changes what anybody pays.
Can I follow both of my parents?
Yes — one subscription covers everyone you look after, however many that is. You’ll see each of them on one screen with the time they checked in.
Is it an emergency alarm? Does it call 911?
No. Pruuf notifies the family members who have been added, and nobody else. It does not contact emergency services, an ambulance service, or a monitoring centre, and we would rather be clear about that than sell you something on a misunderstanding.
If someone needs help right now, call your local emergency number.
What do you store about us?
A first name, a check-in time, which people are connected to which, and the times check-ins happened. That is close to all of it. There are no passwords because there are no accounts, there is no location data, and there are no advertising or analytics trackers in the app.
You can delete your account and everything in it from inside the app at any time. The full policy is written in the same plain language as this page.
I run a care agency. Can I use this for our clients?
Yes — there is a version of Pruuf built for organisations, with a dashboard showing every client’s status, alerts routed to your on-call coordinator as well as to the family, and a timestamped record of who was told and when.
For care providers
Responsible for a hundred people, not one?
Home care agencies, senior living operators and care networks use Pruuf to put eyes on every client every day — without a single extra visit — and to hold a record of exactly who was told and when.
