For independent adults & the people they trust

She doesn't have to bother you. You don't have to monitor her. You just know.

When Mom's on a long call with a number that isn't in her contacts, you get a calm heads-up. No recordings. No tracking. No hovering.

The moment we're built for

She doesn't want to bother you.
You'd rather be bothered.

What Mom thinks, mid-call

"I don't want to bother her."

"She's working."

"It's probably nothing."

What you think, three days later

"I wish I had known."

With Just Know, she doesn't have to decide in the moment whether something is important enough to bother you. If a call with an unknown number runs long, you just know.

How it works

Small signal. Big difference.

  1. She picks her person.

    Mom installs Just Know and texts you an invite herself. You join, then she approves you. Nothing's shared until she does.

  2. An unfamiliar number calls.

    Only numbers that aren't in her contacts count. Calls from people she knows never ping you.

  3. If it runs long, you get a heads-up.

    Most unknown calls are over in a few minutes, so nothing happens. At 7 minutes, you get one calm alert. If it keeps going, a text, then a call.

  4. You decide what it means.

    "I know about this." "Call Mom." Or "Trust this number" so the pharmacy never pings you again.

Call starts nothing yet 7 min calm alert 11 min a text 15 min we call you 1 hr later "Did you figure it out?"

Straight answers

You don't need to know everything.
Just when something's different.

You'll see

  • That Mom's been on a long call with a number not in her contacts
  • How long it's been going
  • The last 4 digits — if she chooses to share them
  • Whether it wrapped up okay

You'll never see

  • What anyone says on the call
  • Her text messages
  • Where she is
  • Which apps she uses
  • Her bank, cards, or accounts

Made for both of you

For her

Stay independent. Still keep your people close.

  • It's her app, on her phone. She picks her people and can remove anyone, anytime.
  • She sees everything her people see. No secret views.
  • One big button when a call feels off: "Did they contact you first?"
  • No scam lectures. No scary dashboards.
For you

Stop checking in. Start knowing.

  • Calm alerts — never "URGENT FRAUD DETECTED!!!"
  • Action Hours: follow-ups land before the bank closes, when fixing things is still easy.
  • In a meeting? Hand it off to your brother. One person on it, not five.
  • Busy in the moment? Just Know asks later: "Did you figure it out?"

We'd rather tell you than fake it.

On Android, Just Know can notice unknown calls automatically — using the same official "caller ID & spam" permission spam blockers use. Apple doesn't let any app see calls on an iPhone, so iPhone users get the "Did they contact you first?" button and a home-screen shortcut instead. The person getting alerts can use any phone.

Questions

The stuff people ask first.

Does Just Know record or listen to calls?

No. Never. It doesn't record, listen, transcribe, or read anything. It only notices that a call with an unfamiliar number started, and how long it's been going.

Is this spyware for parents?

The opposite. The person with the phone installs it, chooses who's in her circle, sees everything they see, and can remove anyone or pause it anytime. Nobody can add themselves.

Does an unknown number mean it's a scam?

No — and we'll never say it is. The doctor's office calls from unknown numbers too. Just Know tells you something's different. You decide what it means. Tap "Trust this number" and it won't ping you again.

What if I miss the alert?

Nothing buzzes until a call has gone 7 minutes. Then you get an alert. If it keeps going, Just Know texts you at 11 minutes and calls you around 15. After the call, it asks "Did you figure it out?" — timed to land before banks close.

What does it cost?

Pricing isn't set yet. We'll share it well ahead of time, and nobody is ever charged without saying yes first.

Can more than one person be the "Trusted Person"?

Yes. One person is "on point" at a time so the whole family isn't piling on — and they can hand it off with one tap.

Why we built this

"I've spent 14 years inside thousands of homes. The families who got blindsided almost never lacked love or warnings. They lacked a heads-up in the moment. So I built one."
Jessica DeCandia, founder — Fort Worth, Texas
