Built for the quiet moments that matter most.

Not another tracker. A gentle thread between you and the people you love.

A ritual, not a chore

A 2-second daily tap that becomes the most reassuring habit you've ever built.

Silent alerts

Miss a check-in and your trusted circle is notified. No drama. No false alarms.

Your circle, your rules

Roommates, parents, partners, hiking friends — choose who knows what, and when.

Private by design

End-to-end encrypted location pings. Shared only when you miss a check-in.

Instant SOS

One long-press triggers an emergency alert with live location to everyone in your circle.

Works anywhere

From your daily commute to a solo hike in Patagonia — works on any network, any device.

How it works

Calmer than a text. Smarter than a tracker.

01

Build your circle

Invite the 3–10 people who'd want to know you got home safe.

02

Pick your ritual

Once a day, twice a day, or after late shifts. You set the rhythm.

03

Tap. Breathe. Done.

A two-second hold. Your circle sees a soft green heart appear next to your name.

04

If you go silent…

We wait, we nudge, we follow up. Then your circle is alerted with your last known location.

A pocket-sized promise.

Designed for one-thumb use. Optimized for the 4 a.m. moments. Built so your grandmother can use it as easily as your teenager.

  • Native-feeling iOS & Android experience
  • Works offline — syncs the moment you reconnect
  • Custom check-in tones for each circle

Questions, answered.

Is my location always shared?+

No. Location is only shared with your circle if you miss a check-in. Otherwise, the app shows nothing more than a green heart next to your name.

What happens when I miss a check-in?+

You get a gentle reminder push first. Then a second nudge after 30 minutes. If still no response, your circle is alerted with the time of your last check-in and your last known city.

Can I use it for elderly parents?+

Absolutely. Family plans were built for exactly this — a single shared dashboard with very large, simple buttons for less tech-savvy users.

How is this different from Life360 or Find My?+

Those apps share location continuously. Proof of Life flips the model — silence is the signal. Privacy is the default; alerts are the exception.

Does it work without internet?+

Yes. Check-ins are queued offline and sync the moment you reconnect, so a weak signal never triggers a false alarm.

The smallest habit. The biggest reassurance.
