Understanding each other,
gently.

Pulse turns the quiet signals from your Apple Watch into small, human cues for your partner, never numbers, never a verdict. The raw data never leaves your phone.

Designed in Vienna On-device processing No advertising
The promise
Help partners understand each other without needing to explain everything.
The principle Pulse is built on.
01 · How it works

Four quiet steps,
nothing personal leaves your phone.

01

Watch listens

Sleep, resting heart rate, HRV, movement, recovery, the same signals your Apple Watch already records.

02 14-DAY BASELINE TODAY

Phone interprets

Your iPhone compares today against your own rolling baseline, locally, never in the cloud.

03 Sleep hints Activity cues Recovery signals

You decide

Toggle what you want to share, sleep hints, activity, recovery. Pause or hide it at any moment.

04 A calm evening might mean a lot today. A

Partner receives a cue

A short, human sentence, “A calm evening might mean a lot today.” No numbers. No medical claims.

02 · The surface

One screen.
The whole day.

The home screen shows your day, a cue from your partner, a few gentle suggestions and a quiet count of the days you've been there for each other, written like a thoughtful friend would, not like a chart.

  • Daily, then gone

    Cues expire at midnight. No history archive your partner can scroll through.

  • Suggestion, not surveillance

    Each cue comes with a couple of small things to do, a message, an offer of space, a quiet evening.

  • One pause button

    Stop sharing for an hour, a day, or forever, with one tap. Optionally invisible to your partner.

A small surface for the smallest gestures.

04 · Principles

The rules we won’t break.

01

Raw health data stays on your device.

Heart rate, HRV, sleep duration, step count, your partner never sees the numbers, and neither do we. Processing happens locally on your iPhone.

02

Cycle data is never shared. Ever.

If you enable Rhythm Awareness, your cycle quietly informs the tone of cues, but the phase itself is never sent, displayed, or stored in the cloud.

03

No certainty. Only “might”, “may”, “could”.

Wellness signals are not diagnoses. Every message Pulse writes leaves space, for context you know and we don’t.

04

One pause button, always.

Stop sharing instantly, optionally without your partner being notified. End the connection and every shared record is removed.

05

No advertising. No third parties.

Pulse is paid for by the people who use it. Your wellness, your relationship, and your patterns are not products.

a short note

Hi. We made this for two people we love.

One of us kept asking the other, "are you okay?". The honest answer was usually yes, mostly, but on the days it wasn't, neither of us knew how to start. Pulse is the small bridge we wanted then.

It is intentionally small. It does not predict your mood. It does not pretend to know you. It just hands you a soft word on the days a soft word might help.

If it does that for you and the person you love, we have done our job.
