Pulse on Apple Watch
The couples app for Apple Watch.
Your Watch already notices the night you had. Pulse turns that into one gentle sentence for the person you love, and leaves every number on the wrist that measured it.
Free · iPhone and Apple Watch · Raw measurements never leave your phone
01 · On the wrist
Small enough to answer between two things.
The whole point of the Watch app is that it is not the phone app. Each view does one thing, in one tap, and then gets out of the way.
-
Today
How their day is going, in a sentence you can act on.
-
Mood check-in
Three taps, and only the level crosses over.
-
Thinking of you
One tap. They feel it, wherever they are.
-
Morning summary
What they answered last night, waiting when you wake.
02 · The whole app
Eight small views, and one gesture.
Four of them are pictured above. Here is the rest of what is on your wrist.
-
Today
Their cue for the day, and the one sentence behind it.
-
Us
How long you have been counting from, and what is coming up.
-
Chat
Read the last messages and answer by dictation or scribble.
-
Mood check-in
Say how you are in three taps. The reason never leaves you.
-
Our Story
The memory from this day in another year, answerable with one tap.
-
Morning summary
Last night's answers, and how the two of you are starting.
-
Ask for what you need
A hug, a talk, some closeness. Chosen, never typed.
-
Reconnect
A way back after a rough evening, without opening with an apology.
The gesture is “thinking of you”: press once, and a wordless signal reaches them with no notification text to read and nothing for anyone standing nearby to see.
03 · How it works
From a signal on your Apple Watch to a sentence your partner can use.
-
01
The Watch measures
Sleep, resting heart rate, heart rate variability and movement, the same readings it already collects for you. Pulse adds no sensors and asks for nothing extra.
-
02
The iPhone interprets, on the device
Your phone compares today against your own recent weeks. Not against anyone else, not against a population, and not on a server. There is no model anywhere in this and no account to send the readings to.
-
03
One sentence crosses over
Your partner gets “a calm evening might mean a lot today”, on their own wrist. Never a chart, never a score, and never a number they could misread at a glance.
04 · What stays
The numbers stay on the wrist that measured them.
This is the part that separates Pulse from a shared fitness dashboard, so it is worth being exact about.
Your readings never reach us
Heart rate, HRV, sleep and steps are read from Apple Health on your own phone and interpreted there. They are not uploaded, not backed up by us, and not part of your account.
Your partner never sees a figure
There is no screen anywhere in Pulse that shows them your numbers, because we did not build one. What they receive is a sentence written for them.
One tap stops it
Pause sharing from the phone at any moment, optionally without telling them, and nothing new crosses until you start it again.

An Apple Watch is what the cues are read from, so a couple where one partner has no Watch still gets the shared space, the chat and the daily question, with no cue from that side.
06 · Questions
Before you pair it.
- Do both partners need an Apple Watch?
- No. The partner wearing one sends cues; the partner without one still receives them, and everything else in Pulse works the same for both of you. Both of you do need an iPhone, because the on-device interpretation and the encryption are built on Apple Health and the iCloud Keychain.
- Which Apple Watch models work?
- Series 6 and later, including SE and Ultra, running watchOS 10 or later. That is the line where the sensor data Pulse reads is available consistently enough to compare a day against your own baseline.
- Will it drain my battery?
- Pulse does not run sensors of its own. It reads what your Watch has already written into Apple Health, and the Watch app is awake only while you are looking at it, so the cost is close to any other small watch app.
- Can my partner see my heart rate on their watch?
- No, and there is no setting that would let them. The only thing that reaches their Watch is one sentence. We wrote an essay about why, because it is the most common feature request we get and the answer is always the same.
It is already on your wrist.
Pulse is free on the App Store. Install it on your iPhone and the Watch app comes with it.
