Feel their heartbeat
on your wrist.
Sevi records your real heartbeat on Apple Watch and sends it to the one person who matters. They feel it — beat for beat — as gentle taps on their wrist.
How it works
Three quiet steps.
1
Record
Hold still for a few seconds. Your watch reads your pulse — your real one, not an emoji.
2
Send
One tap sends it to your partner. No feed, no followers, just the two of you.
3
Feel
Their watch taps out your heartbeat, speeding up and slowing down just as yours did.
What you share
Small things that mean everything.
Touch rhythms
Tap a rhythm on your watch. They feel the same rhythm on theirs — your own private language.
A countdown you both see
Counting down to seeing each other? It lives on both of your watch faces.
A quiet timeline
Every heartbeat and Touch you share becomes part of your story, in one place only the two of you can see.
Private by design
Moments are ephemeral: played recordings clear after 24 hours, unplayed ones after 30 days. No ads, no analytics, ever.
Pricing
One subscription. Both of you.
When one of you subscribes, you both get Sevi Premium.
Try it free for a weekQuestions, answered.
Do we both need an Apple Watch?
You need an Apple Watch to record and feel heartbeats — that's where Sevi lives. The iPhone app handles pairing, your shared timeline, and settings.
Do we both pay?
No. One subscription covers both of you.
Where does our data live?
On Google Cloud (Firebase) servers in Europe. Recordings are shared only with your partner and clear automatically — see the Privacy Policy.
Can we delete everything?
Yes, in the app: Settings → Delete Account permanently removes your account, your personal data, and your shared history — for both of you.
Is Sevi a dating app?
No. Sevi connects exactly two people who already have each other.
