## What is HeartSync?

Keep a love diary with your partner. You each write three short heartbeats, and your check-in stays private until you both finish. Your partner has a reason to come back and write theirs.

Each day or week, you both answer three short prompts, called heartbeats: something sweet your partner did, a moment that made you smile, and a reason you're grateful. You write yours, they write theirs, and neither of you can read the other's until you've both finished. Then the check-in opens for both of you at once.

That's the whole idea: nothing opens until both of you write.

WRITE APART, OPEN TOGETHER
Your couple jornal doesn't need polished words. Write what you meant, then read your partner's side when you've both finished.

THREE GOOD THINGS, FOR TWO
Writing down three good things is a well-known gratitude practice. You each write your own three; after you both finish, they become part of your shared journal.

YOUR MOMENTS, KEPT
Every check-in you both finish becomes a moment in Memories, photos included. Search your moments, or pick a date on the calendar to find one.

A RUN YOU BUILD TOGETHER
HeartSync counts the check-ins you finish back to back. Miss one and the run starts over, and the app keeps your best run without nagging you about it.

MILESTONES
Anniversaries, trips, the day you moved in. Count down to the next one or count the days since.

YOUR RHYTHM
Write daily or weekly, at a reminder time that suits you. You'll get a nudge when your partner has written.

ALSO IN HEARTSYNC
Whispers: send a doodle, a photo or a single line to a widget on your partner's Home Screen. You choose how long it stays.
Love notes: write something now and have it arrive later, at a time you set or as a surprise.

JUST THE TWO OF YOU
You and your partner keep this relationship journal together. Link with a private invite code; what you write stays hidden from each other until you've both finished the check-in.

FREE AND PREMIUM
Free: the full journal, Memories, your run, reminders, Whispers, love notes, up to 3 milestones, and photos on your first 3 check-ins.
Premium: photos on every check-in (up to 5 each), unlimited milestones, the milestone Home Screen widget, Whisper history, and no ads.

Premium is a monthly auto-renewing subscription charged to your Apple Account. It renews unless you cancel at least 24 hours before the end of the current period. Manage or cancel it in your App Store account settings.

## Version history (last 5 releases)

### 1.0.38 — 2026-10-03

Premium can now cover both of you. Pick Just me or Both of us, monthly or yearly: one Both of us subscription unlocks Premium for you and your linked partner, whichever phone they use. Yearly plans start with 3 days free. Already subscribed? Nothing changes - your plan and price stay as they are.

### 1.0.36 — 2026-09-30

HeartSync has a new app icon. We refreshed the look of the icon and startup screen while keeping your check-ins and shared moments as they are.

### 1.0.35 — 2026-09-26

If HeartSync's notifications are turned off, the app now says so and takes you straight to the setting, so you don't miss the moment your partner writes. New installs explain what notifications are for before asking. Scanning your partner's invite QR code is also more reliable.

### 1.0.34 — 2026-09-23

Finishing a check-in now tells you so, with a small chime and a note on whether your partner is done too.

Whispers now keep a history. Every Whisper you two send is saved for a year, and Premium lets you look back at them long after they leave the home screen.

Colours are more consistent in light and dark mode.

### 1.0.33 — 2026-09-22

Reminders and partner alerts were never arriving on some phones. If yours had
gone quiet, HeartSync now keeps trying to register your device instead of
giving up after one attempt at launch.

Opening HeartSync is quicker: the heart now finishes as soon as the app is
ready rather than always running the same length, and the logo no longer
appears twice on the way in.
