A love diary you keep with your partner, where nothing opens until you both write. Most journals get abandoned because nobody is waiting on them. In HeartSync, your partner is. 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. 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 both finish back to back. Miss one and the run starts over, and your best run is kept. When a run is on the line, your reminder says so, and if you still haven't written, a last call can follow before the day or week is out. Change the reminder time, or turn reminders off, in Settings. 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 also hear 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. Letters: write one now, send it, or seal it to open on a day you choose. Voice clips: add a short recording to your check-in. Look backs: a month or a year of your check-ins, together. App lock: keep your journal behind Face ID or your passcode. Make it yours with colour themes, writing fonts and journal covers. 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, letters, app lock, up to 3 milestones, and photos on your first 3 check-ins. Premium: photos on every check-in (up to 5 each), voice clips, unlimited milestones, the milestone Home Screen widget, Whisper history, the full look back, extra themes, fonts and covers, and no ads.
