Why HalfHeart
“I’m fine” when you’re not. Going quiet and hoping they notice. Saying sorry and not knowing if they’re still upset. HalfHeart gives the feelings that are hard to say a shape you can both see.
Pull your half away and your partner reads “Sam is upset”, never “Sam is angry at you”. The message lands softly, so it doesn’t start a new argument.
Ask for a little room, or lock your half for a few hours. Your partner knows you need time, and when you’ll be ready, instead of guessing.
A rose from your partner takes hours off a lock, or opens it straight away. Saying sorry becomes a small, sweet gesture.
Blue for missing you, gold for proud of you, silver for a low day that isn’t about you. One look tells you, wherever they are.
Your timeline keeps “Made up after 9 hours”, your anniversaries and your plans. What a fight was about is never recorded.
Pair with one partner using a private code. No ads, no tracking, no feed and nobody else watching.

This is how the heart works in the app. You’re Sam, and Alex is your partner. Drag your half to the left, let go, and watch what Alex sees.

Your timeline
Coming back from a lock adds a moment. The fight itself is never recorded.
Inside the app
No chat to keep up with and no feed to scroll. Just a shared heart, a garden of roses and the story of the two of you.
Colour
Swipe your half up and five candy colours fan out. Slide to one and let go. Your partner sees it straight away, with a gentle nudge on what might help.
Distance
Drag your half away to show how much room you need. The further you pull, the longer it stays apart. Nothing is sent until you let go, and you get 5 seconds to undo.
Locks are fixed: not even you can come back early. Only time, or a rose from your partner, opens them.
Roses & garden
Roses grow in your own moonlit 3D garden. Pick one and send it to your partner, and it takes time off their lock. The garden glows with lanterns and fireflies while your heart is whole, and frosts over while a half is locked.
Timeline
Build a timeline of your relationship together: the day you met, your first date, anniversaries, birthdays, trips and plans. HalfHeart counts your days together and counts down to what’s next.
Sound & touch
When a half comes home, the heart pops back together with a juicy pop, a chime, a burst of hearts and a lub-dub heartbeat you can feel in your hand.
How it works
HalfHeart is for exactly two people. No public profile, no groups, no strangers.
Sign up with Google, or with an email and password. Your partner does the same on their phone.
One of you taps Generate Code and shares the 6 characters. The other enters it. It works once, for 24 hours.
Pull apart, change colours, send roses and build your story together, one half each.
Who it’s for
Feel each other’s mood across time zones, send a rose every day and count down to the next visit.
HalfHeart for long-distance couplesMiss each other during the day? Turn your half blue and they’ll know, without a single message.
If “I’m hurt” or “I need space” is hard to say out loud, let your half of the heart say it for you.
What happens in your heart stays between the two of you. HalfHeart is built to collect only what it needs to work.
