About
We built this for the person who writes things down and deletes them.
Open Heart started with a simple observation: the people who care the most about their relationships are often the ones who struggle the most to speak up. They notice things. They feel things. They write them down in their Notes app at midnight. And then they delete them, because saying it out loud feels too risky.
We built Open Heart for that person. Not a therapy app. Not a quiz game. A private, encrypted space where you write what you're actually feeling, and when you're both ready, you see each other's words at the same time. Nobody goes first. The app is the messenger, not you.
Every decision we've made comes back to one question: does this make it safer to be honest? That's why we chose end-to-end encryption (we can't read your entries, even if we wanted to). That's why solo mode works without a partner. That's why the reveal is simultaneous.
What we believe
Privacy is architecture, not policy
We don't promise not to read your data. We built a system where we physically can't.
Solo is valid
You don't need your partner's permission to work on your relationship. Solo mode is real, free, and permanent.
Safety is not optional
Crisis resources are always one tap away. Detection runs on your device. We never log it.
Structure creates safety
Most check-ins fail because they're unstructured. Bounded categories, contained prompts, and simultaneous reveal change the dynamic.
The team
Open Heart is built by a small team that cares about relationships, privacy, and building software that doesn't exploit the people who use it. We're based in the UK and building for couples everywhere.
