About this app

Every month, millions of couples have the same conversation:

"What's wrong?"
"Nothing."
"You seem upset."
"I'M FINE."

She's not being difficult. She's exhausted from explaining something her body does automatically. He's not clueless - he just has no framework.

Herlune replaces that loop with a shared language you build together.

SIGNALS
One-tap emotional states she sends when she wants to. Not when the app decides. Not on a schedule. When she chooses.

Cocoon - I need quiet, warmth, your presence - not your words
Static - I'm irritated but it's not about you - give me space
Drift - I feel disconnected - pull me closer
Open - I'm great - plan something, I'm up for anything
Spark - I want closeness and intimacy
Fog - I'm low energy, don't expect much from me today
Soft - I'm emotional and sensitive - be gentle
Locked In - I'm focused and productive - cheer me on later

Rename them. Redefine them. Add your own. Remove the ones you don't use. Your vocabulary, your rules.

RITUALS
The agreed-upon response to each Signal. Not a tip from an AI - an agreement between two people.

She describes what helps. He describes what he can realistically do. The middle ground becomes the Ritual. When a Signal arrives, he already knows exactly what to do. No guessing. No tiptoeing.

Rate each Ritual after it happens. Over time, your playbook evolves based on what actually works - not what sounded good in theory.

RHYTHM
Your relationship's feedback loop. At the end of each cycle, both of you independently rate how supported and connected you felt. When both reviews are in, AI writes a short, warm narrative about your week together.

No charts. No clinical data. No grades. Just an honest mirror that shows where you're growing and where you might need to show up differently.

CYCLE INTELLIGENCE (BEHIND THE SCENES)
Herlune is powered by cycle awareness - but it stays invisible. She tracks her cycle privately. The app uses that data to suggest Signals at the right time. He never sees cycle data, phase labels, or symptoms. Ever.

All he sees are Signals, Rituals, and your shared Rhythm score. Her body, her data, her choice.

AI COACH
A private chat that understands your couple's vocabulary. When he's not sure how to respond to a Signal, the Coach helps - using context from your shared language, not generic advice.

WHY HERLUNE?

Your language, your rules. Every Signal, Ritual, and Rhythm is co-created. Nothing is imposed. You build the system that works for you.

Privacy by design. He never sees her health data. She controls what he knows and when. Zero data sharing with third parties.

AI that stays backstage. It suggests, it writes narratives, it coaches - but it never acts on her behalf. She always has the final tap.

No ads. No social feed. No strangers. Just the two of you building something real.

Herlune is free to download. Built for couples who want to stop explaining and start connecting.

Never have to explain yourself again.
