The problem

Relationship apps feel like homework. Yours shouldn't.

Most couples apps are built around obligation — daily surveys, forced prompts, streaks that punish you for living life. They treat your relationship like a productivity problem to be solved. Nuzzle treats it like something alive — because it is.

We both stopped using it

One partner checks in. The other drifts. Nuzzle's engagement balance engine quietly notices asymmetry and nudges the lagging partner — without making it a conversation.

It felt like a therapy app

Clinical prompts, forced deep dives, worksheets. You wanted connection — not couples homework.

I don't trust apps with our data

Your most intimate moments, handed to a company whose business model is selling insights about you.

"What if showing up for each other felt like feeding a pet you both love?"

How it works

Small moments.
Big evolution.

No hour-long sessions. No mandatory dates. Just tiny, consistent acts of love that add up to something extraordinary.

Features

Everything your relationship actually needs.

Six features. Each one grounded in relationship science. None of them feel like a chore.

Your creature

Meet the heart of your relationship.

One creature. Shared between you both. It reflects your relationship's emotional state — brightening with connection, stilling with distance — without ever using clinical labels.

You don't choose an archetype. You don't customise a character. The wisp is yours, together.

The wisp reads the room

Its mood and weather state reflect what's happening between you — without either of you having to say it out loud.

Excited

When you're both showing up

Daily check-ins from both partners, a streak running, pebbles sent — the wisp is vibrant and glowing warm.

🌩️ Storm

When things get hard

Tension, withdrawal, or a stretch of silence — the wisp enters the storm state. A shared signal, not a blame. The weather belongs to both of you.

🌤️ Recovering

When you return

The storm clears as you re-engage. The wisp brightens gradually — a visible record that repair happened, and that it worked.

It grows with your relationship

Each stage is driven by relationship age — not points, not tasks. Just time, tended well.

🥚

Egg

Day 1 — the beginning

🌱

Hatchling

Week 1 — first habits forming

🌸

Baby

Month 1 — your rhythm is settling

🌺

Adolescent

3 months — through the hard moments

Legendary

2+ years — a relationship that has weathered everything

Your creature never dies. It waits.

Your creature never "dies."

If life gets hard — long work weeks, grief, distance — your creature enters a contemplative state. It rests, not fades. And when you return, it comes back stronger than before.

The science

Backed by 40 years of relationship research.

We didn't invent relationship science. We just made it feel like a joy instead of a lecture. Every feature in Nuzzle is rooted in peer-reviewed research.

Privacy first

Your relationship is yours.

We built Nuzzle the way we wished other apps had been built. Privacy isn't a policy bullet point — it's baked into the architecture from the ground up.

📱

Your device is the source of truth.

Nuzzle is offline-first. Your relationship data lives in an on-device database (Isar) and works fully without a connection. The app never blocks on network availability.

👁️

We never read your content.

Sync uses encrypted CRDT changesets — structural deltas, not readable content. Even if someone subpoenaed us, there would be no relationship journals, messages, or conflict notes to hand over.

🔐

Encrypted sync, no Nuzzle servers.

When partners sync, data travels through Firebase (Google infrastructure) as encrypted changesets — not through any server we own or operate. Nuzzle has no proprietary backend.

🚫

Zero data harvesting.

No analytics on your conversations. No training AI on your relationship. No selling anonymised insights to advertisers. None. Ever.

FAQ

Questions answered.

Everything you want to know before you commit to your creature.

Do both partners need to download the app?

Yes — Nuzzle is built for two. Both partners download the app, and one person creates the shared creature. You'll get a QR code (or a simple invite link) to connect your partner's account. Setup takes about 3 minutes. Both of you are covered under the single $29.99/year subscription.

What if my partner isn't interested?

Start with the Free tier. Your creature will still respond to your solo check-ins, and many partners come around once they see the creature evolving — especially when you share your screen. There's no pressure, no streak punishment, and no notification spam sent to your partner without consent.

Does it work for long-distance couples?

Absolutely — Nuzzle was partly designed with long-distance in mind. The Simultaneous Touch feature lets both partners press their screens at the same moment for a shared pulse. Mood check-ins, appreciation pebbles, and conversation cards all work asynchronously across time zones. The creature bridges distance beautifully.

What happens to my data if I cancel?

Nothing changes. Your relationship data is stored on your device (Nuzzle is offline-first) and synced via Firebase — not on any server Nuzzle owns. When you cancel Premium, you lose access to cosmetics and seasonal features but everything else stays intact. Your on-device data persists unless you uninstall the app.

Is there a free trial for Premium?

The Free plan is effectively your unlimited trial — there's no time limit, and it includes the core features. If you want to try Premium before committing, watch for our seasonal trial offers. We occasionally run 2-week full-access windows, especially around Valentine's Day and anniversaries.

What devices does it support?

Nuzzle is a Flutter app available on iOS (iPhone, requires iOS 15+) and Android (requires Android 10+). Both partners can use different platforms — iOS and Android work together seamlessly. A web companion for sending pebbles and viewing your creature from a browser is on our roadmap.

Do you use the Gottman Institute's official content?

Nuzzle is independently developed and is not affiliated with or endorsed by The Gottman Institute. Our features are inspired by and grounded in the publicly available research of Dr. John and Dr. Julie Gottman, which spans 40+ years of peer-reviewed studies. We read the papers, built interpretations of the principles, and wrapped them in game design that actually gets used.
