Yhuu: What Happens When You Build "Relationship Loyalty Testing" as a Product

I came across a small app called Yhuu recently — built with React 19, Supabase, and the Gemini API — and it's a good case study in a genre I hadn't thought much about: anonymous quiz apps aimed specifically at relationships.
The pitch: an interactive platform to test relationship loyalty through shared quizzes and honest, anonymous responses. Structurally it's the same shape as NGL or other anonymous-messaging apps — a link, a form, a reveal — but the content is pointed at partners instead of strangers, which changes the product's whole risk profile.
A few things stood out from a builder's perspective:
The stack is straightforward. React + Vite + Tailwind on the front end, Supabase for auth/data, Gemini presumably powering some kind of response generation or evaluation layer. Nothing exotic — the interesting part isn't the code, it's the product decisions layered on top of a fairly standard anonymous-Q&A architecture.
Anonymity is doing a lot of work. The same mechanic that makes NGL fun for "guess who sent this" among friends becomes something heavier when it's "is my partner being honest with me." Anonymous honesty and relationship trust are in tension — the app is betting that removing social cost produces more truthful answers, but it could just as easily produce answers optimized to look good rather than be honest, since there's no real verification layer.
The engagement loop matters more than the quiz content. Is this a one-time trust exercise you do together, or something designed to pull you back in to keep "checking" on a partner? That design choice is the difference between a fun bonding tool and something that quietly feeds insecurity — and it's a decision made in the retention mechanics, not the quiz copy.
If you're building anything in this space — anonymous feedback, trust-testing, relationship tech — the technical challenge is trivial. The hard part is the product ethics: what does honesty actually mean when there's no cost to lying, and what does "testing loyalty" do to a relationship regardless of the result?
Curious if anyone else has looked at apps in this space — where do you think the line is between a fun trust-building exercise and something that just manufactures suspicion?

The hardest part of building Yhuu wasn't the code. It was figuring out how to make anonymity feel safe, not creepy. Still learning. yhuu.life — would love your thoughts.

I built an anonymous Q&A app for relationships using React + Supabase — here's how it works

The Problem

People rarely say what they actually mean — especially to someone they know personally.

I wanted a way to ask honest questions without the social pressure of asking face-to-face. So I built Yhuu.

What Yhuu Does

Yhuu lets you send anonymous questions to anyone — a partner, friend, or someone you're getting to know. They answer freely because they don't know it's you. You then see their answers compared to what you expected them to say.

That gap between expected and actual? We call it the Vibe Check — and it's where the real insight lives.

The Stack

Frontend: React + TypeScript
Backend: Supabase (auth, database, edge functions)
Hosting: Vercel
Delivery: WhatsApp, Snapchat & Telegram integration
Encryption: All session records are encrypted end-to-end

The Hardest Parts to Build

1. The Vibe Check UI
Displaying two answers side-by-side (expected vs actual) in a way that felt intuitive took several iterations. The emotional weight of that comparison needed to feel meaningful, not clinical.

2. Anonymous delivery without being creepy
The line between "anonymous and safe" and "anonymous and weird" is thin. A lot of the UX work went into making the recipient feel comfortable answering, not suspicious.

3. Retention
This is still unsolved. The first session is compelling — but how do you bring someone back? Still experimenting.

Would love feedback from developers — especially on the architecture and any edge cases you spot. Happy to answer questions about any part of the build!
