Vityss: Sleep, Stress & HRV
The health brain your Apple Watch never had
Your Apple Watch and iPhone collect thousands of data points every night. Most apps just show you a number. Vityss turns it into a Daily Brief — readiness, strain, sleep stages, HRV trends, and snoring analysis — without you having to do anything.
Hey Product Hunt! 👋
I built Vityss because I was frustrated - I had an Apple Watch, years of health data, and no app that actually told me why I felt the way I felt.
Most health apps either drown you in charts or oversimplify everything into a single score. Neither one actually changes your behaviour. So I started building something different.
The core idea: your Watch and iPhone already know everything — the app's job is just to connect the dots. Vityss reads Apple Health passively, runs everything on-device, and surfaces a Daily Brief every morning that actually explains last night. Not just a sleep score - but why your HRV dropped, whether that late coffee showed up in your deep sleep, and whether the sound at 2am was snoring or your AC.
A few things I'm genuinely proud of:
- No backend. No account. No data leaves your phone. This was a hard constraint I set from day one and never broke. Every score, every insight, every snore clip stays on your device.
- The correlation engine. It only shows you links that clear proper stats gates from your own data. No population averages, no invented patterns.
- Passive-first. You don't have to log anything for it to be useful. The optional tracking layer (alcohol, caffeine, mood, meds) feeds the engine - but it never blocks the passive features.
I've been building this solo for over a year. Pro is what keeps it independent - no investors, no ads, no data deals.
Happy to answer anything - architecture, how the snore detection works, why I made certain design calls, anything. And if something feels off or missing, I genuinely want to hear it. 🙏
