Hey Product Hunt 👋
I built Praenox because I couldn't find anything that actually responded to how my body felt each night — not how it felt on average.
Most sleep audio is static. Same thing every night. But your HRV on a high-stress Tuesday is not the same as your HRV after a recovery weekend. So why is the audio identical?
I spent 8 months testing this on my own data — every night, real numbers from my Zepp, no cherry-picking. The results are on the site: +26% deep sleep, +21% REM, +111% sleep duration vs my 2022 baseline.
The free version is live now for Windows. No account, no subscription. You enter 6 numbers from your wearable app and it generates a session tuned to that exact night.
Happy to answer anything — how the protocols work, how the audio engine synthesizes the session, why I built Pro the way I did. Ask me anything.
