Praenox Aurum for Android
Need to know your next 7 days biometric data?
What it does
Praenox Aurum reads your HRV, deep sleep, REM, and stress, then generates a soundscape built for your body right now — no presets, no static playlists. It runs the same Fusion predictive engine as Praenox Pro, plus mobile-first features: 7-day recovery forecasting, daily context check-ins, and full offline data portability. One-time purchase, lifetime access. Built for people who track their biometrics.
Praenox reads your HRV, sleep architecture, and stress — then generates a therapeutic soundscape engineered for your exact physiological state. Not generic. Not approximate. Yours. The chart now separates the unmanaged baseline, active use across Praenox Free / Pro / Developer, and the Praenox Aurum period. The first marker shows when Praenox started. The gold marker shows the move to Aurum on August 1, 2026. Every data point is entered as-is from the device — including the outliers you can see in the chart. The spike in deep sleep, the near-zero REM night, the recovery dip — all real, all included. If anything, the broken nights make the trend harder to achieve, not easier. The gap in the…from praenox.pages.dev

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
