RULIO ENGINE
Brussels · 2026
Rulio Engine is an adaptive audio app that builds 5–60 minute sessions from the 1,000-year-old solfeggio scale — combined with binaural beats, solfeggio harmonics, and an AI coach. For founders who need focus, calm, and creative flow on demand.
No credit card. No app install. 30 minutes, free.
396 Hz at 4 Hz offset. The frequency for hard days. Headphones on, one breath, 5 minutes, go.
417 Hz + 852 Hz, layered. The frequency for shipping. 5 minutes before the Pomodoro, then 50 minutes of focus.
528 Hz at 8 Hz offset. The second-wind frequency. 20 minutes, eyes closed, then walk.
852 Hz at 14 Hz offset. The frequency for looking back. 5 minutes, then 5 minutes of journaling.
174 Hz + 528 Hz, layered. The sleep-start combination. 10 minutes, lights out, the frequencies do the rest.
Build your own from any combination of the 9 frequencies. Save as a preset. Share with a signed URL.
A structured look at your current state — energy, focus, creative flow — and a 5-minute session built from the frequency that matches the next 14 days of your schedule. No pitch, no upsell.
