FocusBot synthesizes binaural frequencies, Solfeggio tones and ambient noise in real time on your device — with a Smart Pomodoro timer and a privacy-first Bitcoin license. Nothing is tracked, recorded, or uploaded.
Four tools, one lightweight Chrome extension — everything generated locally with the Web Audio API.
Real-time binaural beats from Delta to Gamma (100–1000 Hz, custom range). Exact left/right pairs with zero audio files — synthesized in your browser.
All ten Solfeggio tones, 174 Hz through 963 Hz, delivered as equal-phase mono carriers — including the famous 432 Hz and 528 Hz frequencies.
Pink, Brown, Rain and White noise layers sit under your tones with independent volume stages. Clearly audible, richly diffused ambient beds.
25-minute focus / 5-minute break cycles that auto-start the frequencies with each focus phase and auto-pause on breaks. A soft 528 Hz crystal chime marks every transition.
€12 Bitcoin payment per 1-year license, direct to the developer. No card, no bank, no billing address — and a full 15-minute frictionless trial before you pay.
Every preference, your trial window and your license state stay in your local browser. No trackers, no analytics, no servers tracking what you do.
Each mode targets a distinct cognitive state through precise frequency patterns.
Every frequency, its cognitive effect, and the tools that keep you in the zone.
No auto-renewal. 365 days full access per payment.
(Payment Note: To maximize user privacy and prevent unauthorized recurring card charges, FocusBot exclusively accepts Bitcoin for 1-year licenses. No credit card details, billing addresses, or personal financial data are ever requested, processed, or stored.)
The full audio engine runs in this page — pick a brainwave, layer ambient noise and run a Pomodoro session. Everything is synthesized locally in your browser.
Binaural beats, the full Solfeggio spectrum, Pink/Brown/Rain/White ambient layers and a Smart Pomodoro timer — free for 15 minutes, then a 12€ / 1-year Bitcoin license.
The interactive widget also sits in the bottom-right corner of this page — click the app icon there to open the full frequency panel, ambient sliders and Pomodoro controls.
Install the extension from the Chrome Web Store or load it unpacked in Developer Mode. Try it free for 15 minutes with no payment details required.
