A subtle overlay that uses bilateral stimulation to reduce anxiety, sharpen focus, and regulate stress while maintaining your flow.
"I trade during market open and my heart rate used to go insane. With Bilu running in the background, I feel genuinely calmer under pressure. My decisions are sharper because my nervous system isn't in panic mode anymore."
"I use it every day for deep work. My stress is noticeably lower and my focus is sharper. Bilu keeps the ADHD in check and the distractions at bay."
"The breathing guide has genuinely changed how I handle deadline anxiety. It's the only focus tool I've kept using past week one."
Most focus tools ask you to pause. Bilu works while you work — a barely-visible overlay running silently in the background, doing the heavy lifting your nervous system never gets a break from.
A semi-transparent orb appears at the edge of your screen — subtle enough to ignore, present enough to work. It bounces left to right while you write, code, trade, or create.
You don't need to focus on it. The rhythmic left-right motion is processed by your peripheral visual system, triggering the same neurological pathways activated in clinical EMDR therapy.
An optional 528Hz tone pans in sync with the ball — left ear, right ear, back and forth. This dual-channel bilateral effect deepens the calming response.
When stress spikes are detected, the orb shifts to a breathing-guide pulse — expanding and contracting to coach your nervous system back to baseline without stopping work.
Burnout isn't caused by working hard. It's caused by your nervous system never getting a chance to regulate — accumulating stress day after day until the system breaks down.
Bilu acts like a passive coolant running in the background. The bilateral stimulus continuously dampens amygdala reactivity, preventing the cortisol accumulation that leads to exhaustion, emotional depletion, and cognitive decline.
Think of it as the difference between a car that runs hot all day and one with a properly functioning cooling system. Same engine. Very different outcome over time.
Connect a compatible Bluetooth heart rate monitor and Bilu becomes adaptive. When your BPM spikes above your personal baseline, the app responds — slowing the ball, shifting to amber and red, and guiding you through a breathing cycle until you're calm.
Compatible with Polar H10, Polar Verity Sense, and any standard Bluetooth LE heart rate monitor.
Apple Watch integration — coming soon.
You don't need a heart rate monitor to access Bilu's breathing guide. Calm Mode lets you manually trigger the full stress-response system — the ball slows, the glow shifts, and the breathing pulse activates on demand.
Choose 2, 5, or 10 minutes. Bilu guides your nervous system through a regulated breathing cycle, then automatically returns to normal when the session ends.
Most bad decisions don't happen because of bad judgment. They happen in the half-second your nervous system hijacks your thinking. Bilu is built for that exact moment — across every part of life where pressure clouds clarity.
A note on this section: Bilu supports emotional regulation and stress reduction. It does not predict markets, improve odds, or guarantee any financial outcome — and it's not a substitute for professional treatment of ADHD, anxiety, or any clinical condition. What it offers is a steadier nervous system for whatever decision is actually yours to make.
A semi-transparent orb that lives above all your windows, across every desktop and Space on your Mac.
The ball intelligently moves away from your cursor so it never blocks anything you're working on.
A 528Hz tone pans in perfect sync with the ball — left ear to right ear, sub-mixed under your existing audio.
Our custom 80 BPM bilateral ambient track layered beneath the binaural tone for deeper calm.
Connect a Bluetooth heart rate monitor and the app automatically responds to stress spikes in real time.
At elevated stress the orb shifts into a breathing pulse — stays expanded until your heart rate fully stabilizes.
No heart rate monitor? Manually trigger the breathing guide for 2, 5, or 10 minutes from your menu bar.
