Two rings. One on each hand. Built on 30 years of peer-reviewed neuroscience — and finally designed for the way your brain actually works.

The biggest enemy of deep reading isn't laziness — it's a restless nervous system. Your mind wanders, you reread the same paragraph, you reach for your phone.
Focos gives your hands something to do so your brain can stay on the page. The alternating pulse runs quietly in the background. You stop noticing it. You stop wandering.
The alternating left-right haptic rhythm automatically down-regulates the amygdala — the brain's threat and distraction centre. Less noise. More signal.
As the amygdala quiets, the prefrontal cortex comes online. This is where sustained attention, rational thought, and deep focus live.
Your nervous system shifts from fight-or-flight into calm and focused. The body settles. The mind follows. The work gets done.
One slow cycle every 1.5–2 seconds. For calming anxiety, resetting between tasks, or easing into a session when your mind won't stop.
One cycle per second. The science-validated sweet spot for calm alertness and prefrontal engagement. Your default for reading and deep work.
Two to three cycles per second. Higher activation for creative thinking, active recall, and sustained output when you need to be sharp.
Bilateral stimulation was developed in the late 1980s as the core mechanism of EMDR therapy. Since then, over three decades of neuroscience research has documented what it does to the brain. Focos is the first consumer product to bring this mechanism to daily focus and attention — calibrated at the right intensity, in the right form factor, for the right use case.
Bilateral stimulation reduces amygdala reactivity — the brain's threat and distraction alarm. Less noise from the amygdala means less mind-wandering, less anxiety, and less resistance to staying on task.
As the amygdala quiets, the prefrontal cortex activates. This is the seat of executive function — sustained attention, decision-making, and rational thought. Measured by near-infrared spectroscopy in healthy volunteers.
The nervous system shifts from fight-or-flight into rest-and-focus. EEG studies confirm increased frontal alpha activity and reduced autonomic arousal — regardless of whether stimulation is visual or tactile.
"Bilateral stimulation increases prefrontal cortex activation and reduces amygdala activity — shifting the brain toward higher cognitive processing."

A note on the science: Most bilateral stimulation research was conducted in clinical therapy contexts. Focos does not claim to be a medical device or to clinically treat ADHD or any other condition. What is well-documented is the underlying mechanism — bilateral stimulation calms the nervous system and engages the prefrontal cortex. A calm, focused nervous system is the foundation of sustained attention. That is what Focos is built on.
Focos is built on the CTV03 ceramic ring platform — 5.2g, zirconia ceramic outer, stainless steel inner, 5ATM waterproof. Premium materials, minimal footprint.
Open the case. Put on both rings. Your session begins. Close the case when you're done — the rings charge automatically.
The ritual of opening and closing the case becomes your focus trigger. A physical signal to your brain that it's time to go deep.
Focos isn't only for desk work. Therapists use bilateral stimulation for grounding and anxiety relief. Meditators use it to anchor presence. Athletes use it for pre-performance calm.
Whatever stillness looks like for you — Focos supports it.
