Get in the zone. Stay there.Timed sessions with audio that adapts as you work.
Focus is the daytime mode in the NextSense app. Pick how long you've got. Put the buds in. The audio does the rest.
Adaptive audio
Soundscapes that shift in real time as you work.
Three session types
Timer, Blocks, or Smart — built around your schedule.
Distraction Blocker
Attention-stealing apps locked out for the session.
Session readout
Where your attention went, block by block.
Three ways to run a session.
Same engine underneath — Smartbuds sense brain activity through the ear and the audio responds while you work. What changes is how the time is carved up.
Timer
A simple countdown for a set length. No structure, just protected time.
Blocks
You choose the work time, the break time, and the number of rounds.
Smart
Tell it how long you have, or when you need to finish. It builds the blocks.
Audio that adapts as you work.
Most focus apps play the same playlist whether you're locked in or three tabs deep in something else. Smartbuds sense brain activity in real time, so the soundscape can change with you — steady when you're deep in the task, shifting to pull you back when your attention drifts.
Pick a track designed to keep you alert and attentive, or bring your own audio from any third-party app.
Block the noise. Settle in.
Switch it on and the apps that usually pull you away are locked out for the length of the session. Smartbuds notice when you drift, and block what pulls you away.
The afternoon slump, met.
Focus doesn't ask you to start a new habit. It makes you better at the work you were already going to do.
See where your attention actually went.
A block-by-block view of focused versus distracted time, your most dialed-in stretch, and your streak as sessions add up.
Illustrative summary. Your readout is built from your own session.
Focused versus distracted time across a session.
Nothing here is a grade. It's a record — so you can see which hours and which soundscapes actually work for you.
Find out when your alertness peaks. Schedule around it.
Your attention isn't flat across the day, and it isn't the same on four hours of sleep as it is on eight. Based on how you slept, My Day maps your natural highs and lows and marks the good windows to Focus, Nap, Meditate, or Sleep — with the option to drop any of them onto your calendar.
Illustrative. My Day anticipates when you tend to focus best based on your sleep — it doesn't predict your day for you.
Why the ear is the right place to sense the brain.
For decades, measuring brain activity meant a lab: roughly 20 wet electrodes glued to a scalp and hours of setup. Headbands and forehead patches tried to close that gap and mostly traded away signal quality for form factor.
The ear canal is a stable pocket inches from the brain with no hair to push through — and somewhere people already wear something for hours a day. Smartbuds sense and play at the same time, so the sound can respond to what it's reading.
NextSense ear-EEG captured 86.4% of focal seizures detected by traditional clinical methods — with a false alarm rate of just 0.1 per day.
