Connect WHOOP and Brainwave retunes the melody, tempo and space of every session to today's recovery, HRV and sleep. Endless and wordless, and it never plays the same bar twice.

Short on sleep, heart steady: a gentle lift. A little faster, brighter, more melody.
Pick a morning and press play. The melody, tempo and register follow what your body reports.

Sign in with WHOOP once. Brainwave only reads recovery, HRV, resting heart rate and sleep. It never writes anything back.
When WHOOP scores your night, Brainwave compares it with your own 30-day baseline, not someone else's numbers.
Tempo, mode, melody and register shift to suit the day. A small note always tells you why, and one tap turns it off.
One short night, followed through a day. Every change is small, explained, and yours to skip.
Slept 5 h 40 of the 8 h 10 you needed. HRV and resting heart rate are near your usual, so you're tired, not strained.
96 bpm instead of 84, a brighter Lydian colour and a little more melody. Never fast and loud together.
Brainwave offers five minutes of breathing at six breaths a minute before your next block. Slower, sparser, more space.
Timed to tonight's sleep need. The music slows, sinks lower and fades to silence over twenty minutes.
We tell you what the evidence supports, including where our own idea hasn't been tested yet.
Too little arousal and too much both hurt. That's why a tired morning gets a lift and a strained one gets more space.
Thompson, Schellenberg & Husain 2001; Thompson et al. 2012During practice and right after it, across hundreds of studies. That's why a low-HRV day offers a short breathing break.
Laborde et al. 2022; Goessl et al. 2017That's the open question. We'll measure it in the beta and publish what we find, even if the answer is “not much”.
Brainwave beta, 2027No tracks, no playlists, no seam to notice. Hours in, it still hasn't repeated itself.
Count up, count down, or work in intervals of any length. Sessions end with a slow fade, never an alarm.
We keep today's few numbers and your baseline, nothing more. Disconnect and they're deleted.
Four modes and a dozen styles, from warm lo-fi to deep night drones, plus a breathing pacer.
Planned pricing. Beta members get a founding price when Plus launches.

WHOOP lets a new app connect ten members to start with, so the first round is small. Leave your email and we'll write when there's a spot. We only email about the beta and the launch.
No. Brainwave works on its own. WHOOP adds the daily tuning.
Your recovery score, HRV, resting heart rate and last night's sleep and sleep need. It's read-only: nothing is written to WHOOP, and everything is deleted when you disconnect.
We don't claim that. Brainwave adjusts the music to suit the day, based on research about music, alertness and breathing. Whether that beats a good default is what the beta will measure.
No. Brainwave is calm music for focus, rest and sleep. It doesn't diagnose or treat anything.
No. Brainwave is an independent app that connects to WHOOP through its official developer platform.
