FlowLock: Focus Music

Music engineered to lock you in. Pick a state, press start, and FlowLock builds a sound field tuned to exactly what your brain needs to do next, then gets out of your way.

Each of the six states plays a wordless, evolving piece of music whose volume pulses at a specific rate, and your brain naturally follows that pulse. It's the same kind of amplitude-modulated music validated in peer-reviewed research for supporting sustained attention. It's not binaural beats, and not a tone hidden under the music. The music itself is the pulse.

SIX STATES, ONE FOR EVERY KIND OF WORK
- Deep Focus: peak concentration for hard problems, coding, writing
- Active: energized alertness for admin, planning, tactical work
- Study: calm absorption for reading, courses, retention
- Create: open, associative flow for design and ideation
- Unwind: decompression and reset when the work is done
- Sleep: a slow descent into delta for sleep onset

BUILT TO DISAPPEAR
- Start a session, lock your phone, drop it in your pocket, and the music keeps playing with lock-screen controls.
- Every session eases in: the pulse glides up to its target rate so you settle, not startle.
- Beautiful, calm, alive. Visuals that move with the music, and hold perfectly still if you use Reduce Motion.
- Lock Quality scores how undisturbed each session was, so you can watch your focus improve week over week.
