## What is FlowLock?

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.

ONE PAYMENT. NO SUBSCRIPTION. EVER.
Buy it once and it's yours. All six states, every sound bed, no recurring charges. No account, no email, no ads, no data collection. Everything lives on your device and works fully offline.

Made for people who just want to sit down and get into it.

FlowLock is designed to support focus and relaxation. It is not a medical device and is not intended to diagnose, treat, or cure any condition. Effects vary from person to person.
