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 state plays a wordless, evolving piece of music whose volume gently pulses at a set rate, and your attention naturally settles into that rhythm. 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 — 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 with 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.
