Pick a state, press start, and FlowLock eases you into the flow state for the work in front of you. A wordless sound field pulses at exactly the rate your brain needs, then gets out of your way.
Each one is built to drop you into the flow state that fits the task, with its own evolving piece of music tuned to a specific brainwave range. You just choose where you're going.
Peak concentration for hard problems, coding, writing, solo execution.
Energized alertness for admin sprints, planning, tactical problem-solving.
Calm absorption for reading, courses, notes, retention work.
Open, associative flow for design and ideation.
Decompression and reset when the work is done.
A slow descent into delta for sleep onset.
No tones buried under a track. No binaural trickery. The volume of real, composed music rises and falls at your target rate, and your brain naturally follows.
Six states, from 40 Hz deep focus down to 2.5 Hz sleep. Tap one and set your length, from 10 to 90 minutes.
Every session glides the pulse up to its target rate, so you settle into the state instead of getting startled into it.
Drop it in your pocket and stay in the flow state. The music keeps playing with lock-screen controls, and Lock Quality scores how undisturbed each session was.
FlowLock is built on amplitude modulation, the same class of mechanism validated in peer-reviewed research for supporting sustained attention. It is not binaural beats, and not a tone hidden under the music. The music you hear is the thing your brain locks onto.
Visuals that move with the music, and hold perfectly still if you use Reduce Motion.
Everyone else rents you focus by the month. FlowLock is yours the day you buy it.
No. Binaural beats play two slightly different tones, one in each ear. FlowLock is different: the actual volume of composed music rises and falls at your target rate. The music is the pulse, so it works on speakers too, though headphones feel best.
Headphones give the richest experience, but because the pulse lives in the music itself, FlowLock also works fine through your phone speaker or any Bluetooth speaker.
