LockIn: Focus & Sleep Music

LockIn is focus music and real nature sounds for deep work, study and sleep. Sign in with your LockIn membership and press play.

Pick a state (Focus, Relax, Meditate or Sleep) and LockIn weaves a steady neural pulse into real studio music. The pulse is set for the state you chose, so the same press of play can carry you into deep focus in the morning and toward sleep at night.

FOCUS MUSIC FOR DEEP WORK AND STUDY
• Hundreds of studio tracks across lofi, deep house, cinematic, atmospheric, electronic, piano, post-rock and more, each with its own artwork
• Focus music built for concentration: a 16 Hz pulse in Focus, slower pulses for Relax, Meditate and Sleep
• Pure Signal: the pulse alone, generated live on your phone
• Choose how strongly the pulse leads: Low, Medium or High

REAL NATURE SOUNDS AND NOISE
• Rain, storm, rainforest, ocean, wind, campfire and night chorus, from real field recordings
• White, pink, brown and green noise
• Layer up to three under any track, with their own volume
• Solfeggio tones, one at a time

POMODORO AND SESSION TIMERS
• A built-in Pomodoro timer: 25-minute work blocks and short breaks, with the music easing into Relax for each break
• 25 and 50-minute sessions, or Infinite Play
• Sessions end with a slow fade, never a jolt

SLEEP SOUNDS AND A SLEEP TIMER
• Sleep mode slows the pulse to delta-range swells
• Set a sleep timer and lock the phone; LockIn fades out when it ends
• Lock-screen controls, so the phone can stay face down

A DJ WHO KNOWS WHEN TO TALK
John Obidi drops in between tracks with a word to keep you going, or switch him to Mostly music. In Sleep and Meditate he says a soft hello, then keeps the quiet.

STAY ON TRACK
• Your streak and your week at a glance
• An optional 7 PM reminder when one session would keep your streak going
• Sticky notes and a task list for the thoughts that interrupt deep work
• Heart what you love; thumb a track down and it leaves your rotation

NO HEADPHONES REQUIRED
LockIn uses amplitude modulation rather than binaural beats, so it works on any speaker. Headphones make it more immersive.
