Build your own journey
Chain steps into a frequency curve — start in beta, glide to theta over twenty minutes, hold, then drop into delta. Most apps hand you fixed tracks. This one lets you author the whole arc.
Binaural beats · iOS
Design the frequency curve, not just the track.
Every other binaural app hands you a fixed recording. This one lets you chain steps — start in beta, glide to theta over twenty minutes, hold, then fall into delta — and hear the tone move the whole way.

Glide through every brainwave state
Delta through gamma, with the tone moving continuously rather than jumping. Scrub the curve mid-session to skip ahead or drop back.
Stay mind awake, body asleep
Journeys can pull gently back toward alpha at intervals, so a long theta sit keeps you present instead of letting you drift off.
Drift into real recorded scenes
Rain, ocean, wind, fire, night, beach and storm — recorded ambiences, not synthesised approximations. Set a different one per step, or none at all.
Recorded, not synthesised
Seven ambiences, each a long seamless loop rather than a short clip on repeat. Assign a different scene to every step of a journey — open over rain, then leave the listener with nothing but the tone.
- Rain · Steady rainfall on soft ground
- Ocean · Distant waves on a wide shore
- Wind · Air moving through open meadow
- Fire · A campfire burning low
- Night · Crickets under a summer moon
- Beach · Gentle waves on sand
- Storm · Shelter from distant thunder

What it is, plainly
A tone generator with a good curve editor and a solid ambience library. It plays two slightly different frequencies, one per ear, so you need headphones. People use it for meditation, lucid dreaming practice, focus work and getting to sleep.
It makes no claims about what brainwave entrainment will do for you, and it is not a medical device or a treatment for any condition. If you have epilepsy or a seizure disorder, speak to a doctor before using entrainment audio.
