Lumora: Sleep Sounds & Focus

Lumora is not a medical device and does not diagnose, treat, cure, or prevent any condition. Sounds are for relaxation and ambient listening only.

Lumora loops a calming base sound mixed with a real-time synthesized frequency, so you can build the perfect soundscape for sleep, focus, study, meditation and relaxation.

🌙 A library of sounds
Nature field recordings (forest, rain, ocean waves), Tibetan singing bowls and gongs, calm piano and classical, plus gentle chill and meditation music — all looping seamlessly with no gaps.

🎚️ Mix it your way
Blend the base sound and the frequency with independent volume sliders, or balance both with a single mix control. Save your favorite mixes.

🔊 Frequencies to explore
Binaural beats, isochronic tones, amplitude modulation and pure tones. Named after EEG bands (Delta, Theta, Alpha, Beta, Gamma) or alternative tunings — offered purely to explore, with no proven effects.

⏱️ Sleep timer
Fades out and stops after your chosen time. Screen-off playback with handy notification controls.

🎧 Headphones
Recommended for the binaural sounds, where each ear hears a slightly different tone.

Great as a background for sleep, study, work, reading, yoga or meditation. Blend white noise, pink noise, brown noise, nature sounds and calm music, exactly the way you like.
