Ambi generates calm soundscapes in real time — not from recorded loops. White, pink, brown, and water noise are synthesized live, so the sound never repeats and never seams. Drag the orb to blend all four sources, fine-tune with an 8-band EQ, and add reverb and motion until it feels right. BUILT FOR REAL LIFE Pick your use case on first launch — Sleep, Focus, Study, Baby, or Tinnitus — and Ambi loads a starter preset with a suggested timer. Seven beautiful presets are included; switch freely and explore. FREE TO PLAY • Play, mix, and explore all default presets • Blend four live noise generators with the orb • 8-band EQ, reverb, and motion • Set a sleep timer (hours, minutes, seconds) PREMIUM — ONE-TIME UNLOCK • Start the sleep timer • Background play and lock screen controls • Save, create, and manage custom presets • Siri, Shortcuts, and Control Center WHY AMBI? Most sound apps loop short recordings. Ambi uses algorithmic noise generation — smaller download, infinite variation, and a mix that responds to you in real time. Whether you need brown noise for deep focus, pink noise for baby sleep, white noise for study, or gentle water for tinnitus relief, Ambi is a simple, beautiful sound machine in your pocket. No subscription. No ads. Just calm.
