Luten
Sound that learns what calms and focuses you
Luten is an iPhone app that learns which sounds calm and focus you, instead of handing everyone the same playlist.
Tell Sona, the built-in companion, how you feel in plain words and Luten picks a soundscape for one of five modes: Sleep, Focus, ADHD, Stress or Kids. An on-device recommender builds a Sound DNA profile from what you play, skip and favorite, so what Luten suggests gets more yours the more you use it.
Sona runs entirely on the device using Apple's NaturalLanguage framework, so nothing you type and nothing you listen to leaves your phone. No vocals, no talking, no guided courses, no ads.

I built Luten because every sound app I tried handed me the same playlist as everyone else, and then asked me to finish a course. Luten does one thing. You tell Sona how you feel in plain words and it picks a soundscape for you. That runs on the phone using Apple's NaturalLanguage framework, so nothing you type and nothing you play leaves the device. The more you play, skip and favorite, the more the suggestions bend toward you. The part I did not expect to matter most was the 3am wake up. It came up again and again in testing, and almost nothing out there is designed for it. Happy to answer anything about the on-device side. That is the piece I spent the most time on.
The on-device Sound DNA approach is a real differentiator. Personalization that learns from skips and favorites without shipping every play to a server is both faster and better for battery, and the five-mode framing (especially ADHD and Stress) matches how people actually search for sound apps rather than forcing one playlist model. Curious whether the Sleep mode fades tracks automatically or relies on the native timer.
Running Sona fully on-device with NaturalLanguage is the detail I'd lead with — "nothing you type leaves your phone" is a much stronger promise than another calm-sounds playlist, and it's the kind of thing people actually check before typing how they feel. The Sound DNA profile is a smart retention loop too, since the app gets more personal the longer you stay. Curious how you'll handle the ADHD mode positioning; that audience is picky and will tell you fast if the soundscapes miss.
