Nagi
Record your night, sound and sleep score, with your phone
For anyone who worries about snoring or the sounds of the night. Nagi measures your night's loud minutes with your phone's microphone and plays you the loudest moments in the morning. If you wear a watch or a ring at night, the sleep record it wrote stands beside the sound. No diagnosis, no judging, no guessing: you hear your own recording.
Hey everyone, maker here.
I kept waking up not knowing if I'd snored, coughed all night, or slept through it fine, and every app that claimed to answer that wanted a wearable or a subscription before it would tell me anything.
So I built Nagi: it records your night with just your phone's own microphone, no extra hardware, and plays back the loudest moments in the morning so you actually hear what happened.
Everything is processed on the device, nothing is uploaded. If you already wear a watch or ring at night, its sleep data shows alongside the sound, so you get the "what happened" and the "how you slept" in one place, with trends and history over time.
Building it from Japan first, where snoring and hay fever season drive a lot of the search volume that most sleep apps in English miss.
Free to record. Would love to hear what you think, and happy to answer anything about the on-device processing or the Japan-first approach.
