Nightgrit records the sounds of your night. Start it before you sleep and it listens until you stop it, marking every burst of grinding it hears. The next morning you can scan the timeline, play back any marked clip, and correct anything it got wrong.
Recording and analysis run entirely on your iPhone. Your audio stays on the device.
Nightgrit is a sound recorder, not a medical device. It does not diagnose or treat anything and does not give medical advice. What it marks is for your own reference only.
