Does snoring mean I have sleep apnea?

Not necessarily. Snoring is caused by airway vibration and can happen on its own, with no related condition. Nightsong is a wellness tool for seeing how your own snoring and breathing change over time against your baseline. It does not screen for or diagnose sleep apnea. If your snoring is loud or frequent, or a partner notices pauses in your breathing, that is a conversation for your doctor.

How many nights of data do I need before the numbers mean something?

A single night is a snapshot; a week begins to show a pattern. Most people find that seven to fourteen consistent recordings are enough to see how variables like alcohol, late meals, and sleep position shift their personal baseline.

Can sleeping position affect how much I snore?

Yes. Back sleeping tends to increase snoring frequency and volume because gravity pulls soft tissue toward the airway. Tracking position alongside sound levels lets you see the difference across your own nights rather than relying on a population average.

Is on-device tracking as useful as a lab study?

They answer different questions. A lab study captures one night in clinical detail; on-device tracking captures your real environment across many nights. Consistent home recording often reveals behavioral patterns, such as the effect of a late meal or a stressful day, that a single-night lab visit cannot.

Why does Nightsong keep recordings on my phone only?

Your bedroom audio is private. Nightsong records, analyzes, and scores your night entirely on your iPhone. Nothing is uploaded, there is no cloud copy of your audio, and you own your data.

Learn the Night: The Quiet Science of Better Sleep

Around 45% of adults snore occasionally, and roughly 25% snore every night (American Academy of Sleep Medicine, 2023). Most people have never heard themselves, and fewer still know what their own baseline sounds like. This collection of guides answers the questions that come up after a bad night: what snoring actually is, why a single recording tells you almost nothing, and how consistent, private tracking on your iPhone can reveal patterns that a one-off sleep study cannot. Each article is self-contained, so you can start with the topic that brought you here or read them in order from first principles to practical habit changes.
