FAQ

NightSnore is free to download. Monitoring is unlimited, and every morning you get the full report — snore score, event count, duration and the whole-night chart — at no cost.

A single one-time unlock — still no subscription — adds unlimited history, multi-night trends, snore playback, the full-screen analysis chart and PDF/CSV export. The free version keeps your 3 most recent nights; earlier nights are never deleted and come back the moment you unlock. Current pricing is on the App Store page and may vary slightly by region.

The one-time unlock is discounted right now and steps back up to its regular price over the coming weeks:

Period	USD	CNY
Now – Sep 17	$2.99	¥15
Sep 18 – Oct 17	$3.99	¥18
Oct 18 – Nov 17	$4.99	¥25
From Nov 18	$5.99	¥25

In mainland China the regular price applies from October 18 — one month earlier than elsewhere, because the App Store price tiers for CNY have no step in between. Prices in other currencies and their change dates may differ slightly; the price shown in the App Store always applies.

NightSnore used to be a paid download. Since version 3.0 it is free to download: monitoring is unlimited and the full morning report costs nothing, while unlimited history, multi-night trends, snore playback, the full-screen analysis chart and PDF/CSV export moved to a single one-time unlock. It is still not a subscription — there are no recurring charges of any kind.

If you bought NightSnore while it was still a paid download, you keep the full version permanently. After updating, the app recognises your original purchase by itself — you never pay again, and there is nothing you need to switch on.

NightSnore requires iOS 17.6 or later. This covers the vast majority of iPhones in use today — if your phone received an iOS 17 update, you're good to go.

Compatible models include iPhone XS, XR, and all iPhone 11 through 16 models. No additional hardware required.

Less than you might expect. Because the screen stays off all night, NightSnore's actual battery impact is surprisingly low — around 1.5–2% per hour of monitoring on modern iPhones. On an iPhone 16 Pro, a full 7-hour session used just 12% of battery in real-world testing.

Monitoring duration	Estimated drain
4 hours	~6–8%
7 hours	~10–14%
9 hours	~13–18%

Older iPhone models or those with degraded batteries may use slightly more. Actual usage also varies by iOS version, ambient temperature and background activity.

NightSnore only records the audio snippets around detected snore events — not the full night. Recordings are saved in compressed AAC format at 32 kbps.

Snoring level	Recording per night
Mild (<10 events/hr)	~2–5 MB
Moderate (10–30 events/hr)	~5–20 MB
Severe (>30 events/hr)	~20–50 MB

Session statistics and event logs are stored separately in a local database and take only a few kilobytes per night.

Microphone recording and our lightweight on-device analysis put minimal load on the CPU. In normal room-temperature conditions, you should not experience unusual heat.

If you charge overnight, placing the phone on a hard flat surface (rather than a pillow or blanket) helps dissipate heat. Avoid covering the phone while it charges.

Place your iPhone on your nightstand or nearby surface with the microphone facing toward you, at a distance of roughly 20–50 cm (8–20 inches).

The microphone is typically located at the bottom edge of the phone. You don't need to prop it up or use a stand — lying flat on the nightstand works fine.

No. Once monitoring starts, you can lock your screen and put your phone down. NightSnore runs in the background all night using iOS's audio background mode.

A Live Activity appears on your lock screen with a running session timer, so a glance confirms monitoring is still active — no unlock required. Your snore count and detailed statistics stay in the app itself: open it any time during the night, or just read the full report in the morning.

NightSnore uses frequency and intensity analysis to distinguish snoring from other sounds — it doesn't just detect any loud noise. Events that don't match snoring patterns are logged separately as "other sounds," keeping your report clean.

For best results, place the phone closer to you than to your partner. The microphone naturally favors nearby sound sources over distant ones.

If your partner also snores, some of their events may appear in your report — there is currently no way to attribute sounds to a specific person.

NightSnore is designed and optimized for the built-in iPhone microphone. Using AirPods or a Bluetooth headset while sleeping is generally impractical, and audio routing behavior may vary.

We recommend using the iPhone's own microphone for the most consistent and reliable results.

Regular notifications and alerts do not affect monitoring. An incoming phone call may interrupt audio recording — to avoid any disruption, we recommend enabling Do Not Disturb or Sleep Focus before you start.

No. All audio capture and analysis happens entirely on your device using Apple's on-device frameworks. Not a single byte of audio ever leaves your iPhone.

Your session data, snore event logs and recordings are stored in your iPhone's local database. You can delete everything at any time from Settings → Delete All Data.

No account, no sign-up, no email address required. Open the app and start monitoring. It's that simple.

No. NightSnore is a personal tracking tool, not a medical device. It cannot diagnose sleep apnea or any other condition.

Its data — Snore Index, event timeline, multi-night trends — is designed to help you understand your patterns and have more informed conversations with your doctor. If you're concerned about your snoring or sleep quality, please consult a healthcare professional.

Snoring varies night to night based on sleep position, alcohol, fatigue, allergies and other factors. A single night is a data point, not a verdict.

We recommend monitoring for at least 7 consecutive nights to get a reliable baseline. The Trends view will show you patterns across multiple sessions once you have enough data.
