Snore Timeline for Android

What the Android app includes

The Android app shares the core of the iPhone version. While you sleep, a sound classifier on the phone listens to the microphone and labels what it hears. You get:

• Sound detection. The app recognizes snoring, gasps, coughs, sneezes, sleep talking, and breathing, along with louder distress sounds. Each detection lands on the timeline. How Detection Works covers the labels.
• An interactive timeline. Your night is drawn as a waveform you can zoom from 1-second detail out to a 1-hour overview, with decibel readings in approximate dB SPL. A calendar lets you jump to any recorded night. See Timeline & Playback.
• Episodes and events. Snores close together get grouped into episodes, and a 30-second gap starts a new one. Episodes & Events explains the grouping.
• Breathing disruption detection. After a minute of audible breathing, the app watches for silent stretches of 10 seconds or more, then confirms with a recovery sound. Disruptions are marked on the timeline. It's audio analysis, and it isn't a medical test. See Breathing Disruptions.
• Sleep stages and a hypnogram. The app estimates awake, light, deep, and REM stages from your breathing and movement sounds and charts them across the night. See Sleep Stages.
• A sleep score and weekly trends. Each night gets a score out of 100 plus sleep efficiency, wake-after-sleep-onset, and respiratory rate, with a weekly view that compares nights. See Sleep Score.
• Audio playback and exports. Play back any moment, export a full night or individual episode clips, and build a report with summaries, sleep phases, events, and audio across a date range. See Export & Sharing.
• Recording quality and storage controls. Choose from three quality tiers and set an optional storage limit so old nights clear out on their own. See Storage & Quality.

Everything runs on your phone. No accounts, no cloud uploads. The Privacy Policy has the details.

How it differs from iPhone

A few features are platform-specific. This is what changes when you move from iPhone to Android.

Not on Android:

• No Apple Watch or wearable support. The watch app, live wrist view, and watch biometrics are iPhone-only. The Android app records from the phone's microphone. See Apple Watch & Wearables for the iPhone side.
• No Siri or Apple Shortcuts. Voice control and the Shortcuts automations described in Siri, Shortcuts & Widgets don't exist on Android.
• No Apple Health. Android writes to Health Connect instead (see below).
• No home-screen widgets.

Android equivalents and extras:

• Health Connect. When you turn it on, the app writes your sleep session and stages, plus your estimated respiratory rate, to Health Connect, where other apps can read them with your permission.
• App shortcuts. Long-press the app icon for quick actions: start a recording, stop one, jump to last night, or open your weekly summary.
• A bedtime reminder. Set a nightly time and the app reminds you to record.
• A recording delay. If you'd rather not record yourself falling asleep, set a delay of up to 180 minutes in 5-minute steps. Nothing during the delay is saved.
• A wake alarm. The app can wake you in the morning.

Where your files are saved

When you export audio, the files go to your phone's Downloads folder, sorted into two places by date:

• Downloads > Exported Recordings holds full-night audio files, each named with the date and length.
• Downloads > Snoring Episodes holds individual episode clips.

To find them:

1. Open your phone's Files app.
2. Go to Downloads.
3. Open Exported Recordings or Snoring Episodes, then the dated folder inside.

Since the files are in Downloads, any app that can read your downloads can open or share them. The Export Report sheet bundles summaries, sleep phases, events, and optional audio for a date range and lets you share the result straight from the app. Export & Sharing covers the full report.

Battery and background setup

Recording runs for hours with the screen off, so Android's power management matters more here than it does for most apps. A few things keep an overnight session alive.

Let the app run without battery restrictions. When the app notices it isn't exempt from battery optimization, it shows a dialog titled "Improve Recording Reliability" and offers to open the right system screen. Tap Allow and confirm. Once the exemption is granted, Android stops putting the app to sleep mid-recording. If you tapped "Not Now," you can grant it later from your phone's app settings under battery.

Keep the recording notification visible. While the app records, a notification reads "Recording" with the elapsed time, plus the Bluetooth device name if you're recording through one. That notification is what lets Android keep the microphone running in the background. Don't dismiss it or block the app's notifications, or the recording can get cut short. That's why the app asks for notification permission.

• Plug the phone in. Overnight recording works on battery, but charging takes away any chance of Android closing the app to save power.
• Put the phone face-down on a nightstand 30 to 60 cm from your head. That keeps your breathing audible, which disruption detection and sleep stages both depend on.
• Watch out for aggressive power management. Some manufacturers add their own app-killing layer on top of Android. If recordings keep stopping overnight, look in your phone's settings for a per-app battery or background option and set Snore Timeline to unrestricted.

The app also looks after the session by itself. If a phone call or another app grabs the microphone, it tries to resume. If you switch to or from a Bluetooth device overnight, recording restarts on the new microphone. If a recording still cuts out, Troubleshooting walks through the causes.
