Quick Answer
Snollo and SnoreLab solve different problems. SnoreLab is the most established dedicated snore recorder available for iPhone, with a strong track record and a recognizable “SnoreScore” metric. Snollo is the better choice if you want Apple Watch sleep stage tracking alongside snore detection, on-device privacy (zero cloud upload of audio), and a free tier with no weekly recording limits.
If bedroom audio privacy is your main concern — because it should be — Snollo is the clear winner. SnoreLab processes audio on its servers; Snollo never sends audio off your device.

What SnoreLab Does Well
SnoreLab has been on the App Store since 2012 and has recorded over 170 million nights of sleep. That longevity has produced a mature product with a few genuine strengths:
The SnoreScore. SnoreLab’s proprietary “SnoreScore” compresses a full night of snoring data into a single number that users can track over time and compare against factors like alcohol, body position, or illness. It’s simple, memorable, and easy to share with a doctor.
Remedies tracking. SnoreLab lets you log factors like whether you used a nasal strip, elevated your pillow, or avoided alcohol — then correlates those variables with your SnoreScore over time. This is a genuinely useful feature for people trying to identify what reduces their snoring.
Large dataset for comparison. Because SnoreLab has been running for years, it can benchmark your snoring against population data. If your SnoreScore is in the 95th percentile, that context matters.
Doctor reports. The app can export a PDF report showing your snoring patterns over time, which some users find useful when discussing sleep apnea concerns with a physician.
Where SnoreLab Falls Short
No Apple Watch integration. SnoreLab is a pure microphone app. It does not read from Apple HealthKit and cannot tell you anything about your sleep stages, heart rate, or HRV. If you wear an Apple Watch to bed, that data is invisible to SnoreLab. This is a significant gap for users who want a complete picture of their sleep.
Cloud processing. SnoreLab analyzes your audio on its servers, not on your device. This means your bedroom audio — hours of it, every night — is transmitted over the internet and stored on SnoreLab’s infrastructure. Common Sense Privacy has flagged SnoreLab for unclear data practices. If you record in a bedroom where partners or children are also sleeping, this matters.
Free tier is restrictive. The free version of SnoreLab limits recording to one night per week. For any meaningful pattern recognition, you need consistent nightly data — which requires a paid subscription.
No sleep stage information. SnoreLab tells you how much you snored. It cannot tell you whether you snored more during REM sleep, whether your snoring correlated with elevated heart rate, or whether it coincided with micro-awakenings. For those insights, you need Apple Watch data, which SnoreLab doesn’t use.
What Snollo Does Differently
On-device CoreML processing. Every sound Snollo records is classified on your iPhone by a machine learning model running locally. Raw audio is processed in device memory, and only the metadata (timestamps, sound categories, intensity) is saved — to your private iCloud container. Snollo has no servers and no access to any of this data.
Apple Watch sleep stages. When you wear Apple Watch to bed, Snollo reads heart rate, HRV, SpO2, and motion data via Apple HealthKit to produce a detailed sleep stage breakdown: how much time you spent in REM, Deep, and Light sleep, and how your snoring correlated with each stage. Knowing that your snoring is concentrated in Light sleep versus Deep sleep is actionable clinical context that SnoreLab cannot provide.
No weekly recording limit. Snollo’s free tier includes nightly snore detection with no restrictions on how often you can track. Seven days of history are included free. For users who want continuous monitoring, this is meaningfully better than SnoreLab’s one-night-per-week free tier.
Sound classification beyond snoring. Snollo classifies snoring, breathing patterns, coughing, and sleep talking — giving you a more complete picture of what’s happening in your bedroom overnight. Clips are saved and available for playback.
Privacy: The Deciding Factor for Many Users
If you’re recording 6–8 hours of audio in your bedroom every night, where that audio goes matters enormously.
SnoreLab sends your bedroom audio to its servers for processing. Its privacy policy and App Store privacy labels indicate that data may be used for analytics and shared with third parties under certain conditions. Common Sense Privacy’s evaluation of SnoreLab raised concerns about data-sharing practices that SnoreLab has not fully addressed publicly.
Snollo’s architecture makes server-side sharing technically impossible. The CoreML model runs on your iPhone. The classified metadata — not audio — is stored in your personal iCloud container using CloudKit, which is encrypted end-to-end. Snollo’s own developers cannot access it.
For users in shared bedrooms, this difference is especially significant. If your partner’s voice is also being recorded overnight, their data is in the audio too.
Pricing Comparison
SnoreLab:
- Free: 1 recording night per week, basic SnoreScore
- Premium: ~$4.99/month or ~$39.99/year (pricing may vary by region)
Snollo:
- Free: Nightly snore detection (no weekly limit), sleep stage tracking via Apple Watch, Apple Health sync, 7-day history
- Premium: $4.99/month or $29.99/year — adds extended sound library (50+ sounds), unlimited history, advanced AI recommendations
Who Should Use SnoreLab
SnoreLab is the better choice if:
- You want a well-established snore score with a long historical track record
- You actively use the remedies-tracking and correlation features
- You need doctor-ready PDF reports of your snoring history
- You don’t own or use an Apple Watch
- Privacy is not a primary concern
Who Should Use Snollo
Snollo is the better choice if:
- You want snore detection that never uploads your bedroom audio to a server
- You own an Apple Watch and want sleep stage data (REM, Deep, Light) alongside snore detection
- You want free nightly tracking without weekly recording limits
- You want Apple Health integration for a complete health picture
- You share a bedroom and have concerns about other people’s voices being recorded in the cloud
Bottom Line
SnoreLab has a decade of refinement and a recognizable snore score metric. Snollo brings Apple Watch sleep stage integration and genuinely private on-device processing to a category where privacy has been an afterthought.
If you’ve been using SnoreLab and are comfortable with cloud audio processing and the limitations of a microphone-only app, it’s a reasonable choice. If you want your bedroom audio to stay on your device, and you want to understand how your snoring relates to your sleep stages, Snollo is the better fit.
Your audio never leaves your phone. That’s the sentence SnoreLab can’t say.
