FAQ
Frequently Asked Questions About Sleep Tracking
Do I need an Apple Watch to use Snollo?
No — Snollo works as a sleep tracker for iPhone without an Apple Watch. Just place your iPhone on the nightstand and it will detect snoring via microphone. The Apple Watch adds more accurate heart rate data and detailed sleep stage breakdowns (REM, Deep, Light), but it is entirely optional.
How accurate is the snoring detection?
Snollo uses Apple's CoreML framework to analyze audio on-device in real time. In our testing, it accurately identifies snoring, breathing patterns, coughing, and sleep talking. You can listen back to any detected sound to verify it yourself.
Is my data secure?
Snollo processes everything on-device using Apple's CoreML. All saved data is stored in your private iCloud account. Snollo has no servers and no access to your audio recordings or sleep history.
Does it drain my battery overnight?
In our tests, overnight iPhone battery drain is typically 10–15%. We recommend keeping your phone plugged in if you use the continuous audio recording feature.
Does Snollo share my sleep data with anyone?
Snollo is built so it cannot access your data. All audio processing happens on your iPhone using Apple's CoreML. Recordings are stored exclusively in your private iCloud container. Snollo has no servers, no accounts, and no mechanism to transmit your sleep data — ever.
What sleep stages does Snollo detect?
Snollo tracks Light sleep, Deep sleep (slow-wave), and REM sleep using data from your Apple Watch heart rate and motion sensors. Each morning you get a full breakdown of your sleep architecture — how long you spent in each stage and how it compares to your personal baseline.
What's included without Premium?
The core app includes AI sound detection, basic sleep stages, Apple Watch integration, and 7 days of history — no subscription required. Premium adds unlimited recordings, full history, the complete sound library, and detailed weekly stats.
Does this sleep tracker work without Apple Watch?
Yes — Snollo is a sleep tracker for iPhone without Apple Watch. Place your iPhone on the nightstand and it uses the microphone for snoring detection, breathing analysis, and sound classification. Apple Watch adds heart rate-based sleep stages (REM, Deep, Light) but is entirely optional.
Can Snollo detect snoring without Apple Watch?
Yes. Sleep tracking with snore detection on iPhone works fully without Apple Watch. Snollo's on-device Core ML model analyzes microphone audio in real time — classifying snoring, breathing, coughing, and sleep talking. Apple Watch improves sleep stage accuracy but is not required for snore detection.
