Do you know what your breathing sounds like beyond your Fitbit sleep summary?
Do you know whether possible breathing pauses are scattered through your night?
Do you know whether the same breathing signs repeat on other nights?
WITH · COMPLEMENTARY DATA
Use your Fitbit sleep view. Look closer at your breathing.
Keep the Fitbit sleep information you value. SomniSense, a sleep apnea detector app, adds independent phone-audio analysis of signs of possible pauses and shallow breathing, organized in a report you can check yourself.
Hear the moments you want to understand
Open a marked moment to see its estimated time, duration and waveform, then hear the available sound before and after it. Go straight to a time instead of listening through the whole night.
See how the signs were distributed
Start with the report’s marked-sign counts and timing across the night. Your phone analyzes its own recording; the result does not explain or verify a Fitbit score.
Find out what repeats
With Pro, compare the frequency of marked breathing signs across nights. Optional tags keep routines beside your observations. Keep dates and recording coverage in view; differences are observations, not causes or treatment effects.
Use a compatible phone you already own—no extra device to buy or wear. Your first qualifying complete breathing report is free; retry free if a recording does not qualify. Recording and analysis remain free; later complete breathing reports and multi-night comparisons require Pro.
WHAT SOMNISENSE ADDS
Open the breathing moment, then hear the context
This screen shows a candidate region highlighted inside a selected minute, alongside playback controls and its position across the night.
- Candidate pause-like or shallow-breathing-like type, time, and model-estimated duration
- The marked waveform and playback of the sounds before and after the candidate interval
- Where each mark appears in the night, with Pro comparisons and structured reports to follow observations across nights
A mark is an acoustic model estimate, not a clinical diagnosis.

What Fitbit's been doing well for years
Fitbit devices offer sleep tracking and scores through the supported app and hardware. In May 2026, the Fitbit app became Google Health. Google’s current documentation describes sleep views and the features available for your device. Read Google’s sleep-tracking guidance.
Fitbit Sense and Versa 3 previously offered Snore Detection. Google says it is no longer available in the redesigned Google Health app. SomniSense gives you an independent way to review possible pauses and shallow-breathing patterns on your phone. See Google’s app changes.
What SomniSense adds, specifically
SomniSense uses the phone beside your bed to organize possible breathing pauses in a separate recording. You can inspect estimated times and durations and listen before and after the marked intervals, regardless of which Fitbit features your device supports.
Your marks are acoustic model estimates, not a clinical diagnosis. SomniSense’s BRI and a Fitbit sleep score keep their own meanings; one does not explain or verify the other.
Concretely:
- Go straight to a breathing moment — see its estimated type and duration, then hear the available surrounding sound.
- Review your snoring too — find it in the night and replay retained sound.
- Follow your own breathing record — compare your BRI across nights when continued observation is useful.
- Lifestyle Lab™ — compare nights with and without tags as an observational association.

| What did the room microphone capture? | Sense/Versa 3 Snore Detection is no longer available in the redesigned Google Health app | Marked possible pauses and shallow-breathing patterns, with available sound |
| Was my sleep score low for breathing reasons? | Neither product can establish the cause from these views alone | |
| Why was my deep sleep cut short? | Could be many reasons | Acoustic context only — not a causal answer |

If your Fitbit score and how you feel do not line up
Keep your sleep view and add breathing moments you can open and hear. Start with your own report rather than trying to explain a score from another app.
If the record is useful, you can choose more nights to see what repeats. Optional lifestyle tags help organize different nights for comparison; differences are observations, not causes.
Persistent daytime sleepiness, witnessed pauses or gasping deserve clinical attention, even when a consumer sleep score looks reassuring.
Put your phone by your bed and review your own night after sleep.
Your first complete breathing report is free to view—and stays free to revisit.

Common questions
- Will SomniSense replace Fitbit's sleep score?
- Keep your Fitbit sleep view for its own purpose. SomniSense adds independent phone-based breathing analysis with possible pause and shallow-breathing marks, a waveform and available surrounding sound.
- Do I need both?
- Add SomniSense if you want to inspect your own marked breathing moments. Your first complete breathing report is free, so you can see what the phone analysis adds before deciding whether you want continued full reports with Pro.
- Can the apps share data?
- No. The current product does not import Fitbit or Health Connect data. Compare the two apps manually by date.
- I have an older Fitbit. Does this still apply?
- Sleep features depend on your Fitbit and current app. Google renamed the Fitbit app Google Health in May 2026 and says Sense/Versa 3 Snore Detection is no longer available. SomniSense runs independently on a compatible phone.
