Samsung Galaxy Watch
Per-night sleep stages, sleep score, overnight SpO2, heart rate, HRV, respiration, and snoring from your Samsung Health export. Read locally, never sent anywhere.
Read your Samsung Health export, joined to your CPAP nights
A Galaxy Watch records sleep stages, heart rate, HRV, respiration, and, on models with the sensor, overnight blood-oxygen estimates. Samsung Health shows you these numbers; CPAP Clarity is what you import them into when you want them sitting next to your CPAP therapy data on the same calendar night.
The import path is the Samsung Health Download personal data export. Request it from the app settings, then drop the folder (or a .zip of it) onto the Dashboard import zone. CPAP Clarity reads only the per-night sleep files in your browser and stores the summaries in your browser's IndexedDB. We cannot write to your Samsung account, and the export is never retained outside your browser tab.
Once imported, the dashboard joins each Samsung night to the CPAP session on the same date. A night with high CPAP leak that also shows reduced REM percentage and lower overnight SpO2 tells a richer story than either source alone.
How to read these numbers
Sleep stages (deep, REM, light, awake) are estimated from movement and pulse pattern, not measured by EEG. Read them as a relative night-to-night trend; they do not substitute for sleep-lab scoring. Sleep scoreis Samsung's proprietary 0-100 rating. SpO2, HRV, and respiration are estimates from a wrist wearable, not calibrated medical measurements. Snoringis Samsung's own microphone estimate; it is not an apnea count and not an AHI.
These are wellness measurements, not clinical signals. Use them as one more data point in conversation with your sleep physician, not as a replacement for the CPAP data your machine records.
Frequently asked questions
How do I export my Samsung Health data for CPAP Clarity?
In the Samsung Health app, open Settings, then Download personal data, and confirm. Samsung saves a folder of files to your phone (it can be large). Move that folder, or a .zip of it, to the device you use for CPAP Clarity and drop it onto the Dashboard import zone. CPAP Clarity reads only the sleep files in your browser; nothing is uploaded.
Does CPAP Clarity connect to my Samsung account?
No. CPAP Clarity reads the export folder you download yourself, not the Samsung Health cloud or any API. There is no login and no live connection. To pick up new nights you re-download your data and re-import. The trade-off is full control: your Samsung data only leaves your phone when you choose to export it, and it never touches our servers.
Which Samsung watches does this work with?
Any Galaxy Watch whose sleep data lands in Samsung Health, including the Watch4, Watch5, Watch6, and Watch7 lines. Sleep stages, sleep score, heart rate, and HRV come from watches that record detailed sleep. Overnight SpO2 appears on models with the blood-oxygen sensor enabled overnight, and snoring detection needs your phone near the bed during sleep. CPAP Clarity reads whatever your export contains and leaves the rest blank rather than guessing.
Will Samsung sleep stages match what a sleep study showed?
Not exactly. Samsung estimates sleep stages from movement and heart-rate pattern, while a sleep study scores stages directly from brain and muscle signals. The two agree on overall structure but disagree on minute-by-minute scoring. Read Samsung sleep stages as a relative night-to-night trend, not an absolute label. A drop in REM percentage across several nights that also show high CPAP leak is meaningful even if the absolute minutes do not match a sleep lab.
What about Samsung's snoring and sleep-apnea features?
Samsung's snoring number is its own microphone estimate of time spent snoring. CPAP Clarity shows it only with clear framing: it is not an apnea count, not an AHI, and not a medical measurement. Samsung Health Monitor also has a separate, regulated sleep-apnea screening feature; CPAP Clarity does not import or display that result. Your CPAP machine's AHI is the number to discuss with your clinician.
Can I import years of Samsung data at once?
Yes. A Samsung Health export covers your full account history. CPAP Clarity reads the per-night sleep summaries and the stage timeline in your browser and joins each night to the CPAP session on the same calendar date automatically. The export is large, so the folder drop is smoother than the .zip on lower-memory phones.
