COMPARISON · COMPLEMENTARY, NOT COMPETING
SomniSense vs CPAP — they're not really comparable
CPAP is a medical treatment device for diagnosed sleep apnea. SomniSense is a wellness monitor that runs on your phone. Putting them in the same comparison table is a little like comparing a thermometer to ibuprofen — both relate to fever, but they're for different jobs.
The honest framing
If you've been searching "SomniSense vs CPAP," there's a decent chance you're somewhere in this loop:
You suspect something's wrong with your sleep. Your partner has mentioned it. You've Googled "do I have sleep apnea" at 1 a.m. The clinic visit is months out and expensive. The CPAP cost makes you nervous. You're wondering if there's a way to figure out what's actually going on first, before committing to either.
If that's where you are, the answer isn't "SomniSense or CPAP." It's: SomniSense first (to find out what's happening), then if your numbers say it's serious, the doctor visit, and possibly CPAP after.
If you already have a CPAP prescription, you don't need SomniSense for diagnosis — you need to use the CPAP. SomniSense can sit alongside as a same-scale sanity check on the nights you wear it (and the nights you don't).
The actual comparison, kept honest
| SomniSense | CPAP | |
|---|---|---|
| What it is | Wellness monitoring app | Medical treatment device |
| Diagnoses sleep apnea | No | Used after a sleep study diagnosis |
| Treats sleep apnea | No | Yes — positive airway pressure |
| What you wear | Nothing | Mask + tubing + machine |
| Setup time | 2 minutes | 4–8 weeks (study + Rx + fitting) |
| Cost (year 1) | $0–$50 | $500–$3,000 + supplies |
| Insurance | Not covered (consumer app) | Often covered with diagnosis |
| Travel-friendly | Phone only | Bulky but doable |
| Per-event audio playback | Yes — every event | No |
| Lifestyle Lab™ tagging | Yes — every night | No |
| Doctor-Ready Cadence™ PDFs | Yes — weekly + monthly (Pro) | Compliance report from machine |
The point of putting these side-by-side isn't to pick a winner. It's so you can see they answer different questions.
When SomniSense is the right place to start
You're undiagnosed and want to figure out what's actually happening. You're somewhere on the "I think I have a problem but I'm not sure" spectrum. SomniSense gives you 7 free nights of data, which is usually enough to know whether to escalate to a clinic or to try lifestyle changes first.
You want to run a 14-day experiment on yourself — alcohol, side-sleep, an anti-snore pillow — before committing to a treatment device.
You're tracking residual events on a CPAP — the nights you wore it, the nights you didn't, the nights the mask seal slipped.
When CPAP is the right answer
You've had a sleep study and you've been diagnosed with moderate-to-severe OSA. Your AHI is consistently above 15 (or above 30, in severe cases). Your sleep specialist has prescribed CPAP. Use it.
You wake gasping multiple times per night. Your partner has watched you stop breathing. You have OSA-related comorbidities — hypertension that doesn't respond to medication, cardiac issues, daytime sleepiness severe enough to affect driving. These are clinic conversations, not app conversations.
SomniSense isn't trying to be a substitute for any of this. If a doctor has told you to start CPAP, start CPAP.
I also tried an oral negative-pressure device for 30 days. About one in three nights I could actually sleep through it; the others my tongue was being held in a position my mouth didn't want. The takeaway from a few months of testing different interventions: every single one of them works if you can get used to it, and the percentage of people who actually do is smaller than anyone selling them tells you. SomniSense isn't replacing any of this — it's helping you find out whether the very serious step of trying treatment is the right one for you in the first place.
Cost, year one
| What you might pay | SomniSense Pro | CPAP (insurance) | CPAP (out of pocket) |
|---|---|---|---|
| Sleep study | — | $0–$500 copay | $1,500–$3,500 |
| Equipment | — | $0–$500 copay | $500–$1,500 |
| App / supplies (annual) | $49.99 | $0–$200 supplies | ~$200 supplies |
| Year 1 total | $49.99 | $0–$1,200 | $2,200–$5,200 |
The cost difference exists because they're different things. SomniSense is software running on hardware you already own. CPAP is a piece of medical equipment with a prescription, fitting, and ongoing supplies. The cheap option doesn't replace the expensive one — it just helps you know whether you need the expensive one.
SomniSense's first 7 days are free — cancel through the App Store or Google Play before day 7 and you won't be charged. The Year 1 total above assumes you keep the annual subscription past trial.

Common questions
- Can SomniSense replace a CPAP?
- No. CPAP is a treatment device — it pushes pressurized air to keep your airway open while you sleep. SomniSense is a monitor — it listens and reports. If you've been prescribed a CPAP, follow your prescription. SomniSense isn't trying to replace it.
- Can I use SomniSense to test if my CPAP is working?
- As a sanity check, sure. Your CPAP's own compliance report is more authoritative for treatment decisions, but if your CPAP says AHI 4 and SomniSense's BRI is also around there on the same nights, that's a useful agreement signal. They use the same per-hour event-rate scale.
- I have a BRI of 12. Do I need a CPAP?
- I don't give medical advice. A BRI of 12 corresponds to the "mild" range clinicians use for AHI. Many people in that range respond well to lifestyle changes (side-sleep, no late alcohol, weight loss) before needing CPAP. Some don't. That's a sleep specialist conversation. I built SomniSense to help you walk into that conversation with data, not to replace it.
- Is SomniSense covered by insurance?
- No. It's a consumer wellness app — $7.99/mo or $49.99/yr after a 7-day free trial. CPAP is covered when prescribed for diagnosed OSA.
- Can I use both at once?
- Yes — and a lot of people do. SomniSense will pick up the residual events on nights you forgot the mask, or the nights when the seal slipped, and will show you on a 30-day chart what your CPAP-on vs CPAP-off pattern looks like. Some Lab Members find this very motivating in the first weeks of CPAP.
