How Soma compares
Rings and watches read a few signals all day. Clinic scans read much more, less often. Soma Axon is being built to read the whole body every week, in a few minutes. Here's where each one fits.
| What it is | How often | Price | Medical status | Available | |
|---|---|---|---|---|---|
| Soma Axon | A closed pod you step into for a whole-body scan, and an iPhone app between visits | Once a week, for a few minutes. The app reads your phone and watch in between | Not announced. It'll be priced like a weekly habit | General wellness: not a medical device, not cleared by the FDA, and it doesn't diagnose | Not yet. The first prototype is being built, and the waitlist hears first |
| Neko Health | A health check in a clinic: an hour of sensors, cameras and a blood draw, then a clinician goes through the results | As often as you and your clinician decide. Neko's returning members came back about a year later | $499 a scan in New York, HSA and FSA accepted | Medical care, with licensed clinicians, a certified lab on site and referrals | Yes. Stockholm since 2023, then the UK, and New York since September 24, 2026 |
| Apple Watch | A smartwatch worn day and night, paired with an iPhone: Series 12, Ultra 4 or SE 3 | All the time. Series 12 and Ultra 4 take your heart rate every five seconds, and sleep is read every night | From $249 (SE 3), $399 (Series 12) or $799 (Ultra 4), with no subscription for the health features | ECG, irregular rhythm, AFib History, sleep apnea and hypertension notifications are cleared by the FDA. Blood oxygen, Vitals and temperature are for wellness only | Yes. Series 12 and Ultra 4 went on sale on September 18, 2026 |
| Oura Ring | A smart ring worn day and night, with the Oura app | All the time. Sleep, Readiness and Activity scores every day, and heart rate every five minutes while you're still | Ring 5 from $399 and Ring 4 from $349, plus a membership at $5.99 a month or $69.99 a year | Oura says the ring isn't a medical device, and it has no FDA clearance of its own | Yes. Ring 5 has shipped since June 2026 |
| Whoop | A screen-free band worn around the clock, WHOOP 5.0 or WHOOP MG, with a phone app | All the time. Recovery, strain and sleep scores update every day, and WHOOP MG takes an ECG when you ask | A yearly membership with the device included: One $199, Peak $239, Life $359 | The ECG on WHOOP MG is cleared by the FDA. Whoop says its blood pressure insights aren't a medical device, and its other scores have no FDA clearance | Yes. WHOOP 5.0 and WHOOP MG have been sold since May 2025 |
| Ultrahuman Ring PRO | A smart ring worn day and night, with the Ultrahuman app | All the time. HRV and skin temperature around the clock, heart rate through the day and sleep every night | $479 with its charging case, and no subscription for your data. Some add-ons cost extra | Ultrahuman says the ring and app aren't medical devices, and it has no FDA clearance of its own | On pre-order in the US, shipping from October 10, 2026. The older Ring AIR can't be imported |
| Withings BodyScan 2 | A smart scale with a handle, with the Withings app | A 30-second Daily Scan each morning and a 90-second Longevity Scan once a week | $599.95, HSA and FSA eligible.
