Medical disclaimer: This article is for information only and isn’t medical advice. Wearables can’t diagnose conditions. Talk to a doctor about any health concern, and don’t change medication or care based on a wearable reading. FDA clearance or authorization of a feature means it met FDA requirements for its intended use. It doesn’t mean it will work for everyone or catch every problem.
The sticker price on a wearable is only half the story. Oura and Whoop both charge a membership, and Apple doesn’t require one. We added up what each costs over two years using the makers’ own pricing pages, plus cheaper alternatives.
Quick answer
Over 24 months, our math puts the Apple Watch SE 3 at $249 (no required subscription, but you need an iPhone), Whoop One at $398 (the device comes with the membership) and the Oura Ring 4 at about $489 (ring plus membership). If you want the lowest two-year cost and don’t need a premium brand, the Fitbit Air and Amazfit Helio Strap both list at about $100.
- Cheapest of the big three: Apple Watch SE 3, if you already use an iPhone.
- Screen-free and sleep-focused: Oura Ring (a ring, no screen) or Whoop (a strap, no screen). Both need a membership for full insights.
- Most features for the money: Apple Watch Series 12 at $399, which also has FDA-cleared heart features (details below).
Two-year cost: device plus membership
| Wearable | Device price | Membership | 2-year total (our math) | Notes |
|---|---|---|---|---|
| Apple Watch SE 3 | From $249 | None required | $249 | Needs an iPhone. Optional Apple Fitness+ is $9.99/month after any trial. |
| Apple Watch Series 12 | From $399 | None required | $399 | Adds ECG app, hypertension notifications and Blood Oxygen app vs SE 3 |
| Whoop One | Included | $199/year | $398 | Includes the WHOOP 5.0 device; lifetime warranty while your membership is active |
| Whoop Peak / Life | Included | $239 / $359 per year | $478 / $718 | Life includes the MG device with ECG and irregular rhythm features |
| Oura Ring 4 | From $349 list (on sale from about $244 when we checked Oct 30, 2026) | $5.99/month or $69.99/year | $488.98 (annual plan) | The first month is free for new members. Paying monthly, 23 paid months comes to about $487. |
| Oura Ring 5 | From $399 | Same | $538.98 (annual plan) | Newer model; some finishes cost $499 |
Prices are from apple.com, whoop.com and ouraring.com, checked October 30, 2026, before tax. Oura and Whoop both list their products as HSA/FSA eligible; check with your plan administrator. Prices and plans change, so check before you buy.
What the math leaves out: bands, chargers and cases (Oura sells a charging case for $99), AppleCare, and trade-in credit. If you’d only keep Oura or Whoop for a year, Whoop’s model is cheaper to quit, because there’s no upfront device cost. Whoop says you can cancel and return within 30 days of receipt for a full refund minus shipping.
What each one measures (per the maker)
This is what each company says its device tracks. It’s not our assessment of accuracy.
- Oura Ring: Oura says the membership covers “over 50 health metrics” including sleep, activity, stress, heart health and women’s health. Its Readiness Score uses temperature trends, heart rate and sleep, and Ring 4 battery life is listed as 5–8 days (Oura).
- Whoop: Sleep, Strain and Recovery scores, VO2 max and heart rate zones, and Women’s Hormonal Insights, with a battery of 14+ days. Whoop describes the ECG and irregular heart rhythm notifications on its Life tier as “medically regulated” features. It also says Blood Pressure Insights “is not a medical device” (Whoop).
- Apple Watch: Series 12 lists HRV, the ECG app, irregular rhythm notifications, hypertension notifications, sleep score, sleep apnea notifications, the Blood Oxygen app and wrist temperature sensing. The SE 3 drops the ECG app, hypertension notifications and Blood Oxygen app. Battery life is listed at up to 24 hours on Series 12 (Apple).
Which features are FDA-authorized?
Most wellness scores (sleep, readiness, recovery, strain) aren’t medical devices. A few Apple features have FDA authorization, which we checked in the FDA databases:
- The ECG app was granted De Novo classification DEN180044, and the irregular rhythm notification feature DEN180042, both in September 2018.
- The Hypertension Notification Feature was cleared under 510(k) K250507 on September 11, 2025. It’s a notification feature; it doesn’t give you a blood pressure reading.
On Whoop’s blood pressure feature: the FDA sent Whoop a warning letter about Blood Pressure Insights in July 2025. In June 2026, after Whoop changed the feature and its labeling, the FDA said it does not intend to enforce device requirements for the modified version, under its updated general wellness guidance (FDA, June 17, 2026). In other words, it’s treated as a wellness feature, not a medical measurement.
Not medical advice. Wearables can’t diagnose conditions, and a normal reading doesn’t rule anything out. Talk to a doctor about any health concern, and don’t change medication or care based on a wearable.
Ring vs strap vs watch: form factor
- Ring (Oura, Galaxy Ring): no screen and easy to wear to bed. You check everything in the phone app, and you need the right ring size, so use the sizing kit if one is offered.
- Strap (Whoop, Amazfit Helio Strap): no screen, and it can be worn on the wrist or upper arm. Whoop lists 14+ days of battery.
- Watch (Apple Watch, Fitbit): a screen for notifications, apps and workouts, but you’ll charge it more often (up to 24 hours listed for Series 12).
Cheaper alternatives
| Alternative | Type | Price (maker, checked Oct 30, 2026) | Subscription | 2-year cost |
|---|---|---|---|---|
| Amazfit Helio Strap | Screenless strap | $99.99 | “No required subscription” (Amazfit) | $99.99 |
| Google Fitbit Air | Tracker | $99 ($129 Special Edition) | 3 months of Google Health Premium included; then $9.99/month or $99/year, optional | $99 (free tier) to about $297 (keeping Premium on annual plans) |
| Samsung Galaxy Ring | Ring | From $299.99 before trade-in | Samsung hasn’t required one at launch (9to5Google, 2024) | From $299.99 |
These are alternatives for the same job (sleep and activity tracking), not identical devices. Feature sets and app ecosystems differ, so check that the one you pick works with your phone.
Worth it?
If you have an iPhone and want one device for everything, the Apple Watch is the best value over two years: $249 to $399 with no required subscription. Oura and Whoop make sense if you specifically want a screen-free ring or strap and you’ll use the membership insights. Count on $400 to $500 over two years, and more on Whoop’s higher tiers. If you just want sleep and step tracking on a budget, a $100 tracker does the basics for a fraction of the cost.
How we researched this
This comparison is researched, not a hands-on review. We took prices, membership fees and feature lists from apple.com, whoop.com, ouraring.com, samsung.com, amazfit.com and Google’s announcements on October 30, 2026, and checked every FDA authorization in the FDA’s own databases. The two-year totals are our own arithmetic.
FAQ
Which is cheapest over two years: Oura, Whoop or Apple Watch?
On list prices checked October 30, 2026, the Apple Watch SE 3 is cheapest at $249 with no required subscription. Whoop One is $398 (two years of membership, device included), and the Oura Ring 4 is about $489 with the annual membership.
Does the Oura Ring need a subscription?
Oura says the membership ($5.99 a month or $69.99 a year in the US, with the first month free for new members) is needed to unlock its full insights. Check Oura’s page for what works without it.
Do you have to buy the Whoop device?
No. The Whoop 5.0 device comes with the One and Peak memberships, and the MG device with Life. You pay $199, $239 or $359 a year.
Are these wearables FDA-approved?
Most of their scores are wellness features, not medical devices. Apple’s ECG app and irregular rhythm notifications have FDA De Novo authorization, and its hypertension notifications are FDA-cleared (K250507). Whoop calls its ECG and irregular rhythm features on the Life tier “medically regulated”.
Is there a cheaper Oura or Whoop alternative?
Yes. The Amazfit Helio Strap ($99.99, no required subscription), Google’s Fitbit Air ($99) and the Samsung Galaxy Ring (from $299.99) all track sleep and activity for less over two years.
