The best Whoop alternatives with no subscription

How WHOOP charges, and what stops when you cancel

WHOOP doesn't sell its band on its own. The hardware comes with a WHOOP membership, and the membership is the product. We tried to confirm WHOOP's current US tiers and prices on whoop.com on September 19, 2026, but every page we requested returned an error to our checker, so we don't print WHOOP prices here. Check the current figure on WHOOP's membership page before you compare.

What we could confirm is what happens when a membership ends. On WHOOP's own Community forum, a WHOOP staff account explained in October 2025 that your membership “will remain active until the end of your current commitment period or term,” and after that “WHOOP will no longer collect, upload, or analyze your biometric data” ( WHOOP Community). In plain terms: stop paying and the band stops working as a recovery tracker.

A no-fee ring works the other way round. You buy it once, and the app keeps showing your sleep, heart rate and heart rate variability (HRV) for as long as the ring works. That's the whole idea behind our no-subscription hub, and our guide to which smart rings require a subscription lays out every ring brand's fee policy line by line.

What a ring replaces, and what it doesn't

Most people shopping for a WHOOP alternative want the overnight numbers: sleep, resting heart rate, HRV and some kind of morning readiness read, without a watch face on the wrist. A ring covers that job well on paper. It sits on a finger all night, and every ring on this list tracks sleep, heart rate and HRV with no required fee.

Where a ring is weaker is exercise. The reviewer evidence on ring workout heart rate is thin and mixed:

• Gadgets & Wearables found the RingConn Gen 2 “consistently reported higher values” than a chest strap on runs, overestimating both average and maximum heart rate.
• DC Rainmaker found Oura Ring 5 workout heart rate “largely pretty good” on indoor cycling and road runs, but on a trail descent “the HR accuracy basically falls apart for the entire rest of the run.”
• Tech Advisor's Circular Ring 2 reviewer wrote: “I've not tested a smart ring that I really think does a good job of tracking heart rate during exercise.”

So if you used WHOOP mainly to track training load, plan on a chest strap for workouts and the ring for everything else. A strap is a one-time purchase too. Our best chest strap for HRV covers the options, and smart ring vs smartwatch helps if you're still weighing the form factor.

The fee math

Every ring below adds $0 in required fees for every year you own it. WHOOP's line would be its yearly membership multiplied by the years you wear it; since we couldn't verify that figure, the table shows Oura's membership, the other big fee-based wearable, for contrast. Ring prices change daily, so the last column links to the live price instead of printing one.

Our three-year cost breakdown runs the same numbers for every ring brand, and are smart rings worth it? covers who should skip a ring altogether.

How we ranked them

We started from our published ring rubric: required fees over three years (30%), evidence of accuracy (25%), claimed battery (15%), sizing and fit (10%), data ownership (10%) and phone support (10%). The reasoning behind each score is on our methodology page. For a WHOOP replacement we then leaned on two things the rubric doesn't weight directly: how rarely you'll need to take the ring off to charge it, since a band you never remove is the habit you're replacing, and whether the ring gives you a single morning readiness number.

That second test is why the Samsung Galaxy Ring ranks third despite a lower overall score (6.2/10) than the RingConn Gen 2 Air. Its Energy Score, which Samsung says calculates “your physical readiness based on yesterday's sleep, heart rate and activities,” is built for exactly that morning check, and the ring ships with a charging case. The catch is big: Energy Score insights need a compatible Samsung Galaxy AI phone, and the ring doesn't work with iPhone at all. If you're on iPhone, read our fourth pick as your third.

We haven't worn or lab-tested these rings. Everything here comes from the brands' spec, fee and warranty pages, named studies and attributed reviewer observations, all linked in the sources below.

The picks side by side

The picks in context

1. RingConn Gen 2

The best straight swap for a WHOOP band if you refuse a fee. RingConn claims 10-12 days per charge and up to 150 days with the included charging case, so you can top up from the case instead of hunting for a cable, and it works with iPhone (iOS 17+) and Android (10+). It's also the only ring here that a reviewer has lined up against a WHOOP: Gadgets & Wearables found resting heart rate correlated 98% and HRV 82%. Separately, a 2026 preprint (Tao et al., not peer-reviewed) found a heart rate bias of -0.42 bpm against a Polar H10 in seated athletes. The weak spot matters for ex-WHOOP owners who train: the same Gadgets & Wearables review found it read heart rate high against a chest strap on runs. Its “90.7% sleep apnea monitoring accuracy” is RingConn's own claim, and a ring is not a diagnosis. Our RingConn Gen 2 review goes deeper.

2. RingConn Gen 3

RingConn's current ring, with the longest claimed single charge of the rings sold on Amazon: up to 14 days (11-14 on RingConn's features page) and 150+ days total with its charging case. The Gadgeteer's reviewer got about 10 days with vibration alerts on. It adds Vascular Health Insights, Sleep Apnea Pattern Insights and Smart Vibration Alerts, and RingConn says plainly that it's “not a medical device.” Sizes run 6-15, but RingConn says Gen 3 sizes differ from its other rings, so use the Gen 3 kit even if you've owned a RingConn before. It ranks second because no validation study of Gen 3 itself exists yet, and it showed “Out of stock” on RingConn's own store when we checked (it was listed on Amazon). See our Gen 3 review or RingConn Gen 3 vs Gen 2.

3. Samsung Galaxy Ring

The best WHOOP alternative for Samsung phone owners. No subscription, a charging case in the box (up to 14 days total, per Samsung), sizes 5-15, a titanium frame, 10ATM and IP68, and an Energy Score that turns last night into a readiness number. Everyone else should read the fine print: it needs Android 11 or newer, Energy Score insights need a Samsung Galaxy AI phone, and Double Pinch and Find My Ring don't work on other Android brands. Samsung rates smaller sizes at up to 6 days per charge, and GSMArena got about 5 from a size 11. We found no peer-reviewed validation of the ring, which is the main drag on its score. Our Galaxy Ring review and best smart ring for Android go further.

4. RingConn Gen 2 Air

The cheapest way to drop a membership from a brand with a settled US legal status: RingConn lists the Air below Gen 2 and Gen 3 on its own store. You get up to 10 days per charge with 90-minute fast charging, sizes 6-14 (the same as Gen 2), iPhone and Android support, and no fee. You give up the charging case and sleep apnea monitoring (it “does not include sleep apnea monitoring,” per RingConn), and there's no validation of this model. For a WHOOP owner used to never taking the band off, the missing case is the real trade. Our Gen 2 vs Gen 2 Air comparison lays it out, and the Gen 2 Air review has the details.

5. Ultrahuman Ring PRO

The longest claimed battery we found: up to 15 days per charge and up to 45 days with the included PRO Charging Case, sizes 5-14 with a free kit, and, in Ultrahuman's words, “no recurring subscription fees for accessing your data.” Optional PowerPlugs cost extra (Cardio Adaptability is $24/year, for example), but none is required. It ranks last for practical reasons: it's a US pre-order from Ultrahuman's own store (“ships October 10th onwards” when we checked, after earlier dates slipped), it isn't sold on Amazon.com, Ultrahuman doesn't state its phone requirements on the US pages we checked, and the only accuracy data it publishes is an in-house pilot on the older Ring AIR that isn't peer-reviewed. Details in our Ultrahuman Ring PRO review.

What to check before you swap WHOOP for a ring

1. Your phone. Galaxy Ring is Android only, with its best features on Samsung phones. RingConn needs iOS 17 or Android 10 or newer. If you're on iPhone, our best smart ring for iPhone narrows it down.
2. Your size, measured with that brand's kit. A band fits any wrist; a ring doesn't. No brand says its sizes match another's, and every ring here offers a sizing kit. Our smart ring sizing guide explains why your jewelry size is the wrong starting point.
3. How you'll charge it. If you're used to wearing one device around the clock, a charging case lets you top up without hunting for a cable. RingConn Gen 2 and Gen 3, Galaxy Ring and Ultrahuman Ring PRO include one; Gen 2 Air doesn't. Our guide to chargers and charging cases covers the options, and smart ring battery life reads each maker's claim with its fine print.
4. Your workouts. If training load was the main reason you wore WHOOP, budget for a chest strap. Our ring vs chest strap test shows how to check a ring against one in a week.
5. Your WHOOP end date. Per WHOOP's staff reply, the membership runs to the end of your current commitment period or term. Time the switch so you aren't paying for a band you've stopped wearing, and check what WHOOP lets you keep before the membership ends.

Switching mistakes

• Expecting WHOOP's scores under the same names. Each brand builds its own scores from sleep, heart rate and HRV. The inputs are similar; the labels and formulas aren't.
• Trusting ring heart rate on hard or technical efforts. Reviewers found rings drifting on runs and falling apart on a trail descent. Wear a strap for training.
• Buying your jewelry size. A loose ring reads worse, and a tight one is miserable to sleep in.
• Assuming “no subscription” means no extras. Ultrahuman sells optional PowerPlugs, and Galaxy Ring puts some features behind a Samsung phone instead of a fee. Check whether a feature you want sits behind one.
• Treating battery days as a promise. Every figure on this page is the maker's claim under its own conditions. Reviewers got about 10 days from RingConn Gen 3 with alerts on and about 5 from a size 11 Galaxy Ring.

Where Oura fits

Oura isn't on this list because it charges a membership, which is exactly what you're trying to leave. It's still worth knowing why people choose it: in Dial et al., the Oura rings agreed with the chest strap more closely than every other device tested, WHOOP 4.0 included. Without the membership, though, Oura shows only three daily scores (Readiness, Activity and Sleep). Our Oura vs WHOOP comparison puts the two membership models head to head, and the best smart rings without a subscription ranks every no-fee ring, not just the ones that suit an ex-WHOOP owner.
