Oura vs WHOOP vs Ultrahuman: Sleep and Heart Rate

Q: Which tracker is best for resting heart rate on a GLP-1?

All three report overnight resting heart rate. Oura Ring 4 is the easiest start at plus a month; Ultrahuman Ring Pro has no subscription; WHOOP suits wrist wearers.

Q: Is Oura or Ultrahuman cheaper?

Oura charges a membership after the first month. Ultrahuman Ring Pro does not. I left the dollar figures off this page. Read each brand's membership terms before you buy.

Q: Can I buy an Ultrahuman ring in the US?

The Ring Pro, yes. US customs cleared its redesign in March 2026, and it is sold on Amazon by Ultrahuman US. The older Ring Air remains blocked from US import.

Q: Does WHOOP need a subscription?

Yes. WHOOP sells the band with a membership. I am not listing the dollar amounts here. The plans are on whoop.com, and I do not have a confirmed Amazon button for WHOOP.

The Wegovy label says resting heart rate can rise. These three can show you the night.

Oura Ring 4

Best for most people: a ring you'll wear to sleep, with a membership after month one.

The short answer

The Wegovy label says resting heart rate can go up and that it should be monitored. A ring or a strap won't diagnose that. It'll show you a trend you can take to your prescriber, which is the job I ranked.

I haven't worn this year's models for this update. I read the listings, the membership pages, and the notes on Ultrahuman's US sales. Scores sit lower for a tracker you won't wear, and a membership only pulls them a little, because the nightly heart-rate trend is the point.

How I ranked them

Overnight heart rate and sleep (45%). A clear morning resting-heart-rate trend sits at the top of the 7.8 to 9.6 band.
Comfort (25%). A ring most people sleep in sits higher than a strap they take off. Both stay in the band.
Ongoing cost friction (15%). No membership sits higher. A required membership sits lower inside 7.8 to 9.6. No dollar amounts on the page.
Training load (15%). Strain and recovery tools sit higher. They're not the main GLP-1 question.

I didn't link a WHOOP Amazon offer. The listing I checked wasn't sold by WHOOP.

1Best for most people

Oura Ring 4

9.0

The ring I'd wear to bed, plus a membership after the first month.

Best for: you want resting heart rate and sleep without a strap on your wrist.

Skip it if: you refuse a membership. Ultrahuman doesn't charge one.

Pete's take

I'd buy the ring I'll still be wearing on a Wednesday in February. Oura's morning heart-rate line is the trend I'd show a prescriber if the Wegovy label's heart-rate note made me nervous. The membership after month one is why Cost sits lower than a no-fee ring. I'm not putting the fee on this page. Size it with their kit. A size-8 listing isn't a promise it fits your finger. I haven't slept in a Ring 4 for this update.

More pros and cons

The morning resting-heart-rate line is the trend the Wegovy label is talking about.
A ring is easier to sleep in than a watch for a lot of people, so the log actually happens.
The Amazon listing is confirmed, so the ring has a real checkout.

The membership continues after the included first month.
Oura sizing is its own system, so order the kit before you lock a size.

2Best for people who won't pay a membership

Ultrahuman Ring Pro

8.6

A ring with no subscription, a step behind Oura on the morning habit.

Best for: you want overnight heart rate and you hate a monthly fee.

Skip it if: you want the app people already know how to read. That's Oura.

No membership

Pete's take

Ultrahuman wins the membership line, and that's a real reason to buy it. I still put Oura first because the GLP-1 question is whether you'll look at resting heart rate every morning, and Oura is the habit I see people keep. No fee is why this is #2 and not off the list. I didn't wear the Ring Pro. If a membership would make you quit in month two, buy this one and ignore my rank.

More pros and cons

There's no subscription, which is the whole reason to pick it over Oura.
The Amazon listing is sold by Ultrahuman, so the checkout is confirmed.
It's still a ring, so a full night of sleep is plausible.

I trust the Oura morning habit more, and that's a preference, not a trial.
Import history was messy in 2026, so check that the size you want is shipping.

3Best for people who want training load on a wrist

WHOOP 5.0

7.8

The training strap, sold as a membership, with no Amazon button here.

Best for: you already think in strain and recovery and you'll wear a wrist band to sleep.

Skip it if: you wanted a one-time gadget. WHOOP is a membership.

Pete's take

WHOOP is for the person who wants yesterday's strain next to last night's heart rate. That's a real use, and a ring you forget you're wearing is a different one. The membership is why Cost sits at the bottom of this page. I'm not printing the fee. I also found Amazon listings that weren't sold by WHOOP, so there's no button. Buy it from WHOOP if the strap is the point. I didn't train in a 5.0 for this page.

More pros and cons

Training load is the most developed of the three, if strain is the question you actually ask.
Overnight heart rate is on the strap, so the Wegovy trend is still there.
A wrist band suits people who hate rings and will still sleep in it.

You're buying a membership, so it isn't a one-time device.
I won't link an Amazon offer that isn't sold by WHOOP.

The Wegovy label says resting heart rate can rise and should be monitored. We compared the three best-known screenless trackers on what they measure overnight.

The other half is what they cost over two years, and which one fits your wrist, finger and budget.

What the label says about heart rate

"I am worried about a significant raised heart rate." Posts like that one from r/Retatrutide come up often in GLP-1 forums. The Wegovy label reports mean increases in resting heart rate of 1 to 4 beats per minute compared with placebo in the adult weight-reduction trials, and tells prescribers to monitor heart rate at regular intervals. It asks patients to report palpitations or a racing heartbeat at rest (Wegovy prescribing information, section 5.9).

A tracker gives you a nightly resting heart rate trend, so you have numbers to bring to an appointment. It does not tell you why your heart rate changed.

How to read your resting heart rate trend

Wear the tracker every night for two weeks to set your baseline.
Look at the 7-day and 30-day average, not single nights. Alcohol, a late meal, illness and hard training all raise it.
Note the date you start or change any medicine in the app's notes.
If your average stays several beats above your baseline, or you feel your heart racing at rest, contact your prescriber.

Common questions

Does Ozempic or Wegovy raise resting heart rate?

The Wegovy label reports mean increases of 1 to 4 beats per minute compared with placebo in adult weight-reduction trials, and says heart rate should be monitored. Tell your prescriber about palpitations or a racing heartbeat at rest.

Which tracker is best for resting heart rate on a GLP-1?

All three report overnight resting heart rate. Oura Ring 4 is the easiest start at plus a month; Ultrahuman Ring Pro has no subscription; WHOOP suits wrist wearers.

Is Oura or Ultrahuman cheaper?

Oura charges a membership after the first month. Ultrahuman Ring Pro does not. I left the dollar figures off this page. Read each brand's membership terms before you buy.

Can I buy an Ultrahuman ring in the US?

The Ring Pro, yes. US customs cleared its redesign in March 2026, and it is sold on Amazon by Ultrahuman US. The older Ring Air remains blocked from US import.

Does WHOOP need a subscription?

Yes. WHOOP sells the band with a membership. I am not listing the dollar amounts here. The plans are on whoop.com, and I do not have a confirmed Amazon button for WHOOP.

Can a smart ring detect a heart problem?

These trackers are wellness devices and are not built to diagnose heart rhythm problems. If something feels wrong, contact your prescriber.

If I could only buy one

If I could only buy one, it's the Oura Ring 4, after a sizing kit. The membership is the gripe. The morning heart rate is the reason.

Best for most people: Oura Ring 4

Sources, methodology, and changes

Methodology. We read the Wegovy prescribing information (section 5.9 and patient counseling), the Amazon US listings for each tracker on October 12, 2026 from a New York delivery address, WHOOP's membership pages, and news coverage of Ultrahuman's US import status. We did not wear or test any tracker. Feature lists come from the listings and brand pages.
