Does Ultrahuman have a subscription?
No — not for anything that matters. Core tracking is included with the ring, permanently. But "no subscription, ever" is now slightly out of date, and you deserve the precise version rather than the marketing one.

The short answer
Everything you actually bought the ring for is free forever: sleep stages, Sleep Index, HRV, resting heart rate, recovery, skin temperature, steps, and the Circadian Rhythm view. There is no paywall, no trial that expires, and no tier that switches off if you stop paying. Buy the ring, own the data.
What has changed is that Ultrahuman now sells a small number of optional paid add-ons called PowerPlugs. Three of them cost money. None of them touch core tracking. That's the whole story — but most sites still repeat "no subscription, ever", which is no longer quite true, and a few competitors have started claiming Ultrahuman "added a subscription", which is also wrong.
Why this page exists
I write this site and I use the referral programme, so I have an obvious incentive to tell you Ultrahuman is free and Oura isn't. That's exactly why the numbers below are specific and dated — you can check every one of them yourself in about two minutes. If any have drifted since 12 August 2026, the Ultrahuman page is the authority, not me.
What's free, forever
Included with the hardware on both the Ring AIR and Ring PRO, with no ongoing cost:
- Sleep — full stage detection (awake, light, deep, REM), Sleep Index score, sleep debt, timing consistency
- Recovery — HRV, resting heart rate, recovery score, temperature deviation
- Movement — steps, Movement Index, workout logging
- Circadian Rhythm — caffeine cut-off windows, wind-down nudges, light exposure timing
- Free PowerPlugs — Vitamin D tracking, Caffeine Window, Phase Alignment, Cycle & Ovulation (basic), Pregnancy Insights
- Full data history — your past data stays visible; nothing is retroactively locked
What costs extra
Three paid PowerPlugs as of August 2026. Ultrahuman attributes the pricing to licensing, regulatory approval and medical-grade reporting costs — which is a reasonable explanation for the AFib one in particular, since that's a regulated claim.
| PowerPlug | Monthly | Annual | What it adds |
|---|---|---|---|
| AFib Detection | £4.90 | £49 | Continuous heart-rhythm monitoring for atrial fibrillation, with medical-grade reporting |
| Tesla Sync | £6.90 | — | Pulls Tesla driving data into your recovery timeline |
| Cycle & Ovulation Pro | £2.99 | £29.99 | Ovulation confirmation at claimed 90%+ accuracy; a free basic version exists |
Separately, Ultrahuman offers UltrahumanX Coverage at £36 for one year or £54 for two — an accidental-damage plan sold at checkout. It's insurance, not a software subscription, but it shows up in the same basket so it's worth knowing what it is before you tick it.
You can switch PowerPlugs between monthly and annual, or cancel them, from inside the Ultrahuman app. Prices shown are the UK store; other regions differ.
How that compares to Oura
This is the comparison most people are really making, so here it is without spin.
| Ultrahuman | Oura Ring 4 | |
|---|---|---|
| Core sleep & recovery data | Free forever | Requires membership |
| Membership cost | £0 | $5.99/mo or $69.99/yr |
| Included free period | N/A — always free | 12 months with a new Ring 4 |
| Cost over 3 years | £0 | ~$140 after the free year |
| Optional paid add-ons | 3 PowerPlugs | Bundled into membership |
| What happens if you stop paying | Nothing — nothing to stop | Most insights become unavailable |
The fair reading: if you want only core tracking, Ultrahuman genuinely costs you nothing after the hardware and Oura costs about $140 over three years. If you specifically want AFib detection, the gap narrows a lot — Ultrahuman would charge you £49/year for it where Oura folds comparable features into its membership. For most buyers, core tracking is the whole point, and Ultrahuman wins clearly.
One nuance in Oura's favour that affiliate pages rarely mention: the first 12 months are included with a new Ring 4, so the cost difference doesn't start until year two.
Is "no subscription, ever" a lie?
No, but it's imprecise, and I'd rather say so than repeat it. Ultrahuman has never charged for core tracking and still doesn't. The paid PowerPlugs are genuinely optional modules bolted on beside the core product, not a paywall moved over it. If you buy a Ring AIR or Ring PRO tomorrow and never open the PowerPlugs tab, you will never pay Ultrahuman another penny.
The claim I'd defend is: "Ultrahuman charges no subscription for core tracking, and sells three optional paid add-ons." That's what this site says now, including in the Ring AIR review and the AIR vs PRO comparison.
