Whoop vs Oura vs Bevel: which readiness score should you trust?
Whoop, Oura and Bevel all sell the same promise in different jewellery: one daily number that tells you how recovered you are. They reach it three different ways, and the number is only ever as honest as the sleep underneath it. Here is how they actually differ, and where a phone-only score fits.
Recovery wearables have quietly converged on a single idea: take a handful of overnight signals, mostly heart-rate variability, resting heart rate and sleep, and collapse them into one score you read before you decide how hard to push the day. The maths rhymes across brands. The philosophy, the form factor and what they do with your data do not.
The three, at a glance
| Device | Form | Daily score | What it reads | Cost model |
|---|---|---|---|---|
| Whoop | Screenless band | Recovery (0-100%) | HRV, resting HR, respiratory rate, sleep, strain | Subscription only |
| Oura | Smart ring | Readiness (0-100) | HRV, resting HR, body temp, sleep stages, activity | Ring + subscription |
| Bevel | Smart ring | Wellness / readiness | HRV, resting HR, sleep, stress, with an AI coach | Ring + subscription |
| Soren | iPhone only | Soren Score (0-100) | Focus, auto-detected sleep, HealthKit movement | No account, no hardware |
Pricing and exact metrics change often and vary by region and tier, so we have left numbers out. Check each maker’s site for current pricing. HRV figures below are illustrative, not measured.
What the score is actually made of
Most of a readiness score is dominated by two overnight inputs: how variable your heart rate was while you slept (higher HRV usually means a more recovered nervous system) and how long and well you slept. The rough weighting these platforms lean on looks like this:
Whoop: the coach for people who train
Whoop is a screenless band built around a daily Recovery percentage and a Strain score, aimed squarely at athletes and serious trainers. It is subscription-only, with no device to buy outright, and it shines when you genuinely periodise effort - hard days, easy days, deload weeks. If you do not train with intent, much of its depth goes unused.
Oura: the best sleep read in a ring
Oura puts a Readiness score, detailed sleep staging and body-temperature trends into a ring you forget you are wearing. Its sleep tracking is widely regarded as the most refined in the category, and the ring form factor wins on comfort and battery. You buy the ring, then pay a monthly membership for the full analysis.
Bevel: the AI-coached newcomer
Bevel is the newer smart ring leaning hard on a generative-AI coach: the same HRV, resting-heart-rate and sleep inputs, wrapped in conversational guidance that explains your numbers and suggests what to do. The promise is interpretation, not just measurement. The caution is the same as for any AI layer - a fluent explanation is not the same as a correct one, so treat the narration as a prompt to reflect, not a verdict.
Where Soren fits
Soren is not a wearable, and it is not trying to win the recovery-score race. It points the same single-number idea at a dimension the rings and bands ignore: your actual focus. It folds focus, auto-detected sleep and HealthKit movement into one daily 0-100 Soren Score, computed entirely on your iPhone.

A Soren Score one number for the mind, no ring required
- Sleep with no wearable.Soren estimates sleep duration and timing from your iPhone’s motion and writes it to Apple Health. Stages are modelled and labelled as estimates, not clinical readings.
- Focus is in the score.None of these wearables measure whether you did deep work. Soren’s composite weights focus alongside sleep and movement.
- Private by architecture. No account, no servers, no subscription to see your own numbers. Everything is computed on-device.
So which should you pick?
- Train seriously and want strain plus recovery guidance → Whoop.
- Want the best sleep read in the most comfortable form → Oura.
- Want a ring with an AI coach that talks you through it → Bevel.
- Want one private number that includes your focus, with no hardware → Soren.
One honest caveat: Soren is iOS 17+, on the App Store, while these wearables are mature, cross-platform products that have shipped for years. If you want a private daily score that finally counts your attention, that is the trade.

Screen Time is built in and fine for soft limits. But its app limits offer a one-tap escape, and it is limits, not a score. Here is where Soren is different. Read →
