Whoop members get a fresh VO2 max estimate once a week, usually on a Tuesday. A patent filing reported by Wareable on November 3 suggests the company would like that number to show up every single day. It is a small-sounding change with a surprisingly big engineering puzzle behind it, because a daily score means Whoop has to estimate fitness on days when you did nothing but sleep and sit at a desk.
Before anyone starts hunting for a new app update, one thing needs saying up front. This is a patent, not a product. Whoop declined to comment on the report, and its own support pages still describe the weekly cadence. So this story is less “new feature is here” and more “here is where one of the most popular wearables could be heading, and why it matters.”
Quick answer
A Whoop patent describes producing a VO2 max estimate every day by switching between three data modes: passive (sleep and heart rate), active (a GPS-tracked run) and lab-calibrated. Today Whoop updates VO2 max weekly and claims accuracy within 3.3 to 3.7 mL/kg/min of a lab test. Nothing has shipped, and a patent does not guarantee a launch.
How Whoop Estimates VO2 Max Right Now
Whoop added VO2 max estimates in March 2025, and the current system already uses more than one source. Per Whoop’s own description, it works in three tiers. The base layer is passive and leans on your resting heart rate, sleep and general activity data. The second layer adds GPS: for outdoor runs logged in the last 90 days, pace from the GPS signal and your heart rate response to that pace feed into the estimate. The third layer is ground truth, where you can enter a VO2 max value from a lab test.
There are a few ground rules worth knowing. You need at least 14 recoveries in the last 21 days before Whoop will give you a number. GPS runs of 15 minutes or longer help the estimate but are not required. And Whoop says it does not currently pull in GPS data from outside sources like Strava or Apple Health for this calculation, so a run recorded on another device will not sharpen your score.
What the Patent Reportedly Describes
According to Wareable, the filing describes a method that picks between the three data modes depending on what is available and how good it is. If you have no recent workout, the passive model carries the day. If you tracked a run with GPS, the active model takes over. The idea is to always use the freshest, highest quality input instead of waiting for the weekly job to run.
Simplified from Wareable’s report on the Whoop patent. The patent is not a shipped feature.
Reports Disagree on the Lab-Test Piece
Here is where it gets messy. Wareable’s reading is that a clinical VO2 max entry would be an idle metric that does not change the estimates produced on the device. The5KRunner, which covered the same patent, says a lab result does shift the estimate if you enter it with the correct test date. Both cannot be right, and a patent describes what a company wants to protect, not necessarily how the final app behaves. If you own a Whoop and have a lab number, check what the app does with it today rather than trusting either summary.
The same caution applies to the accuracy claim. Whoop says its estimate lands within 3.3 to 3.7 mL/kg/min of a lab-measured value. That is Whoop’s number, and wrist-based estimates tend to behave best for people with steady training and decent data, and worst for people whose heart rate behaves unusually. It is a useful trend line, not a medical measurement.
| Question | Whoop today | Patent as reported |
|---|---|---|
| Update cadence | Weekly, usually Tuesday | Daily |
| Data used | Passive, GPS-augmented, lab entry | Switches between passive, active and lab-calibrated |
| GPS needed? | No, but runs of 15+ minutes help | Used when a tracked run exists |
| Eligibility | 14 recoveries in the last 21 days | Not specified in coverage |
| Status | Live feature | Patent filing, no launch announced |

Does a Daily VO2 Max Even Make Sense?
This is the fair skeptical question, and The5KRunner raised it too. VO2 max is a slow-moving number. Real fitness changes show up over weeks and months, not overnight, so a daily reading would mostly wobble around the same value. A line that jumps up and down every morning could even make people anxious about noise that means nothing.
There is still a case for it. If the daily score smooths itself and only reflects real data, it gives you a trend that reacts sooner after a hard training block, a layoff or an illness. It also fits Whoop’s broader pitch, which is built around daily readiness scores. A daily VO2 max would sit more naturally next to Recovery and Strain than a number that refreshes once a week.
What This Means for Whoop Members
- Nothing changes today. Your VO2 max still updates weekly, and no rollout has been announced.
- Log outdoor runs with GPS. If you want the best estimate now, runs of 15 minutes or more inside the last 90 days give the algorithm better inputs.
- Watch the trend, not the decimal. A change of one point in a single week is within the noise of any wrist-based estimate.
- Treat it as a guide. Wearable VO2 max is useful for direction, not for clinical decisions.

Frequently Asked Questions
Does Whoop show a daily VO2 max score now?
No. Whoop still estimates VO2 max once a week. The daily version appears only in a patent filing, and Whoop has not announced it.
How accurate is Whoop’s VO2 max?
Whoop says its estimate is within 3.3 to 3.7 mL/kg/min of a lab-measured value. That is the company’s own figure, so treat it as a best case rather than a guarantee.
Do I need GPS for a Whoop VO2 max estimate?
No. GPS-enabled runs of 15 minutes or longer improve the estimate, but the passive layer works without them, provided you have 14 recoveries in the last 21 days.
Can I enter my lab VO2 max result?
Whoop has allowed manual entry of lab values since launch. How much that entry changes your estimate is described differently by different outlets, so check the app behavior yourself.
The Bottom Line
A daily VO2 max would be a neat addition to Whoop, but it is a bet on a patent, not a promise. The more interesting part is the design: a score that quietly changes how it is calculated depending on whether you slept, ran or got tested. If Whoop can be honest in the app about which mode produced today’s number, that could make the metric far more trustworthy than a single black-box figure. Until then, keep logging your runs and judge your fitness by the trend.
