Whoop Meridian dresses up the tracker and complicates charging

Whoop has spent years building a company around a single behavioural demand: leave the thing on. The app nags you with an "off body" notification the moment the sensor loses skin contact, and the Whoop MG ships with a battery puck that slides over the tracker so you can top it up mid-wear. On Thursday the company launched a $149 accessory that breaks that rule.

The Meridian is a Milanese-style mesh band for the Whoop 5.0 and Whoop MG, made from titanium, with the gold, rose gold and matte black finishes achieved through PVD coating. There is a magnetic clasp with continuous adjustment, a tapered silhouette and the company's "W" sitting on top. It costs $149 in the US, £119 in the UK, €129 in Europe and AU$229 in Australia, and it went on sale the day it was announced. The 5.0 and MG take different versions at the same price.

Whoop is not claiming the metal changes what the sensor sees. TechRadar reported that Meridian "keeps the same sensor array and tracking accuracy as the standard band," and the company framed the product to the site as a fix for a behavioural problem rather than a technical one: "Meridian is designed to solve one of the biggest gaps in health wearables: the fact that most people take theirs off exactly when continuous tracking matters (sleep quality outside routine, recovery on off days, stress during social events)."

That is a reasonable read of how people actually live with these things. The Gadgeteer put the scenario plainly — a day that starts with a workout, runs through the office and ends at dinner — and noted that your physiology does not pause when you change clothes, but your willingness to wear a neon fabric strap might. The site also pointed out the limit of the argument: there is no independent data showing Meridian owners generate better metrics, so the value depends entirely on whether you were the sort of person who left the tracker on the nightstand in the first place.

Gizmodo's Ian Carlos Campbell made the design case for Milanese specifically. The style is woven from individual metal wires, which makes it more flexible than a link bracelet while reading as at least as premium. Because Whoop has no screen to disguise, the mesh does most of the visual work on its own. Wearables have chased this look before, from the Fitbit Luxe to the Hermès editions of the Apple Watch.

Here is the part the launch coverage kept circling. Meridian is not compatible with on-body charging, a limitation Whoop states on its own product page. Notebookcheck explained why: the inductive charger cannot push power through a metal band. To charge, you take the Meridian off and swap to another strap, which means owning a second band and physically interrupting the continuous wear the product exists to protect.

Ivan Jovin at Gadgets & Wearables weighed how much that actually stings. With the Whoop 5.0 running around 14 days between charges, the swap is not a daily chore. But being able to charge while still wearing the tracker is one of the genuinely good pieces of Whoop hardware design, and Meridian removes it. His summary was blunt: the band solves an obvious Whoop problem in that the tracker never looked smart, and makes charging more awkward in the process.

The price is where the comparisons get uncomfortable. Whoop hardware only works while you are paying. The cheapest membership runs $199 a year, with the most advanced tier at $359, and Gizmodo noted the hardware simply stops working once payments stop. Whoop does offer routes to soften the entry cost, including trade-ins against competing wearables and payment through FSA or HSA funds.

Stack a $149 strap on top of that and the band alone costs more than several complete trackers. Gizmodo lined it up directly against the $99 Fitbit Air and the $200 Garmin Cirqa, both of which run without a subscription even if they offer one. Notebookcheck made the same point about the Fitbit Air and the Amazfit Helio Strap. Reaction on social media split along those lines, according to Gadgets & Wearables: some users were relieved to finally get something that reads less like gym equipment, others went straight to the price.

One detail is worth flagging because the coverage does not agree on it. Whoop and most outlets describe Meridian as 100 percent titanium; Mashable's writeup called it waterproof stainless steel mesh. The manufacturer's own material claim is titanium.

The commercial logic sits outside the spec sheet. The Business of Fashion reported that Whoop, now valued at $10.1 billion, is using the launch to court more female customers, with a campaign shot in Paris and Milan featuring stylish working women. In the UK the company ran the band past a different audience, with Esquire pitching Virgil van Dijk's £119 Whoop as something to wear with a suit.

Read that way, Meridian is less a fitness product than a permission slip — a way to keep a subscription running through the hours a fabric strap would have ended it. If you already wear a Whoop everywhere without thinking about it, the $149 buys you nothing but a nicer wrist. If you have been quietly taking it off for dinners and weddings, the band closes a real hole in your data, right up until the battery runs down and you have to take it off anyway.
