Polar may already be preparing Loop Gen 3

Polar Flow 7.37.0 contains direct references to a Polar Loop Gen 3, alongside a Polar 360 Gen 2 and fresh connectivity details for the still-unannounced H12.

We compared the new release with version 7.36.2, and both device names are new. More importantly, they sit inside Polar’s device-recognition code rather than a stray promotional file.

A new version of the screenless tracker

The one that is more interesting is Polar Loop Gen 3. The name appears in a new device profile tied to the hardware identifiers INW6R and Polar_INW6R, while Polar’s wider device registry has also gained a matching “loop gen 3” entry.

There is a slightly odd detail in the same profile. Its marketing-name field still says “Polar Loop Gen 2”, but the code used to recognise connected models explicitly accepts “Polar Loop Gen 3”. That could mean that Polar is still tidying up internal labels before anything becomes public.

Either way, this is more than a casual mention. Device-recognition logic exists so the app can identify hardware and apply the correct behaviour, which makes the reference harder to dismiss as unused copy left in a translation file.

The timing is what gives this some bite. Polar launched the current screen-free Loop in September 2025, positioning it as a subscription-free alternative to products such as Whoop. The current model is barely a year old, so a third-generation name appearing now points to a quicker hardware cycle than many buyers might expect.

Polar 360 Gen 2 gets a cleaner profile

Polar 360 Gen 2 is the second new name, and its implementation is less muddled. A new device profile recognises “Polar 360 Gen 2”, “360 Gen 2” and the lower-case equivalent, all connected with a new INW6S hardware identifier.

The original Polar 360 appeared in the Flow app before its wider business rollout, so this is a familiar route for the product family. Polar currently describes the Polar 360 as a screen-free platform for companies that want to build health and fitness services around Polar’s sensors, software tools and data.

The H12 is starting to reveal its purpose

The same app update also moves the H12 story forward. Our earlier Polar H12 discovery found a dedicated device profile in version 7.36.2, but there was no useful information about its connectivity, battery life or sensing hardware at the time.

Version 7.37.0 adds user-facing setup text linked to that H12 profile. It says the sensor can broadcast heart rate to as many as four Bluetooth devices simultaneously, while new open and secure modes let the wearer choose whether nearby devices can pick up the signal easily.

Secure mode is described as keeping heart-rate data from being picked up by anyone, while open mode is intended to make connections easier. That sounds aimed at people who move between watches, gym equipment, training apps and cycling computers.

What the app still does not tell us

There are no Loop Gen 3 or Polar 360 Gen 2 product images in the updated onboarding package. The onboarding file itself is unchanged from version 7.36.2, with the new models appearing only in the app’s underlying device definitions and registry.

It’s important to note here – app code can arrive months before a product, survive after plans change or cover hardware that never receives a normal retail launch. So this is evidence of development rather than confirmation of upcoming availability.

It is also worth noting that the INW6R model number has not yet appeared in any of the regulatory databases we monitor. That makes a 2026 launch look less likely, with early 2027 perhaps the more realistic window.
