Polar Verity Sense optical heart rate monitor armband for sport (ANT+ & dual Bluetooth) – waterproof HR sensor

Comfort-first design for training

Polar Verity Sense is an optical heart rate monitor that aims to get out of the way. The strap sits on your upper or lower arm so your wrist stays free, which can matter if you’re the type who hates sensors shifting under a watch or tight sleeves. It’s also described as usable under tight-fitting clothing, and there’s a swimmer-focused approach too: you can clip it into a swimming goggle strap position or keep it snug against your skin depending on the session.

On paper, the “only one button” idea is there to reduce faff. When you’re about to start a ride, run, or swim and you don’t want a fiddly setup, this kind of simplicity is genuinely appealing. Still, if you’re expecting a watch-style experience with lots of on-device controls, that’s where it may feel limited: it’s built to be worn, connected, and used alongside an app or device rather than acting like a full fitness computer.

Key takeaways for connectivity and app use

The big practical win here is connectivity. Polar Verity Sense uses Bluetooth and ANT+, and you can have two simultaneous Bluetooth connections. That matters if you train with more than one app or you want your phone and another device to both receive heart rate without constantly re-pairing.

It’s also stated to be compatible with Peloton, Zwift and other apps. The useful way to think about this is: it’s designed for people who already ride and train inside connected platforms, and want heart rate to “just show up” rather than doing manual syncing after the fact.

And there’s a useful flexibility element: you can follow heart rate in real time on a connected device/app, or record your session and transfer later to your phone. That’s handy if your phone won’t be with you for every moment of the workout.

What it’s like in real sessions (cycling, running, swimming)

For cycling or other land-based workouts, the armband approach is straightforward: slip it on, switch it on, and start. The sensor is meant to track your heart rate so you can see it through your connected setup.

For swimmers, it’s more specific. The description calls it a “swimmer’s best companion” and explains that it can clip conveniently in its swimming goggle strap against your temple. It’s positioned as automatically tracking heart rate, distance and pace in the pool. If swimming is part of your routine, this is one of those products that fits the niche properly—less “wear it somewhere random”, more “there’s a place for it on swim kit”.

Where it stands out (and where to be cautious)

Strengths you’ll notice day to day - Simple start-up with only one button, so less interruption when you’re ready to train. - Dual Bluetooth plus ANT+ support, with two simultaneous Bluetooth connections. - Swim-friendly wearing option, including a goggle strap clip against the temple. - Waterproof use is explicitly mentioned, which is reassuring if your sessions include rain, sweat, or pool time.

Limitations to keep in mind - Because the focus is on connecting to devices/apps (rather than a standalone screen experience), it may not suit you if you want heart rate displayed directly on the sensor itself. - If you only ever train without apps or dedicated ecosystems, you might find yourself less motivated—this is more “plug into your training set-up” than “use it like a standalone gadget”.

Also, note that this grey colour of the Verity Sense is exclusively available on amazon. Colour won’t affect performance, but it can matter if you’re trying to match existing kit.

Technical overview (the essentials)

This is an optical heart rate monitor armband (unisex sport) designed for training. In the box you get the sensor, armband, swimming goggle clip, charger, a washing bag, and an information note.

From a compatibility point of view, the key details you should care about are the connection types (Bluetooth and ANT+), the ability to connect two Bluetooth devices at once, and the stated compatibility with Peloton, Zwift and other apps.

Care and practicalities before you buy

A small but sensible thing to plan for is cleaning and storage. The included washing bag suggests the manufacturer expects you to remove and care for the armband/sensor setup after training, especially if you’ll sweat in it regularly. If you want the armband to keep sitting comfortably and reliably, washing discipline is part of the deal.

You’ll also want to consider how you normally use heart rate data. If you’re using connected apps in real time, the “live heart rate” option makes this a smoother experience. If you sometimes train with gaps in connectivity, the “record then transfer” route can be a better match.

Should you buy it?

It’s worth considering if you want an optical heart rate monitor that’s comfortable enough for daily training, supports Bluetooth and ANT+, and can feed heart rate into training apps (with stated support for Peloton and Zwift). It also makes sense if swimming is genuinely in your mix, because the described goggle strap/temple clip approach is clearly part of the design.

You may want to skip it if you’re looking for a standalone display-focused device, or if your workouts don’t involve apps/devices that can receive Bluetooth/ANT+ heart rate. And if you’re very sensitive to how sensors sit under your clothing, it’s worth taking the armband wearing style into account before committing—comfort is a selling point here, but it’s still something you’ll need to fit to your body and routine.
