Polar has recently announced the OH1 optical heart rate sensor which has been designed to be worn on the upper or lower arm, and comes with an internal memory that can store up to 200 hours of data, and battery life of up to 12 hours. This means that you can wear the sensor on your arm, go for your workout, and sync the data back with your phone afterwards if you’d rather not carry your phone with you all day long.
Of course the OH1 will provide the wearer with real-time heart rate tracking when paired with a smartphone and used together with the Polar Beat app, but the memory storage should come in handy if you’re after a more minimalist setup. Also unlike the Polar H7 heart rate sensor, there is no need to moisten the sensor for it to start working since it essentially uses similar heart rate tracking technology found on most fitness bands and smartwatches.
If this sounds like something you might be interested in, the Polar OH1 is priced at $80 and is available for pre-order and will begin shipping in September.
