Product Information

  • Overview

    Forget fiddly chest straps and confusing devices. The MIO Alpha is a continuous heart rate monitor watch that is both easy to use and accurate, even at performance speeds.

    Comfortable wrist band

    Using patented technology from the research labs at Philips Electronics, the Alpha is totally unobtrusive and has no fiddly set-up or chest strap to slide down or chafe. Instead, you wear it on your wrist. This clever heart rate monitor has a soft, stretchable silicone wrist band that ensures a snug fit that won’t slow you down.

    Optimise your workouts

    Heart rate training is an effective tool for endurance athletes, allowing them to measure and control the intensity of their workouts. By making sure you’re always working within the correct heart rate zone, you’ll maximise your efforts and perform at your peak.

    Technologically Advanced

    Alpha is a true scientific breakthrough as it uses technology proven accurate at rest in medical use in a form that is now robust enough for sport. Light beams and an electro-optical cell 'sense' the volume of blood under your skin. Sophisticated algorithms are applied to the pulse signal so that the heart’s true rhythm can be detected, even while running at performance speeds.

    Added data

    Alpha uses Bluetooth Smart (4.0) technology to connect to compatible devices to measure speed, distance and pace.

  • Great design but not reliable for small wrists

    This watch has a lovely feel and very clear display. The strap is snugger and softer than rival models and works nicely. And the 3 This watch has a lovely feel and very clear display. The strap is snugger and softer than rival models and works nicely. And the 3 colour LED is brilliant for letting you know at a glance - even in the dark - whether you are below, in, or above your chosen heart rate zone, even giving a double flash when you are considerably outside.

    Unfortunately the heat rate measuring technology is unreliable, dropping out and taking a while to get back up/down to speed in the following situations:

    (1) Small wrists - I used the second-to-tightest possible adjustment holes, so was at the bottom end (almost) of the size range and the unit was erratic on even vigorous walks never mind jolting runs. I tried it very tight, slightly looser and on both arms, but no difference.

    (2) Any form of exercise involving wrist movement - press-ups, weightlifting etc.

    I really wanted to go with this watch as an alternative to my Bluetooth chest band, but in the end it simply wasn't reliable enough for me with my small wrists. Kudos to a great overall design with many practical strengths, but evaluate fully under the Apple 14 day return scheme to make sure it is a reliable solution for you. Position is crucial - you must wear it behind your wrist bone as per the instructions.
