Sport Proof

Performance Accurate

One Measurement For Life

PAI is a revolutionary new activity metric that uses your heart rate to help you achieve optimal health. Keeping a minimum PAI score of 100 is scientifically proven to lengthen your lifespan by up to 10 years. ALPHA 2 is compatible with the Mio PAI app, which is available from the App Store and Google Play.

DISCOVER PAI

Form Meets Function

ALPHA 2 gives you an industry-leading heart rate monitor, without sacrificing comfort. Its soft, durable silicone strap ensures a snug and comfortable fit. And with no need for a heart rate chest strap, you’ll be more comfortable during workouts.

To Your Own Beat

Every Mio Performance Wearable contains our patented, award-winning Optical Heart Rate Technology. The optical sensor detects the volume of blood beneath your skin, and immediately applies a patented algorithm to measure your heart’s rhythm and display your heart rate. This world-class technology is accurate during many activities, not just running.

Mio ALPHA 2 is rated 3.9 out of 5 by 51.

Rated 5 out of 5 by Cocoa from This is a great single-purpose watch.Very accurate I got this a couple of years back. It still holds a charge forever and it's very accurate.I don't run with a phone(I hate that) and this also works in the pool.At $110 bucks now it's a nice assistant for bikers and runners who do not want those clunky strap-ons. Could use a UI enhancement where you can track interval time AND HR. Or be able to choose chrono mode vs. HR+Time. Easy to read numbers-great font choice. Could use an LED light somehow

Rated 5 out of 5 by Eben from Great product Love the MIO Alpha 2 - great product served me well over the last year.Would be fantastic if it can produce average heart rate per lap!

Rated 5 out of 5 by rangersgt from Accurate and convenient. Extremely easy to use and also very accurate. Don't listen to sf157 as he is probably a shill for Polar and has been on other sites bad mouthing different products. no doubt a chronic malcontent! The Alpha2 is a great, well designed product.

Rated 5 out of 5 by Aurel from Love the watch! I'm using the watch since more than one year and I love it. However, last week I have lost the plastic watch strap mio clip which secures the end of the strap (the one which has the MIO logo in the front - can I order a replacement part ?

Rated 5 out of 5 by edmund from Love the Mio Alpha 2 Love the Mio Alpha 2 (its actually my second Mio Alpha watch) but part of the strap has come off. The two prong press-fit tab must have released during a workout. Would love it if there was a chance of getting a new tab.

Rated 5 out of 5 by Big Al from Great product. Looked at many watch/Heart rate monitors. By far this is the best.

Rated 5 out of 5 by BadtotheBone from Large numbers that are easy to read I got mine as a present, it is comfortable and dead on accurate.

Rated 5 out of 5 by iris19 from the very best heart rate monitor i ever owned! i got this 4 months ago and i keep being amazed on how much resistanse to baniging, water, and sweat resistancee it has, it does have a few seconds delay when training at 90-100% the heart rate comes up 3-4 seconds later, not inmediately, but its so accurate and with the app on the phone i can make all kind of calculations and adjustments to my training, the watch itself its very comfy not bulky, i really love it, i even started giving them as birthdays gift to my friends lol even of they dont work out, as motivation so they do...
