Cardiio: Heart Rate Monitor App Reviews

Using this app for four years. Reliable and consistent. Have tried other heart rate apps for comparison and always come back to this one.

Works great and also fun to use

Works as advertised. I use Runkeeper to track my workouts and this app can synch with Runkeeper. It also synchs with Strava and the Health App in my iPhone. Love it!

great app!!, very easy to use... works for me and my family...

This app is fantastic, I would get it. Its super easy to use!! Best app for your heart❣❤️❤️❤️❤️

Awesome App

Excellent says it all

Easy to use, addictive (I can take my pulse rate each 20 minutes). Highly recommend it!

Just started using it. Great. Never thought Id enjoy it this much.

Great app. I use it daily for tracking purposes when Im doing HIIT training and its pretty accurate.

It would be nice if I could use it for my wife also.

Simple keep motivation and very basic exercises ok

Paid for pro, worth the 10 bucks. Dont waste ur time or money on the other apps. And pro has no ads.

I have been using it for a week. Good accurate and useful app. I recommend it.

iPhoneで簡単に脈拍がわかり便利ですね！

Really great application. However full version could be less expensive.

Very accurate measurement
