The first wearable to translate heart rate data into Personal Activity Intelligence

Simply tracking your number of steps isn't enough to ensure a healthy lifestyle. With this in mind, Mio has developed a whole new way to look at your activity level. Combining your heart rate data along with all of your movements, PAI will give you a personalized PAI score so you can easily recognize how active you have been.

This personalized formula takes into account your current fitness level to give you a PAI score that works just for you. Your job is to simply keep your score above 100 to ensure you are always moving in the right direction.

Instead of tracking a daily goal, PAI keeps a rolling 7-day goal. This allows you to make up for a less productive day by going harder on another day. Forget tracking steps and steps alone, with PAI you will be tracking everything from yoga to cycling. Now everything counts.


  • Personal Activity Intelligence (PAI) tracks your body's response to physical activity and gives you personalized, actionable feedback to help you optimize your health
  • Provides accurate, continuous, all-day heart rate monitoring, which also translates into your PAI score based on your personal profile data
  • Tracks steps, distance, calories burned, sleep patterns and resting heart rate; remembers up to 1 week of activity
  • ANT+ and Bluetooth wirelessly connect to the Mio PAI app and other popular fitness apps and enable smartphone notifications
  • Rechargeable Lithium polymer battery provides up to 5 days of battery life, depending on settings and usage levels
  • Compatible with select smartphones: iOS 9.0 and above (iPhone 5S or newer) and Android 5.0 and above (Google Nexus 5, 5x, 6, 6p; Samsung Galaxy S5, S6, S7, Note 5)
  • Water-resistant design withstands submersion to 30m
  • Small size fits wrists measuring 5.5 - 6.75 in.
  • Large size fits wrists measuring 6.75 - 8.25 in.
