Show Description

Track smarter, with the Mio SLICE. It uses Mio’s Personal Activity Intelligence (PAI) system, to calculate your activity level from your heartrate instead of using steps, which don’t work for activities like cycling or yoga. PAI makes sure you get credit for all activities by turning your activity level into a score. As you go through your daily life, training days, or rest days, PAI guides you towards a healthier you by analyzing your activity level over the last 7 days, evolving with your fitness level. The easier the exercise, the fewer PAI points it's worth, encouraging you to work harder to keep your score up.

  • Optical heartrate sensors measure changes in blood volume under the skin, and work best when worn snuggly, 1 to 3 finger-widths above your wrist bone.
  • Small fits wrists 14 cm to 17.2 cm in circumference, and large fits wrists 17.2 cm to 21 cm in circumference.
  • Works with the free Mio PAI app, compatible with select smartphones: iOS 9.0 and above and Android 5.0 and above.
  • Internal memory stores activity data, synching automatically when connected to your compatible smartphone.
  • 24-7 heartrate tracking, with activity level controlling the tracking accuracy.
  • Heartrate data is broadcast via Bluetooth and ANT+
  • Smart notifications (emails, texts, alerts and more) via Bluetooth connection to a compatible smartphone (4.0 and up).
  • Rechargeable lithium-polymer batter with USB charger.
  • Water resistant to 30m (but don’t push the buttons under water).
