This new EASY TO USE fitness tracker from Cactus combines fitness, wellness & fashion to get you (and your kids) moving in style. With 9 in-built exercise modes to record all types of activity data (walking, swimming, running, tennis, etc) the Zest should encourage healthy exercise. With automatic wrist-based heart rate tracking, and step counting, you can monitor your fitness goals easily. Your kids, tweens or teens will love the vibration alerts that remind them to move (how healthy is that!) or the alerts for incoming calls and texts. They won't want to take it off, and that's good because it is IP67 waterproof for swimming and showers. They'll love the 4 fun screen options - simply press the screen to change the face design.
