In addition to tracking activity, the Ace 2 tracks sleep habits during the night. There's even bedtime reminders and silent alarms to help with time management. During the day, kids can receive notifications from their smartphones, so they can stay in touch with friends and be accessible to you. The Ace 2 does all of this and more, but always keeps you in control with a full set of parental controls. With up to 5 days of battery life and 50m swimproof water resistance, the Ace 2 can be an all-day cool companion for your kids and a helpful assistant to you.
