An excellent potty training watch, the highlight of WobL Watch is its auto-reset repeating countdown timer with alarm; set it to vibrate and/or play an audible alarm reminding your child to take a potty break at regular intervals throughout the day. Set the start time and stop time (example: from 8 a.m. to 7 p.m.) and reminder interval (every two hours). The vibration and/or audible alert will automatically signal that it's time to go to the bathroom, take a walk break, test blood sugar, drink water, or whatever reminders are needed. Eight independent alarms are easy to program and great for unique daily or weekly reminders.
