But since comfort isn't the only factor contributing to a good night's sleep, the SleepIQ app can also be used to keep track of habits and activities before bedtime as well. This allows kids to see the effects that things like sports, or their diet, have on their sleep patterns. And if it's an adverse effect, like eating mountains of candy before they try and fall asleep, the app will show how they toss and turn instead of actually drifting off.
