Napsee is a timer made for kids. When children are young, they often don’t know how to tell time, which can make nap time frustrating for them. Minutes seem like hours and hours seem like days when you are supposed to stay put for a nap. When our children were young, my wife suggested we convey nap time in a way kinds can see. Napsee. Napsee displays time countdowns visually so that children can understand how much time is left. It works great for naps, car trips, waiting for mealtime, or waiting for anything! When the timer goes off, a smiley face appears on the screen. Sometimes kids are so excited and focused on waiting for the smiley that they fall asleep. Not to worry. Napsee makes no sounds, so sleeping kids will stay asleep. While the timer is running, the screen on your device will stay on. The screen will turn off after the smiley face has appeared for a few moments. Napsee has no ads and no in-app purchases. It works great with Guided Access, so you can prevent changes from being made while the timer is running.
