I bought this to help our 3 year old adjust to the time change while traveling in Japan. It did help him to sleep or stay in bed during night time and get up in the morning.
However, this app could be better with the following improvements:
1. Have the ability to adjust brightness of the sleeping light because it is a bit too bright.
2. Have the image work with both orientation, not just portrait.
3. Instead of setting the wake-up set as a timer, it would be more user friendly if we were able to set it in actual wake-up time.
4. It would be nice if there soft and soothing animation should the child require some entertainment while waiting to fall asleep or wake-up
