I read many reviews, but because it had been months since there was a negative review & my friends kept recommending this system, I bought the app. Huge mistake. If you just want an app to list the times at which you should do things, then this is fine for you. It has schedules laid out. However, if you want any explanation at all, dont buy the app. If you click on a feeding time, it tells you how much milk to offer. It offers zero information for solid food. One of the descriptions actually refers you to the book, which I understand also has the schedules in it. So, if you buy the book, you get the schedules anyway. If youre looking for a shortcut for the book, I dont think theres enough information in the app to give you what youre looking for. For example, nap times just say about how long a nap should be. Nothing about anything having to do with sleep training or how to get your child to adjust to the schedule.
