This app is great! It's very easy - even my kids can use it!! I wish that there was an option where they could choose whether or not their parent would receive messages about them via this system as well (I know parents like knowing if we're going through something without us having have someone come knocking at our door!). If your child has had surgery recently with anesthesia-related costs involved then definitely consider using one because when/if things go wrong afterwards its really helpful so far down into aftercare time period being able figure out what bills need paid first vs second etc..
