Best app on my phone!


I would've given a full 5 but I can only keep track of one child on this app. I have 3 small children with Sickle Cell that I would love to utilize this app for. Am I missing something or is this feature not available. This is a great idea, a wonderful way to track yours or your family's illness sans pencil and paper.. As well as keep track of other related info. Thank you for this!
