I highly recommend this iPhone apps - pillboxie. Download it from appstore while it's free. :)

Official Description: “Pillboxie is the easy way to remember your meds. Other med reminder apps are either too complicated or just downright boring. Pillboxie is easy because it lets you *visually* manage your meds. Scheduling a reminder is as easy as dropping a pill into a pillbox.”
