I'm really surprised this isn't here!! Please please add a Medication Tracker. I bet that it would be one of the first types of trackers that people start using. There are important, invaluable pieces of information that it could help people track: 1) side affects / reaction -- this is HUGE, especially when you are starting out a new drug, especially if it is for something chronic; 2) Date / Time; 3) other notes or observation (example, if you ate with it, etc)
