I got this app to track my medication and it's perfect! I can set up how I want to take each medicine (yes/no or quantity), see the start date and adherence in the summary view, and even track side effects and effectiveness each day then see them in a chronological list in the sunmary. And the best part is that it's not tied to some medical database! Added bonus: I can track real to-dos as well. Overall, love this app!
