Pillboxie is a simple and effective medication management app. After you add your medication (including visual shape and color), dose and time due, the app will notify you to take it. Pillboxie also keeps track of when you miss a dose in your history. You can keep track of multiple people and set special notes for each medication, i.e. take with food.
You don’t need to be on prescription medication to use Pillboxie. I’ve found that adding a specific time to take my daily vitamin has helped with my adherence.
