Android/iOS: When you have to take medicine every day, reminders become a necessity. MediSafe allows you to keep track of every med you need to take, and allows other users to give you a nudge when you need it.
The app allows you to enter the list of medications you need to take and on what schedule. Every time you take your pills, you log the entry in the app. If your friends or family use the app, you can set it to show them when you've taken them and, more importantly, they can see when you haven't. They can give you a gentle nudge if you fall behind.
