You could have downloaded PillBox 2.1 for Mac from our software library for free. PillBox for Mac lies within Internet & Network Tools, more precisely RSS Tools. This free Mac app was originally developed by Alternative Visuals.
From the developer:
PillBox makes remembering to take your daily medication easier then ever with a virtual pill box for your Dashboard. This pill box functions similar to that of a real life pill box, and serves as a simple reminder if you have taken your medication or not. If you forget your medication within the hour you'll get a warning. If you miss it by an entire day an alert will appear near the widget.
