Yum is described as 'Pal is a visual food journal. Instead of counting calories or logging macros, you snap a photo of what you eat and it becomes part of your personal Timeline of Tastes — organized by date, tagged by meal, and pinned to the place where you ate it' and is an app. There are more than 50 alternatives to Yum for a variety of platforms, including iPhone, Android, iPad, Web-based and Android Tablet apps.
