Moca / Smart tumbler


Coffee is a popular food for modern people, but it is recommended to drink proper amount because of caffeine. However, depending on the type and amount of coffee, the caffeine content varies. To solve this, I suggest a smart tumbler that lets you know the caffeine content of coffee ordered at a cafe and how much caffeine you have consumed per day.
