Moody or Not is a mood counter that counts people moods from different sources. You’re able to choose your mood from a list of 4 options starting with “very bad” and ending at “very good”. Each of these votes have a value, which means that being in a bad mood results in a low percentage value and vice versa. These “mood votes” are all sumed together resulting a total mood percentage which translates to stats you see in this app.
