The Boyfriend Log is a new app that let’s you track your relationship moods over a long period of time. The data driven love tester was an app created to track possible fluctuations or patterns in a relationship. You must simply input your mood of the relationship daily with choices varying from happy, romantic, sad, angry or flat. Each emotion is color coordinated so you can track the relationship on a wider scale at a glance. Seeing a larger number of blues, for example could signify that the relationship facilitates more flat days than anything else, giving the user the opportunity to choose whether this person is the one, or one that’s got to go. The app also lets its users make various relationship profiles, allowing them to date more than one guy or gal at a time and view all of their patterns to compare. The app has a lock on it- just like a real diary- except this lock is just the standard “four digit pin.” This app can be accessed through android and iOS phones.
