The Boyfriend App. Allows Users To Track How They Feel In Their Relationships. Waheeda May 16, 2014 Uncategorized There is this amazing new app. called The Boyfriend Log, which allows users to track how they feel in their relationship on a day-to-day basis. Linda Sivertsen, author of Generation Green and Lives Charmed, developed the app. after reflecting on her own relationship experiences. She wants the app. to empower women. I have to say that the concept is quite fascinating, each day the user keeps a log of how they are feeling in their relationship and all journal entries are color coded to make it easy to see how happy the user is over a period of time. The app allows you to track multiple relationships, making it user-friendly for anyone involved in more than one situation. It also allows the option to track friendships alongside romantic relationships. The Girlfriend Log, will be available later this month.
