PZENA INV is a free Android productivity app designed to help users manage their emotions in a soothing manner. The app provides a gentle interface where users can select their current mood from a variety of emotional options, such as irritability or fatigue. This selection serves as the starting point for an emotional release process that is visually represented through an interactive water glass animation.

The core feature involves shaking the phone to simulate the emptying of the water glass, paralleling the process of releasing pent-up emotions. Once the glass is empty, users are encouraged to record their feelings or thoughts, creating a moment of self-reflection and dialogue. PZENA INV offers a calming experience for those seeking an outlet for their emotional fluctuations.
