Meet “Bubble”, a graphic application that allows you to track your index finger in relation to the smartphone screen for the benefit of actions that require more than one finger, such as zooming and rotating. This concept can be used for many on-the-go situations that require the use of one hand only such as holding a suitcase, eating, taking a selfie while zooming, etc.
