BounceIt is an iOS app that automatically tracks and visually records the path of moving objects in real time, unlike other video recording technology. According to user testing results, it effectively detects and tracks objects with an overall rating of 4.5 out of 5 for importance and 4.4 out of 5 for satisfaction. Feedback indicated users found the tracking "really cool" and enjoyed drawing with moving objects. However, the app was sometimes slow to detect objects and lacked features to engage kids more, such as customizing line properties or plotting data.
