Camera Stopwatch Lite is a free Android app developed by Vieri Technologies that allows you to measure the elapsed time of any video you have captured. It is a versatile tool that can be used to measure the period of a pendulum, the velocity of a sprinter, or the velocity of a ball in sports like tennis, soccer, and baseball. You just need to load the video and specify the starting and ending frames to get the analysis result. The app also offers a navigation bar and toolbar to make frame selection easy and accurate. Plus, you can save and share the analysis result with others. With 64-bit support, the app offers faster navigation and a seamless user experience.
