Science Journal is a tool for doing science with your smartphone. You can use the sensors in your phone or connect to external sensors to conduct experiments on the world around you. Organize your ideas into projects, make predictions, take notes and collect data in multiple trials, then annotate and explore your results. It's the lab notebook you always have with you.
