Science Journal is an app to let you do experiments with your Android smartphone and directly record your results. You can either use your smartphone's built-in sensors or connect it to external sensors to do all kinds of science experiments.
From the Science Journal interface you can jot down your project ideas, make predictions about what you think will happen, take notes, and collect data from several attempts. This app is basically a proper scientific diary to keep with you at all times and help complete experiments of all types.
Science Journal is a scientific research tool that should prove as useful for science students and aficionados as for anyone with a curiosity about science.
