Stuudy is a study planning app that clearly tells you what to do today simply by setting the page range and deadline for your textbooks or study materials. Once you register the page range and deadline for a textbook, Stuudy automatically calculates the pages you should work on today. Just follow the pages shown and record your progress to keep studying in a planned and manageable way. Even if you could not study as planned on a certain day, that is okay.
