About

Stuudy

Features
Read full description

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. Stuudy recalculates your plan and adjusts today’s study amount based on your current progress. “I want to finish this textbook before my exam.” “I don’t know how far I should study each day.” “I don’t know how to catch up after skipping a day.” Stuudy supports this kind of study management in a simple, page-based way. 【Main Features】 ・Automatically calculates today’s pages Stuudy shows the pages you should work on today based on the page range and deadline of your textbook. ・Recalculates your plan even if you fall behind If you do not progress as planned, Stuudy automatically adjusts your study plan based on the remaining pages and deadline. ・Manage pages for each study material Register the material name, start page, end page, start date, and deadline to manage multiple textbooks and workbooks together. ・Record your progress Record completed pages and check whether you are ahead of or behind your plan. ・Supports multiple study rounds You can manage not only the first round, but also second and third rounds.
