StudyO is a study planner that starts with you, not a template. Most study advice assumes everyone works the same way. You don't. Some people start early and some start the night before. Some need structure and some need room. StudyO figures out which kind of studier you are, then builds every plan around it. FIND YOUR STUDY PROFILE Answer 10 quick questions about how you really work. StudyO scores you across six dimensions: getting started, structure, thinking out loud, self-checking, depth versus pace, and what drives you. You get one of more than 100 study profiles, with your superpower, what to watch out for, and the one change that will help you most. TURN ANY ASSIGNMENT INTO A PLAN Add an assignment, pick the subject, when it is due, how hard the class is, and how you are feeling about it. StudyO builds a step-by-step plan matched to your profile. Two people with the same assignment get different plans, because they need different ones. CHECK THINGS OFF, EARN XP Every step you finish earns points and moves your progress bar. Finish the whole plan and celebrate. DAILY CHECK-IN Tell StudyO how you are feeling today, whether that is tired, stressed, or focused, and get a nudge on where to start. STUDY REMINDERS Turn on a daily reminder at the time that works for you. Each one tells you what is next on your list and how many steps are left. PRIVATE BY DESIGN No account, no sign-up, no ads. Everything you enter stays on your phone, and StudyO works without an internet connection. Built by students, for students.
