Studying doesn't need to be all-nighters, energy drinks, and constant stress. CampfireStudy helps you learn the right way, with about 15 minutes a day. WHAT IS CAMPFIRESTUDY - Study Less, Remember More CampfireStudy lets you study for just 15 minutes a day, so you have more time for everything else: homework, sports, hanging out with friends, and just having fun (remember that?). - Turn Studying into a Game With a Friend Studying by yourself is boring. Studying with a friend and working together to keep your campfire alive is actually fun. Pair up with a friend and keep each other accountable - you both have to study each day to keep your streak up. - 3 Steps Step 1: Turn your notes into flashcards (or have AI do it for you) Step 2: Review your flashcards every day for 15 minutes Step 3: Ace your test (because you've memorized everything) NOT JUST ANOTHER STUDY APP Most study apps help you cram faster. CampfireStudy helps you never have to cram at all. Instead of studying the night before (or morning of...) the test, you study a little bit every day. It uses a method called spaced repetition flashcards. It's what medical students and language experts use to learn huge amounts of content super efficiently. Studying stops being something you do from 12-3am and becomes something you spend 15 minutes on every day. While waiting in line, between workout sets, between classes - you can review flashcards during those little pockets of time, and save the rest of the day for other things. THE SCIENCE BEHIND IT CampfireStudy uses two key scientific concepts: active recall and spaced repetition. Active recall is when your brain has to actually retrieve the information, not just absorb it (like passively rereading notes). It's one of the most effective ways to learn, and flashcards are a great way to use it. Spaced repetition is when you review information right when you're about to forget it. The better you know the information, the longer you can wait until the next review. It's built on the Ebbinghaus Forgetting Curve, a model of how quickly we forget things, which shows the best moment to review something is just before it fades. Together, these concepts combine into spaced repetition flashcards. By turning your notes into flashcards and reviewing them at the right times, you study less (a few minutes a day) and remember more. KEEP THE CAMPFIRE LIT Everyone has their own fire: their personal streak. But if a fire is a streak for one person, a campfire is a streak for two. Just like friends gather around a campfire to roast s'mores and share stories, you can pair up with a friend in CampfireStudy to create a shared streak. You both have to study every day to keep the campfire alive, which makes it a lot harder to skip a day. A LOOK AT THE APP - Create flashcards or use AI to generate them from your notes - Organize your flashcards by decks (classes) and tags (units) - The algorithm works out exactly when to review each flashcard - Use Cram Mode to study for specific tests - Pair with a friend and keep your campfire alive I'm a student myself, and I built this for other students and anyone who wants to learn more efficiently. And, of course, it's free. Happy camping! For more information, email hello@campfirestudy.com or check out @thatflashcardgirl on Instagram.

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.
