Learning a language? Review lessons, notes, and your own materials on a schedule. RepeatFlow is a spaced repetition system where the Material is at the center, not the card. A lesson, article, PDF, video, study note, or even a paper textbook — learn where it works for you, and the app reminds you when it is time to come back. MATERIALS AND TAGS In RepeatFlow, the main unit is a Material. Every Material has a unique tag. Write the tag in your notes, PDF, notebook, or textbook, and you will always know what to return to and when. If it is easier to keep everything in one place, add the Material directly in the app: a link, a short note, or cards. A Material can be: • a lesson or course; • an article, PDF, or website; • a video or lecture; • study notes or a note; • a set of cards; • paper material marked with a tag. In practice, anything can become a Material: if it has a tag or you can add a link, RepeatFlow helps you come back to it on time. After you start a Material, the app builds a Review schedule from the Repeat Plan you choose. SPACED REPETITION IN CONTEXT You return to a Material by schedule, not at random — after a day, a week, a month. This helps you keep what you have learned and gradually strengthen knowledge over time. Unlike classic flashcards, RepeatFlow does not box you in: you learn in your own context. The habit of marking and organizing materials also helps keep learning orderly and more intentional. CALENDAR AND LOAD CONTROL Calendar shows not only today's Reviews, but also future load: when Materials were started, which Reviews are already done, and which are still ahead. When you set a Daily Limit, Planner helps choose safe days to start new Materials so you do not overload yourself in advance. FOCUS AND RECOVERY Focus brings today's and overdue Reviews together in one place so you immediately know what needs to be done. If a large backlog builds up, Recovery helps you return to the schedule gradually — without stress and without the feeling that everything is broken. WHAT ELSE IS IN REPEATFLOW • widgets; • passwordless sign-in with an email code; • sync across devices; • local daily reminders; • JSON data export; • analytics and diagnostics consent controls; • learning data and account deletion; • in-app support links. WHO IT IS FOR RepeatFlow is useful if you: • are learning a language and want to return to lessons, not only separate words; • are taking a course and do not want to forget what you have already covered; • are preparing for an exam with study notes; • keep notes with learning material and want to review them by plan. If the approach where everything has to become flashcards does not fit you, RepeatFlow gives you another way: learn in your own context, and let the app hold the system.
