Homework, practice, reading, exam prep — the session ends, the notes stay in the notebook, and what you still remember is hard to say. InkBrook does one thing: it turns the takeaways and questions you write down while studying into cards, then uses spaced repetition to schedule their return.

THE METHODS BEHIND IT • A goal first (goal setting): one sentence on what you want to work out, so the session has a purpose. • Takeaways and questions after: saying what you learned in your own words is the generation effect; writing down what is still unclear is metacognitive monitoring — how far your understanding goes. • Reviews spaced out (spaced repetition): the FSRS algorithm sets when each card comes back, from your own ratings.

ONE SESSION, FOUR STEPS • Before — write a goal: one sentence, or leave it blank. • During — Pomodoro focus: 15 / 20 / 25 / 30 minutes, with an eye-rest reminder at the end; ideas and questions go down on the spot. • After — note takeaways and questions: dictate them, or attach a photo of the problem. • Later — review as scheduled: answer a question and you can add it to your review plan; when it comes back is left to the app.

HOW REVIEW TIMING IS SET Each card has its own memory state. You flip it over and rate yourself "remembered" or "forgot", and FSRS sets the next review from that: "remembered" stretches the interval, "forgot" brings the card back before long. Cards you keep forgetting are singled out, so you can go at them a different way. Attach an exam and its date to a subject — school entrance exams, IGCSE, IELTS. As the date nears, review of those subjects tightens, and intervals do not run past the exam day.

ALSO INSIDE • Voice to text: say it and it's written down. • Photograph problems: snap one and quiz yourself on the original. • Knowledge wall: look back day by day through the takeaways you wrote. • Growth record: streaks, levels and badges come from real study actions; no leaderboards, only your past self. • Widgets: your streak and library card count on the Home and Lock Screen. • Data export and import: the whole database as a zip backup, and back. • Where your data goes: study content stays on your device; turn on iCloud sync and it goes to your own iCloud. Crash diagnostics are off by default — a separate checkbox on the first-launch consent page turns them on, changeable any time. Once on, they send an installation identifier, device model, OS and app version and the error stack to the developer for fixing. See the Privacy Policy.

WHO IT'S FOR Anyone who needs knowledge to last: school study and exam prep, IGCSE / A-Level / IB, graduate and professional exams, language learning, self-directed study.

From the next time you sit down at your desk: write down what you studied, and see it again on time.
