Every chapter of your life needs its own way of learning — your hobbies, your career, school, the things you must remember, and the things you simply want to. HOW MEMSURF ADAPTS TO YOU Every quiz and lesson adapts — to the type of content you're studying, how you're actually performing, and the learning goal you've set. Review timing adjusts automatically. No two study sessions look the same, because no two people (or days) are the same. THE LEARNING LADDER Real learning isn't one pass through a deck. MemSurf moves you through four stages — Expose, Differentiate, Recall, Apply. That means: see the new information, tell it apart, recall it cold, then use it in a practical way. PICK YOUR GOAL Different situations need different learning modes and scheduling: - Keep Fresh — gentle upkeep so you never fully forget - Sprint Mode — fast memorization when time is short - Deadline Mode — build toward a specific date, like an exam, a date or a big presentation - Occasional Review — light touches, no pressure SEE YOUR GAPS. WATCH YOUR KNOWLEDGE TREE GROW. MemSurf identifies your knowledge gaps, tracks them over time, and recommends exactly what to review next. As each gap disappears, your knowledge tree grows and you become a better, more knowledgeable version of yourself. LESS FRICTION THAN ANKI. MORE STRUCTURE THAN QUIZLET. No deck design, no card templates, no manual spaced-repetition math. Send in what you want to learn — a PDF, an online article, a voicenote, a screenshot — and MemSurf builds the lesson and the review schedule for you. BUILT TO OUTLAST SCHOOL Students graduate. Curiosity doesn't. MemSurf is for lifelong learners, professionals keeping skills sharp, parents who want to stay close to what their kids are learning — and yes, students too, because every student eventually becomes one of the other three. The habit you build now is the one you'll still have in ten years. Send it in. Show up daily. We take care of the rest.

Studying alone is why you stop. Study Tracker turns it into a duel with a friend. Start the timer when you sit down. It keeps counting if you lock your phone, close the app or restart it, and a Live Activity shows the time on your Lock Screen and in the Dynamic Island. Forgot to start it? Add the session by hand. Challenge anyone on your friends list. A duel runs for seven days from the day they accept. You get a point for every day you study more than they do, and three more for winning the week. The sessions you already track count automatically. See where your time actually goes: hours per day, a breakdown by subject, a daily goal and a streak that only counts the days you hit it. You can lay a friend’s numbers over your own charts to see the gap. Comment on each other’s sessions, see when a friend is studying right now, and get a notification when they log time or reply to you. Track each subject separately and choose from eight accent colours. The app icon changes to match. Your account works on both the iPhone app and the web app, with the same data on each. You decide whether your progress is private, visible to friends or public. You can report or block anyone, and delete your account and all its data from inside the app. Free. No ads. No tracking.
