"How many days left? What should I do today?" Your exam date keeps inching closer, but your pile of textbooks isn't shrinking. Manabuild is the study planner that takes the guesswork out of daily study — and puts a specific, achievable goal in front of you every single day. ■ Work backwards from your exam date Just register your exam dates and your study materials. Manabuild automatically calculates exactly how many pages, problems, or words you need to complete today — based on your deadline, your total volume, and your own pace settings. No more "I'll just do a bit today." Your daily goal is set the moment you open the app. ■ Weight your study by day of the week Busy on weekdays, free on weekends? Assign a different study weight to each day of the week, so your plan fits your real life — not the other way around. ■ Manage multiple exams in parallel Preparing for TOEIC and TOEFL at the same time? Juggling a certification exam with university finals? Manabuild lets you register multiple exam dates as separate goals, link materials to each one, and switch between them from the side menu. A single textbook can even be linked to multiple exams. ■ Set per-material deadlines Want to finish one specific workbook by the end of the month, independent of your exam date? Each material can have its own deadline, and Manabuild will calculate that material's daily volume accordingly. ■ Multi-round study with acceleration Your second pass through a problem set is usually faster than the first. Manabuild's acceleration feature automatically raises your daily target as rounds progress. Set the number of rounds you want per material, and let the app scale the volume for each stage. ■ Carryover and partial completion — plans that bend, not break Didn't finish yesterday? The unfinished portion automatically appears as today's carryover task. Missing one day no longer wrecks your entire plan. Long-press any new task to log partial completion — "I got this far today." Record your actual progress honestly, without the all-or-nothing pressure. ■ Built-in spaced repetition When you complete a study range, Manabuild automatically schedules reviews at 1-day, 3-day, 7-day, 14-day, and 30-day intervals — fully customizable. Your brain forgets on a curve; your reviews should follow that curve back up. ■ Scan and go — barcode book registration Use your camera to scan a book's ISBN barcode, and Manabuild pulls in the title and cover image automatically. Adding a new textbook takes seconds. ■ See your progress at a glance The Statistics tab shows overall completion, per-subject and sub-category progress rings, remaining days, and remaining volume. The Upcoming view displays your study schedule on a calendar, with weekends and Japanese holidays color-coded. ■ Gentle daily reminders Set a morning notification for "what you plan to do today" and an evening notification for "what's still undone." Both times are fully customizable. ■ Your data stays on your device No account required. All study data is stored locally on your phone — private by default. ■ Four languages, flexible units Japanese, English, Chinese, and Korean supported. Units (problems, pages, words) are built in — and you can add your own custom units for anything else.
