Write it down. Keep it in mind. Memo Clock keeps everything you need to remember in one place. Notes, files, word books, flashcards and the Logbook are the Memo; the Pomodoro, focus time and your daily numbers are the Clock. Frame what to learn into a card and it comes back on the memory curve; your focus and progress sit on a home page you build yourself. Pay once: no in-app purchases, no subscription, no ads, no account. ONE LOOP: WRITE, LEARN, FOCUS, SEE YOUR PROGRESS • Write: handwritten notes, files, photos, typing or the Logbook. • Learn: frame it into a card, learn words one by one, review when it is due. • Focus: the Pomodoro and the focus timer keep your time by category. • See: what you learned, how long you focused and your streak, on your home page. NOTES: FRAME IT, AND IT IS A CARD • Write with Apple Pencil on iPad on grid, lined, dotted, blank, Cornell or graph paper. • Only Apple Pencil writes: a hand resting on the screen draws nothing and breaks no stroke. • Tap Make Card and frame what to learn. The card remembers the page it came from. • Text in handwriting and photos is recognized on your device and found by search. FILES OPEN TO READ • PDF, Word, PowerPoint and web pages: scroll, or turn page by page; slides stop one by one or run on as one strip. • Make cards while you read, the file on the left and the card on the right. Tap Edit to write on a page. LOGBOOK: ONE CELL AT A TIME • Large cells, an aside on the left and the content on the right, in Body, Example, Aside and Red, with photos. • Hold and drag to reorder; swipe to turn pages, and on past the last for a new one. PHOTO TO CARDS AND COVERED CARDS • Select text right on a photo of a textbook for the question or the answer; frame a formula. • Cover part of an answer and it is a card: tap to uncover. WORD BOOKS • CET-4, CET-6, IELTS and Academic English come with the app, with meanings, examples and translations; make your own too. • A word you forget comes back a few words later until you know it; Know passes one you know; Undo any answer. Test asks only Know or Don't Know. FLASHCARDS • Turn the card and grade it Forgot, Fuzzy, Got it or Easy; each grade tells you when it comes back, further apart as you know it better. • Write It Out, Self-Test, or review one deck. Formulas are typeset as math, even as you type. THE CLOCK • Pomodoro and focus timer, by category and in full screen; white noise on a radio, record player, cassette or music box. • More than twenty kinds of statistics: heat map, check-in calendar, accuracy, focus time and more. TODAY AND THE DESK • Build your study home page from dozens of widgets: drag to move, drag a corner to resize, change the paper. Pin decks, notebooks, word books and logbooks to it. • On the Desk, Line Up sets everything in a grid you arrange by holding and dragging; on iPad, Free lets you put things anywhere. HOME SCREEN WIDGETS • Next Card asks the card due first; A Line keeps a line you wrote in sight; Photo to cards, Today's Reviews, Focus and more. IPAD AND IPHONE • Write and read on iPad, review on iPhone; everything syncs through your own iCloud. • Import Anki decks (.apkg) with your review history; share cards with classmates as a file.
