Write it down, and remember it. Today is a home page you DIY: widgets keep today's reviews in front of you, and your notebooks, flashcards, notes and PDFs share one desk. Pay once and get everything: no in-app purchases, no subscription, no ads, no account. TODAY: DIY YOUR STUDY HOME WITH DOZENS OF WIDGETS • Long-press to edit, drag to rearrange, drag a corner to resize; small, medium and large each have their own layout and a choice of paper. • Review: what's due and how long it takes, one tap to start; the cards due next; the two weeks around today. • Focus: a Pomodoro timer that records your focus time; white noise on a radio, record player, cassette deck or music box, with rain, ocean, campfire, café and library sounds. • Tools: Countdown, Timetable, Term Progress, Checklist, Habit, Counter, Motto, Photo, Handwritten Note. • Stats: Today's Numbers, Accuracy, Answer Spread, Streak Calendar, Review Heatmap. • Illustrations: a sleeping cat, rain on the window, a desk lamp, an hourglass, a plant, a night sky, changing with your reviews and focus. • Pin a deck, a notebook or a note from your desk to Today. HOME SCREEN WIDGETS: REVIEW WITHOUT OPENING THE APP • Next Card asks you the card that's due first, right on your Home Screen; tap to see the answer. • Today's Reviews, Focus (start or pause the Pomodoro), White Noise, Countdown, New Card, and shortcuts to your decks, notebooks and notes. • Extra-large widgets on iPad; Lock Screen widgets on iPhone. HANDWRITTEN NOTEBOOKS: FRAME IT, AND IT'S A CARD • Write with Apple Pencil on grid, lined, dotted, blank, Cornell or graph paper. • Import a PDF and write right on its pages. • Tap "Make Card" and frame what you need to memorize: that part of the page becomes a flashcard. • Every card remembers where it came from: tap "Source" to go back to that page of the notebook. • Handwriting and text in photos are recognized on your device, so you can search them. NEW CARD: TYPE, WRITE OR TAKE A PHOTO • A formula bar for typing math, shown properly typeset. • Write a card by hand with Apple Pencil. • Photograph a textbook page, a handout or the board, then cover the parts to learn with memory tape. Each piece of tape is one card. REVIEW: FLIP IT. DO YOU STILL REMEMBER? • Read the question, recall, flip, then tap Forgot, Fuzzy, Got it or Easy. Each choice shows when you'll see the card again. • Forgotten cards come back before you finish; the better you know a card, the longer the gap, based on your own review history. • Write It Out: write the answer on iPad first, then compare. Self-Test: test yourself any time without changing your schedule. • Recitation Lock (turn it on in Settings): new cards wait 3 minutes before you review them. • Morning and evening reminders, and the number of cards due on the app icon. THE DESK: DECKS, NOTEBOOKS, PDFS AND NOTES, EACH IN ITS PLACE • Decks, notebooks, PDFs and notes sit on the desk as objects with their own covers and materials. On iPad, place them freely or line them up with one tap. BRING YOUR ANKI DECKS, SHARE WITH CLASSMATES • Import Anki deck packages (.apkg): text, formulas, images, cloze cards and your review progress all come along. • Turn a few cards into a file; a classmate opens it in Memo Clock to import them. IPAD AND IPHONE • iPad is the workbench: handwriting, making cards, arranging the desk. • iPhone goes with you: review a few cards in spare moments, type a card or take a photo. Notebooks and handwritten cards from your iPad are there to read. • Sign in with the same Apple ID and everything syncs through your own iCloud. PRIVACY No account, no servers, no analytics, no ads.

You study something, you know it, and a week later it's gone. Sound familiar? Forgetting isn't a willpower problem. Most of the time it comes down to two things: how you encode information, and when you review it. Engram is a flashcard app built around exactly those two things. ■ Review right before you forget FSRS, a modern spaced repetition algorithm, predicts when each card is about to slip away and brings it back just in time. You don't re-read everything every day. Fewer reviews, longer-lasting memory. ■ Practice how you remember Five encoding strategies from memory research, practiced on your actual cards: - Rephrase: put it in your own words - Self-reference: connect it to your own life - Teach: organize it as if explaining to someone - Story: link ideas into a narrative - Visualize: picture it in your head On-device AI comments on what you write. In Teach mode it becomes a short dialogue that helps you find the fuzzy spots in your understanding. ■ Memory Palace Place the things you want to remember along a familiar route, then walk it in your head. A classic mnemonic technique, practiced inside the app. ■ Brain Check Short mini-games measure traits like working memory and plot them on a radar chart. Note: the mini-games are for measuring and tracking your own memory traits. They are not claimed to improve memory overall. ■ Quick capture Make cards from photos, audio, or text. You can also sketch things by hand to remember them. ■ Private by design Your study data and all AI processing stay on your iPhone. Nothing is sent to a server, and no account is required. ■ Engram Pro Unlimited decks, memory palaces, and AI, plus iCloud sync. ¥600/month or ¥4,000/year, with a 7-day free trial on the yearly plan. Good for exam prep, language vocabulary, technical terms, names, and anything else you want to keep for the long run. Note on effectiveness: Engram does not claim to improve general memory or intelligence on its own. What it provides is practice with encoding strategies, review scheduling based on spaced repetition, and measurement of your own memory traits. ――― Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://gokigen.space/engram/privacy Subscriptions renew automatically unless turned off at least 24 hours before the end of the period.
