Quat turns your notes, PDFs, photos and links into flashcards that test you on them. Most study apps start after the hard part. They assume the material is already typed in, already organised, already yours. Quat starts one step earlier: pick a file, photograph a page, paste a link, or record a lecture, and Quat reads what you captured. CAPTURE, FOUR WAYS File โ€” choose a PDF, Word, PowerPoint or Excel document. Quat reads it and turns it into a note and cards. Photo โ€” point your camera at a textbook page, a whiteboard, a handout, or your own handwriting. Quat reads the text off it. Link โ€” paste a URL. Quat fetches the page, reads it, and summarises what matters. It reads the page itself rather than guessing from the address. Audio โ€” record a lecture, a seminar, or yourself talking through a topic. Quat transcribes it and pulls out what is worth remembering. EVERY CARD KNOWS WHERE IT CAME FROM Cards carry their origin โ€” DOC ยท JUL 28 ยท CARDIOLOGY. Weeks later, when a card surfaces and you cannot place it, you can find the note it came from. REVIEW THAT ENDS Spaced repetition that schedules each card for the day you are about to forget it. When the day's cards are done, the session ends and tells you so. It does not invent more work to keep you in the app. Each rating button prints what pressing it will do โ€” now, 12h, 1d, 4d โ€” before you press it. No guessing what "Good" means. AN EXAM DATE ON EACH FOLDER Give a folder an exam date and every card in it comes back once in the last 3 days before the exam, spread across those days so nothing piles up on the night before; Final review takes you through the ones you have not reviewed in those days, weakest first. Send the folder to a classmate sitting the same exam and the date can go with it; Quat asks them before using it. BUILT TO BE READ Counters, intervals and dates are set in a monospaced face with tabular figures, so they stay legible at a glance. Quat celebrates what you actually did โ€” a finished session, a level earned โ€” never the mere fact that you opened the app, and nothing is locked behind a streak. ALSO INSIDE - A tutor that answers from your recent notes and cards first and can point to the one it used - Self-scored exam mode, separate from your review schedule - Matching, speed round, quiz and a study timer - Folders, tags and search - Send a folder to a classmate in one message โ€” they open it in Quat with one Paste - Card content in 21 languages - Works offline for everything except capture, the tutor and card generation PRIVATE BY DEFAULT No account. No sign-up. Your notes and cards are stored on your device, not on a server. None of your material leaves your device unless you ask for it: a capture sends what you handed it, card generation sends the note, a tutor question sends your recent notes and cards with the conversation, and a shared deck is sealed on your device before it goes. No analytics SDK, no tracking, no advertising. Quat is for anyone preparing for something โ€” a degree, a licence, a recertification, a driving theory test, a language. SUBSCRIPTION Everything on your device โ€” reviewing, exams, games, notes, cards โ€” is free without limit. A subscription raises the monthly ceilings on the parts that call a model: capture, the tutor, and card generation. Monthly or Annual, billed through your App Store account; it renews until cancelled, which you can do at any time in your account settings.

About

Lotli

Read full description

Lotli is a sly black cat who steals your apps. To get them back, you do one short study session built from your own course notes. Finish it and your apps are open for the rest of the day. Study first. Scroll second. HOW IT WORKS - Pick the apps that eat your evenings. Lotli locks them with Apple's Screen Time. - Add your course material: scan your notes, import PDFs and photos, or paste text. - Lotli turns it into a few minutes of questions that are actually about your course. - Finish the session and your apps unlock for the rest of the day. No meters, no buying back your own afternoon. YOUR NOTES, HIS QUESTIONS Lotli reads what you give him and writes the questions: quick quizzes, match rushes, putting steps in order, fixing the mistake and labelling diagrams. Tell him your course code and university and he sketches the course before you have added a single page. A MAP OF EVERYTHING YOU KNOW Every session quietly grows a personal knowledge map. Each course becomes a map of its topics and concepts, and a pace gauge shows whether you are on track for the exam. Ranks across five fields of knowledge only ever climb. FOCUS WHEN IT MATTERS Start a focus block and everything you guard stays shut until the timer ends. One finished session buys a single quick trip out. YOU STAY IN CONTROL You choose what gets locked and when. Change or turn off the locks any time in the app or in iOS Settings. LOTLI PRO Lotli Pro is an auto-renewing subscription, yearly (with a free trial where offered) or monthly. Payment is charged to your Apple ID when you confirm the purchase, or when the free trial ends. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Manage or cancel any time in your App Store account settings.
