Download Voovo, create flashcards faster than ever and (f)ace your exams! Countless studies show that active recall and spaced repetition are the two most effective learning strategies to memorize new information. Studying with digital flashcards is the easiest way to utilize these methods, however, it has always been extremely time consuming to make flashcards… NOT ANYMORE! Voovo takes the concept of study cards to another level and lets you create 150+ flashcards in under a minute! WHAT IS VOOVO? Voovo is an innovative study app for school and uni, which helps you study faster by empowering you to create flashcards in a blink of an eye. Whether you need to study medicine, understand math or memorize words in a foreign language, Voovo is the best flashcard app for you. Make a study plan, create your deck of flashcards easily and memorize everything. Voovo is the first application to use SEVERAL INNOVATIVE WAYS TO MAKE FLASHCARDS: 1. OCR Diagram cards This is the fastest way to create memory cards. This method allows you to make more than hundreds under a minute. You simply take a picture of a diagram and Voovo does all the rest: using text analyzing algorithms, we find all the relevant text on the picture, we put it into boxes, you can choose whichever you want to memorise and your flashcards are ready to be revised. 2. VOICE CARDS Creating simple, general flashcards takes forever and they can't be created simultaneously while reading your study notes. Instead of typing in the question and the answer, just use your voice and make flashcards fast: 3-5 times faster than with the regular method. 3. FILL IN THE BLANKS CARDS Instead of typing in the answer, simply choose the words you want to hide in the question. Very useful for definitions or memorizing paragraphs. You can create fill in the blanks easily: simply take a picture of the textbook, Voovo scans the text for you automatically, you choose the words you want to hide, and you are ready to go. 4. SIMPLE FLASHCARDS The very well-known question and answer combination. Add text, images to your flashcards and memorize anything you want. 5. Ai FLASHCARDS You can generate flashcards automatically from any text, no matter if typed or scanned. You can ask Voovo Ai to generate an automatic answer to the text you put in, or generate an automatic question. Even better, you can put in complete paragraphs, or definitions and Voovo Ai will generate automatic question and answer combinations for you.

Cardstack Study

Cardstack is a flashcard app for memorising things properly, languages, dates, definitions, exam material, anything you need to actually know rather than vaguely recognise. You organise cards into subjects and stacks, then study them in three escalating modes: Absorb to read through with no pressure, Practice to type your answers with mistakes forgiven, and Test to prove you know them cold. Cards you get right drop away; cards you get wrong keep coming back until they don't. Anything you master returns days or weeks later, so it stays learned. Most flashcard apps let you feel productive without learning anything. Cardstack is built so you can't do that. It won't call you finished until you actually are. HOW IT WORKS Absorb — cards flip automatically, no pressure, just read and take it in. Practice — type your answers. Three correct in a row masters a card. Typos are forgiven. Test — the strict version. Three correct, no typos forgiven. Any mistake resets the card to zero. WHY IT WORKS Most revision rewards recognition, not recall. You see an answer, think "yes, obviously," and move on having learned almost nothing, until it matters and it's gone. Cardstack is built around active recall instead: actually retrieving something from memory, not just recognising it. You can't mark yourself correct. The card decides. Once a stack is mastered, it comes back on a schedule, 3 days, then 7, then 14, then 30, so what you've learned stays learned instead of fading by morning. WHO IT'S FOR Students revising for GCSEs, A-levels or finals. Professionals studying for licensing exams. Career-changers picking up new terminology. Language learners building real vocabulary. Anyone who's ever sworn they knew something, right up until they needed it. Free to download.
