How do we create decks in FlashcardHub?
Instantly type terms, scan physical objects, or import from Anki.
Discovered by Hermann Ebbinghaus, the forgetting curve shows we lose 50% of new learning within 24 hours. FlashcardHub spaces your reviews exactly as you are about to forget.
Within 24 hours, you forget up to 50% without testing. A quick 10-second active recall session boots you right back to 100%.
We combined advanced memory tracking algorithms with rich, user-friendly deck design tools to create the ultimate free revision catalog.
Create custom cards in seconds using simple text definitions or math formulas. Build structured study decks tailored exactly to your subjects.
Scan images of physical objects or copy textbook terms. Master Spanish, German, Japanese, or any object recognition vocabulary.
Our adaptive memory scheduler calculates your personal forgetting curve and alerts you to review precisely when memory begins to fade.
Monitor your study heatmaps, card review history, active streaks, and memory retention percentages completely for free.
Synchronize unlimited cards and study sessions across iOS, Android, and web. Your progress is backed up securely to the cloud.
Fully render complex LaTeX equations, programming scripts, and code block snippets with native syntax highlighting.
Create custom flashcards to learn physical objects, terminology, or coding. Flip, rate your recall, and watch your memory interval climb.
See how students, developers, and medical professionals use our spaced repetition app to master their subjects.
“Preparing for the USMLE Step 1 was incredibly overwhelming. Traditional study notes just weren't sticking. Switching to this app was a lifesaver. The SuperMemo-2 algorithm scheduled my reviews perfectly, and I memorized over 4,000 anatomical cards in 3 months. I couldn't have passed without it!”
Medical Resident, USCSF
“I use this app daily to study systems architecture, system design patterns, and vocabulary for a new language I'm learning (Japanese). The markdown rendering works brilliantly for code snippets, and cross-syncing between my iPhone and web app is smooth as butter.”
Senior Software Engineer
“I've tried almost every vocabulary app out there, including Anki. While Anki is powerful, its interface feels ancient and is painful to use. This app gives you the raw algorithmic power of Anki wrapped in a gorgeous, modern, and engaging design that actually makes me want to study every day.”

We take pride in building the most intuitive and robust tool for active learning.

Everything you need to know about our free science-backed flashcard app and how to get started.
Yes, completely! FlashcardHub is built as an open, fully free education utility. There are no subscriptions, no locked tiers, and no ads. You have unlimited access to deck creation, sharing, active recall statistics, and our memory scheduling algorithms.
Spaced Repetition is a scientifically proven active learning technique where cards are reviewed at increasing intervals (e.g. 1 day, 4 days, 7 days, 15 days). By testing your memory precisely when you are about to forget, it locks the knowledge into long-term memory with up to 90% less study time compared to rote cramming.
FlashcardHub is highly versatile. You can create custom decks pairing translations with pictures of physical objects or scan textbook concepts. For instance, our prebuilt 'Object Recognition' deck lets you practice identifying and translating objects like apples, books, and bicycles across multiple languages simultaneously.
Yes! We support importing standard deck formats. You can import CSV, .apkg (Anki decks), or directly copy and paste Quizlet text sets, enabling you to bring all your existing materials over with one click.
Absolutely. Once you create a deck, you can generate a share link or a unique collection key. Classmates or friends can enter this key in their FlashcardHub app to instantly import your deck and start learning.
Join over 1,000,000 active students and professionals globally. Create custom flashcards, learn things, and review for free.
