Every feature, in one place.
Most apps stop at a scheduler. Recka pairs a modern one with a study coach that tells you what to work on, catches bad cards, and keeps you from falling behind. All free, all in your browser.
A scheduler you can trust
The part every flashcard app has, done properly. Recka runs a modern FSRS scheduler that models each card’s own forgetting curve and surfaces things right before you’d lose them.
Modern FSRS scheduler
The current state-of-the-art spaced-repetition algorithm, not decades-old SM-2. It predicts when each card is about to slip and schedules it then. Fewer reviews for the same recall.
Exam Sprint, per deck
Set an exam date on a deck and Recka tightens every interval so each card gets several reps before the day, then studies weakest-first. Turn it off and normal scheduling resumes.
Know exactly where you stand
The scheduler tells you what’s due. This is everything Recka does with what it learns about you, the parts most apps leave out.
A queue that knows your exam
Weak, high-yield cards you’ll actually be tested on rise to the top; anything that wouldn’t come due until after the exam drops down. Not just what’s due, but what matters most, right now.
An honest readiness score
One 0-100 number per exam, built from how much you’ve covered, how well you’re recalling it, and how many topics are still weak. It tells you whether you’re on track, or kidding yourself.
Weak topics, not just due cards
Every topic gets a mastery score separate from what’s due, so a topic you “finished” can still surface as weak. Recka ranks them weakest-and-most-important first.
Recall vs. actually applying it
Log the practice questions you get wrong and Recka catches the gap most tools miss: topics you can recall on a flashcard but keep failing when you have to use them.
A forecast that stops you drowning
See how many reviews land each day this week, plus a recommended new-card limit so you never bury next week’s self. Already over capacity? Recka tells you to ease off.
Rescue mode for falling behind
Instead of a wall of 400 overdue cards, tell Recka how much time you’ve got. It builds a realistic catch-up session, or spreads the backlog across a few days, so you’re never underwater.
Write better cards, keep fewer leeches
Good scheduling can’t save a bad card. Recka helps you write ones that actually stick, and flags the ones quietly eating your time.
Card-quality coach
As you write, Recka flags cards built to fail you: a prompt cramming five facts, a cloze hiding three deletions, or an answer that’s really a list. Then it watches your history for leeches. Every flag is a suggestion, never an auto-edit.
Rich, distraction-free editor
A clean WYSIWYG editor with bold, italic, colour, highlight and lists. No visible markup to fight with, and formatting that behaves the way you expect between cards.
Cloze without the code
Make cloze deletions inline with a keystroke, no typing {{c1::…}} by hand. Basic, reverse and cloze cards all live in the same editor.
Markdown & images
Write with lightweight markdown and drop images straight into a card. Everything renders the same in the editor and in review.
Fast, organised, out of your way
Decks & folders, your way
Organise decks into nested folders, and give any deck or folder a name-based monogram, an emoji, or your own cover image, so your library is scannable at a glance.
Paste cards from Quizlet
Paste a list from Quizlet’s export, a spreadsheet, or any “question, answer” lines, and Recka turns it into a deck in seconds.
Keyboard-first review
Rate, flip and move through a session entirely from the keyboard. Recka is built for people who study fast and often.
Instant undo
Misrated a card? Undo it immediately. No dialog, no digging through history. One keystroke and it’s back.
Stats & review heatmap
A calm dashboard shows your streak, workload and progress over time, so momentum is visible instead of guessed at.
Light, dark & system
A warm, considered theme in light or dark, or set it to follow your system automatically. Recka stays easy on the eyes for long sessions.
Nothing to install. It just opens.
Recka is a website. Open it on any laptop, tablet or phone and start studying.
Saved on your device
Your cards are stored in your browser as you study, and the scheduler runs right there too, so reviewing stays quick even on a patchy connection.
Sync and backup with a free account
Sign in and your library syncs quietly in the background and stays backed up, so you can move between devices without missing a beat.
Always the latest version
New features and fixes arrive the moment they ship. There is nothing to update: open Recka and you are on the newest version.
See it on your own decks.
Open Recka, paste or build your first deck, and let the scheduler and coach do the hard part. Free, in your browser.
