Learn words
that actually
stick.
Build vocabulary decks in any language, study with keyboard or swipes, and watch your streak grow. No subscriptions, no nagging — just one payment of $2.50.
Too great or extreme to be expressed in words.
"an ineffable sense of joy"
You studied 0/4
That's the whole loop. Now imagine doing it with your own 4,000 words.
Everything you need.
Nothing you don't.
Decks you actually want
Build colour-coded decks for any language pair — Ukrainian, English, Spanish, Japanese, whatever. Group by topic, exam, or whatever fits your brain.
Keyboard-first study
Space to reveal. ← to repeat, → if you got it. Swipe on mobile. Study faster than you can think.
Paste & parse imports
Drop in raw lines or a CSV — tabs, dashes, semicolons, pipes, even multiple spaces. Flashcards detects the delimiter and turns it into cards in one click.
Stats that mean something
Streaks that change color at 5 and 10 days, a 1–10 difficulty profile per word, and 14-day activity for reviews and sessions.
Share a deck with friends
Send a deck via a single link. They open it, accept the share, and study it like their own. Great for study buddies and small classes.
Short focused sessions
Study a whole deck or only the cards you marked Again last session. Five focused minutes counts more than thirty distracted ones.
Three steps,
then habit.
One price. One time.
Pay once. Use Flashcards forever. That's the whole deal.
Small product, big on principles.
No subscription, no email nags, no streak guilt. You pay $2.50 once and the app just stays out of your way until you open it.
Paste a list from a notebook, a spreadsheet, or a chat. The parser figures out the delimiter and builds the deck — no template, no setup.
Study with the keyboard on a laptop or with swipes on your phone. Repeat the hard ones, mark the easy ones, and the difficulty profile does the rest.
