Flashcards, rebuilt around context
A word is more than its translation.
NuanceDeck teaches vocabulary through real sentences. Every card shows a word doing its job in context: its stress, its grammar, its register. FSRS, the state of the art in spaced repetition, makes it stick; not another homemade scheduler.

Not another flashcard app
Most vocabulary apps go wide: one translation-pair format, cloned across dozens of languages, with none of the knowledge a word actually needs to be usable. NuanceDeck goes deep instead.
The flashcard is the core module
Every card teaches one sense with at least two example sentences, and they are fully interactive: tap any word for its meaning, see its stressed vowel, read its grammatical role under the phrase. Nothing on the card is static.
Each language ships its own grammar
A Russian word is not usable without its stress, its aspect partner, its case government and its register, so the Russian cards carry all of it. When French arrives, its cards will carry gender, conjugation and register instead. The card adapts to the language, never the other way around.
A module per difficulty
Where a language is hard, it gets a dedicated drill, not a generic quiz. Russian ships five: flashcards, conjugation, aspect, cases and verbs of motion. Every module reuses your deck, so practice lands on the words you are learning.
Built for the intermediate plateau
Most apps serve beginners and abandon everyone past A2. NuanceDeck's dictionary is deep on purpose: its vocabulary is built from the official CEFR level lists crossed with real word-frequency data, all the way to C1, so there is no wall to hit.
The sentence is the lesson
A card is not a translation pair. It is a word caught in the act.
specimen: one sentence, three grammars
Annotated, word by word
Every word in an example carries its own stress mark and its grammatical role. Case and aspect appear as small braces under the phrase, so the grammar is visible right where it happens.
One card, one meaning
Words with several senses get one card per sense, each with its own gloss and its own examples. You review the meanings separately, because that is how you meet them.
Review that sticks
Answer by writing the word, picking it among lookalikes, or flipping the card. Spaced repetition brings each sense back right before you would forget it.
More than flashcards
Modules share the same cards and the same review engine.
Flashcards
The core loop: recall the word from its meaning and its sentence, in write, pick or flip mode.
Conjugation drills
Produce the right form inside a real sentence, then see the full conjugation table and where the stress moves.
Browse & lookup
Every word is one tap away: senses, examples, declensions and conjugations, always in context.
Listen
Every word and every sentence spoken, stress-correct, with slow playback when you need it.
→ Ask AI answers questions about any example sentence.
Spaced repetition you can steer
Under the hood runs FSRS, the algorithm behind modern SRS: each sense carries its own memory model of stability and difficulty, and reviews land exactly where they keep you at the retention you chose. Advanced under the hood, legible on the surface.
A retention target, not a fixed drill
Pick how much you want to remember (90% by default) and the schedule adapts to hit it: easy cards drift far apart, hard ones stay close.
Never a black box
Every card shows its state, its next date and why it is due. Mastered is a label, not a graveyard: mastered cards still resurface.
No lockouts, no timers
If something is due, or you simply feel like reviewing now, you review now. A backlog is served in chunks, never dumped as one stream.
Your deck, your rules
Cap new cards per day, pause during a break, mark words you already know, suspend a sense, or resurface the mastered ones on demand.
interval growth · days
Each success stretches the next interval. A miss brings the card back within minutes, then the climb restarts.
The life of a card
⚑ Missed too often? The card is flagged as a leech and gets extra attention.
Fair by design
Language apps have trained everyone to expect tricks. NuanceDeck's model is boring on purpose.
