One daily session for vocabulary, genders, conjugation, grammar, listening and reading. The app works out when to bring each thing back, before you forget it.

Six cards from six modules, with real content from the app.
A card comes back for review when your chance of recalling it drops to about 90%.
Left alone for 270 days, the chance you will recall the word drops to 48%. With four reviews in that time, it never falls below 88%.
day 270
Decks from the 100 most common words up to C1. Every card has IPA, a pronunciation recording, a sentence with its translation and the article in its gender colour, and almost every one has a photo. You practise each word in several ways.
Try to recall it first, then turn the card and say: know it or don’t.
Four translations, one right. Good for the start of a new deck.
Type the word with its article. A missing accent or one typo counts as “almost right”, not wrong.
The app reads a deck aloud, card by card. For listening on the go.
Splits a word into parts you already know, each with its translation.
Shows words that are easy to mix up with the one on the card, with translations.

What the app does, and the research behind it. The numbers are from the studies, not from our app.
In the app: The FSRS-6 algorithm schedules each card so your chance of recalling it stays around 90%. Once it has enough of your answers, it fits itself to your memory.
What the research found: Spreading study out over time gives longer-lasting memory than the same study in one block. The meta-analysis covered 317 experiments.
Cepeda et al., Psychological Bulletin, 2006; Ye, Su & Cao, KDD, 2022 (the FSRS algorithm)
In the app: A card asks first and shows the answer only after you try: you flip, pick or type.
What the research found: Learners who kept recalling words from memory remembered about 80% a week later. Those who only re-studied remembered about 36%.
Karpicke & Roediger, Science, 2008; Roediger & Karpicke, Psychological Science, 2006
In the app: Almost every card in the ready-made decks has a photo that shows what the word means.
What the research found: Words that are easy to picture are remembered better than abstract ones: they are stored as a word and as an image.
Paivio, Canadian Journal of Psychology, 1991
In the app: After every answer you see the correct form. The AI assistant explains a mistake in plain English, mid-exercise.
What the research found: Feedback is among the strongest influences on achievement: an average effect of 0.79 across 12 meta-analyses (196 studies).
Hattie & Timperley, Review of Educational Research, 2007
In the app: The listening module trains you to tell apart words that differ by one sound, like dessus and dessous or rue and roue.
What the research found: Training on minimal pairs improved adults’ recognition of sounds that do not exist in their first language.
Logan, Lively & Pisoni, Journal of the Acoustical Society of America, 1991
Answer a few questions about how you actually practise, and get a map of what your week covers, what it leaves out, and what the research says that costs you.
Why is “problème” masculine? It ends in -e!
Nouns ending in -ème are usually masculine: le problème, le système, le thème.
A common exception is la crème. Words in -ème that come from Greek are almost always masculine.
Doesn't know when you forget.
Brings each card back before it slips.
Gives everyone the same exercises.
What you get wrong comes back more often. What you know, less often.
Can't tell you why.
The AI assistant explains the mistake in English, mid-exercise.
Has no sound.
Flashcards come with pronunciation you can play.
I'm a software engineer. I've been learning French for three years, since I joined a French-speaking team.
Preparing for the DELF B2, I was juggling five apps that knew nothing about each other, so I built one with a single review plan.
I built it for myself, and it turned out to work for other people too.
If, like me, you're tired of chaos in your learning — come give it a try :)
