Word TrainerA spaced repetition vocabulary trainer for your own words
Memory has a simple rule: a word is easiest to keep if you review it right before you would have forgotten it. Word Trainer follows that rule for every word in your dictionary, so a few minutes a day are enough to keep hundreds of words alive.
What spaced repetition is
After you learn a word, the memory of it fades along a curve: fast at first, slower after each successful review. Review too early and you waste time on something you still know. Review too late and you learn the word all over again.
Spaced repetition keeps the reviews in the sweet spot. Each correct answer pushes the next review further away, and a wrong answer brings the word back to the start. Over time the words you know get out of your way, and your time goes where it is needed.
How Word Trainer schedules your words
Every word in your dictionary has a streak: the number of correct answers in a row. The streak decides when the word is due again. After the first correct answer it comes back in an hour, then in six hours, a day, three days, a week, and every two weeks once you know it well. A wrong answer resets the streak to zero, and the word is due again right away.
Training does not walk the list from top to bottom. Words that are due, and words you have never answered, are picked far more often than words that are not due yet, and among the due words the ones with a history of mistakes are picked more often still. Words that are not due still appear now and then as a light refresher, so nothing disappears completely.
Typed and spoken answers feed the same schedule, so you can type at your desk in the morning and answer out loud on the evening walk without losing your place.
Why it works best with your own words
A schedule is only as useful as the list it runs on. Reviewing a thousand words from a frequency list on a perfect schedule still leaves you without the word for 'receipt' the moment you need it at the counter.
Word Trainer has no pre-made decks. Your dictionary is the words from your course, your job and your street, typed in, pasted as a list or photographed from a page, with translations filled in automatically. Spaced repetition then makes sure each of them stays.
A few minutes a day, honestly
Open the app and the due words are waiting. Ten words take about two minutes. Missing a day is not a disaster: the due pile grows, but the words with a history of mistakes still come up more often, and the streaks of the words you know are not thrown away.
Statistics show your words with their right and wrong answers and collect your problem words, one tap away from training them. The Pro plan adds a streak of days, accuracy over the last seven days, a forecast of reviews for today, tomorrow and the week, a calendar of activity and a week-by-week chart, so you can see the schedule working.
Spaced repetition and cramming
Cramming works for tomorrow's test and fails for next month. Spaced repetition is slower on the first day and wins every day after: the same twenty words cost a few seconds each per week instead of an hour the night before, and they are still there when you need them in a conversation.
Frequently asked questions
How many words should I review a day?
As many as are due. In a steady routine that is usually 10 to 30 words, a few minutes. When you add a big batch of new words, the first days are busier, then the schedule spreads them out.
What happens if I skip a few days?
Nothing is lost. Due words wait for you, and among them the words with a history of mistakes come up more often. Streaks change only when you answer, so a break does not reset the words you knew.
How is this different from Anki?
Anki is a general spaced repetition engine that works on decks you build or download, card by card. Word Trainer is built around a word list: you paste words, translations are filled in, and spaced repetition, voice practice and listening come with the list, on your phone or in the browser. Typed training and saved playlists also work offline. There is nothing to configure.
Does spaced repetition work for phrases and sentences?
Yes. An entry can be a word, a phrase or a short sentence; the schedule does not care. Short phrases with the words you are learning are often the best entries.
Does it work in both directions?
Yes. You can train from your language into the one you are learning or the other way round, and switch at any time.
