How Lexi works
Lexi is a notebook, not a course. You find a word, write what it means in your own words, and add the sentence you met it in. Lexi turns that into a daily task list and asks for the words back on the day you were about to lose them.
Open the app and the Today screen tells you what is waiting. Tap a collection to start, or use Random review to shuffle everything that is due across your whole library.
Frequently asked questions
How does the review schedule work?
Each collection has a review pace, which is the starting interval rather than a fixed frequency. A brand new word you answer Good comes back after that many days. Remember it again and the gap widens. Answer Forgot and it drops back to the beginning and returns before the session ends.
Every rating button shows the interval it will produce before you tap it, so nothing about the schedule is hidden.
Only Recall changed my schedule. Is that a bug?
No, that is deliberate. Recall is the only activity that decides when a word comes back. Reverse Recall and Use it prove other things about a word and count toward mastery. Flashcards, Matching and Fill the Blank are practice you can take whenever you like without disturbing anything.
Why does a word say 0 mastered when I clearly know it?
Knowing a word is more than one ability, so Lexi asks for four things before it calls a word mastered:
- You wrote its meaning from memory, in Recall.
- You produced the word from its meaning, in Reverse Recall.
- You used it in a sentence of your own, in Use it.
- It survived a three week interval.
The word screen shows all four as a checklist, so you can see exactly which one is missing.
What happens when a word becomes mastered?
It graduates. The next time you remember it, the interval jumps to at least three months instead of climbing one step at a time, so the daily pile actually shrinks as you learn. If you later forget it, it loses the long interval and has to earn it back.
What is Use it for?
Recognising a word and being able to reach for it are two different memories. Use it exercises the second one: the meaning is shown on purpose, and you write a fresh sentence using the word. Sentences you keep are saved onto the card and become new Fill the Blank material.
Lexi says a word is stuck and wants me to rewrite it. Why?
If you lose the same word three times without changing anything about it, the card is usually the problem rather than your memory. A definition that is too abstract, or too close to another word on your list, is very hard to hold on to. Lexi hands you the definition in an editor and asks you to say it more plainly. Rewriting resets the counter, and the reworded card comes back later in the same session.
Why did I not get a reminder?
Reminders come from the review schedule, not from a daily alarm. A collection set to five days nudges you roughly every five days, on the days its words actually come due, never every evening. If nothing is due, nothing arrives.
There is also one optional evening nudge for your streak in Profile, and it skips any night you have already hit your goal. If you are getting nothing at all, check that notifications are allowed for Lexi in iOS Settings.
Can I change the daily goal?
Yes, in Profile. A day counts toward your streak once you have reviewed that many words. The default is ten.
Where can I see my past days?
Tap See your history under Today's progress. It opens a month by month calendar of every day you studied, every day you fell short, and every day you skipped. Days before your first session are never counted against you.
What is the little panel on the word screen, and why does it not always appear?
If you turn on dictionary suggestions in Profile, Lexi can add a small panel with a pronunciation, another sense or two, and extra synonyms. It only appears when there is genuinely something extra to show. It stays hidden if the switch is off, if the collection's language is not covered, if the word has no entry, if you are offline, or if everything found simply repeats the definition you already wrote.
The feature is off until you turn it on, and it sends nothing but the word being looked up.
Which languages does the dictionary cover?
English, French, Spanish, German, Italian, Japanese, Korean, Russian, Portuguese, Turkish, Arabic, and Hindi. Collections in any other language, Vietnamese included, work exactly as normal but never trigger a lookup.
My voice recording is not working.
Recording needs microphone permission, which iOS asks for the first time you tap record. If you declined, switch it back on in iOS Settings, then Lexi, then Microphone. Clips are capped at ten seconds, stay on your device with the word, and can be replaced or deleted at any time.
Does Lexi work offline?
Everything except the optional dictionary panel works with no connection at all. There is no account, no login, and no server to be cut off from.
Does it sync between my iPhone and iPad?
Not yet. Your notebook lives on one device. It is included in your iCloud or computer backup, so restoring a device restores your words, but the two devices do not talk to each other.
Can I export my words?
Not yet, and this is worth knowing before you rely on the app: if you delete Lexi without a device backup, what you wrote is gone. Export is the feature most likely to arrive next. If it matters to you, say so in an email and it moves up the list.
Does Lexi collect my data?
No. There are no accounts, no analytics, no crash reporting, and no ads. Full details in the Privacy Policy.
What devices does Lexi support?
iPhone running iOS 18 or later. Lexi supports Dynamic Type throughout, so it follows whatever text size you have set.
Something is behaving oddly. What do I do?
