Review System

What This Solves

The trap language learners fall into most often is this: remembering something is not the same as having learned it. A word feels known the moment you finish looking it up — but will you still recognize it three days later? A week later? Usually the answer is no. Aelano’s review system uses spaced repetition to remind you to look again at the right moment — words you just learned come back more often, words you already know come back at longer intervals. In only 5-10 minutes a day, the words, phrases, and sentences you saved in My Words & Sentences move from short-term memory into long-term memory.

Situations this suits:

  • You already study content in Aelano and save words in My Words & Sentences, but find you forget them right after saving them
  • You have used Anki or Quizlet before and like the spaced repetition approach
  • You want a fixed daily study ritual — 5 minutes of review on the morning commute, for example

Where to Find Review

Open Aelano, and you can see the Review entry in the bottom navigation bar or on the home screen.

Once inside, you see today’s summary cards:

  • Due today: how many cards you should go through today
  • New today: how many new words, phrases, or sentences came in from My Words & Sentences today
  • Completed: how many cards you have gone through today
  • Streak: how many days in a row you have finished your review

The streak is a gentle reminder, not a KPI. Missing a day is fine — just come back and keep going.

What Gets Reviewed

The review system is not only about single words — the words, phrases, and sentences you saved in My Words & Sentences all enter the review pool, and each card is labeled with its type:

  • Word: a basic word, the most common type
  • Phrase: a set collocation or idiomatic expression
  • Sentence: a complete example sentence, good for memorizing whole structures

Each card also carries a small badge:

  • New: appearing for the first time, having entered the review pool today
  • Review: something you have seen before that is now due

How Reviewing a Card Works

1. Look at the front

The front usually shows the word, phrase, or sentence in its original form — your job is to recall what it means. Do not rush to flip it — giving yourself 3-5 seconds to think properly works far better than turning it over right away.

2. Flip it over for the answer

Tap the card to flip to the back, which shows the full information: definition, phonetics, source, and more.

3. Rate it on three levels

There are three buttons at the bottom:

  • Don’t know: nothing came to mind at all
  • Unsure: vaguely familiar but not certain
  • Know it: you clearly remember the meaning

Once you rate it, the system uses your choice to decide when to show you that card again:

  • Rate it Don’t know → the shortest interval; it comes back almost in the next round
  • Rate it Unsure → a medium interval; you see it again after a while
  • Rate it Know it → a longer interval; it may not come back for several days

That is the core of spaced repetition — the less familiar a word is, the more often it appears; the more familiar it is, the longer the gap. The whole process is automatic; you never have to schedule anything by hand.

4. Progress bar

The top shows current / total, so you know how much is left today.

Bonus: Practice Test Mode

The review system has an advanced mode you can turn on: Practice Test.

Once it is on:

  • Cards you rated Unsure or Don’t know get an extra practice question
  • There are three question types:
    • Fill in the blank: the word is cut out of its original sentence and you fill it back in
    • Match the definition: you are given a set of definitions and a set of words and pair them up
    • Pick the sentence: you are given several sentences and choose the one that contains the word

Get it right → you see a correct-answer message and move on to the next card Get it wrong → you are asked to think again and get another try

Practice test mode suits people who want to genuinely remember rather than just recognize. The cost is another 10-30 seconds per card. You can toggle it in the review settings.

After You Finish a Round

Once you have gone through today’s cards, you see a Review complete for today summary page:

  • How many you completed
  • How many you rated Don’t know / Unsure / Know it
  • Continue studying — go back to new content
  • Back to home — end this review session

There is also a small weekly summary showing how many you completed this week, so you can see the running total.

A Few Practical Tips

  • Review at a fixed time each day: the morning commute, 5 minutes after lunch, before bed — pick the moment you are most likely to stick with. What matters is frequency, not how long a single session lasts.
  • Rate honestly: many people rate a shaky card as Know it just to get through, then forget it two days later. The system can only help you if your ratings are honest.
  • Do not add too many new words: if you add 20 new words a day, the review pool explodes and you give up after a few days of it. 5-10 new words a day is more sustainable.
  • Turn on practice test mode: knowing a card when you flip it passively and actually being able to use it are two different things. Another 10 seconds on a question makes it stick much better.
  • Do not try to catch up after a break: if a 30-day streak ends on day 31, do not try to clear the whole backlog at once — just do today’s normal due amount and let the rhythm come back on its own.

Common Questions

Where do the review cards come from?

Only from My Words & Sentences. Words you never saved there do not enter review.

Why do some words show up so often?

Words you rated Don’t know or Unsure get scheduled first — until you can rate them Know it consistently. That is by design in spaced repetition: your effort goes to the content you genuinely have not retained.

Does a word stop appearing once I rate it Know it?

It does not disappear; the interval just gets longer. It may come back days, weeks, or months later to confirm you still remember. That is why spaced repetition builds long-term memory.

Do mastered words still appear in review?

No. Once you mark a word as Mastered in My Words & Sentences, it is removed from the review pool. If one day you find you have forgotten it, mark it back to Not Mastered and it returns to the pool.

How is today’s due count calculated?

The spaced repetition algorithm decides it, combining due dates and how many new words there are. The amount fluctuates day to day — if you added a lot of new words yesterday, today’s count is higher.

What if I do not have time to finish in one sitting?

You can quit at any time and continue when you come back. Whatever you did not finish stays in today’s due list; if the day rolls over, it is merged into the next day.

Does it sync across devices?

Yes. Review progress, intervals, and rating history all sync with your account. A card you went through on your phone will not appear again on your computer.

Does review require a membership?

Basic review is available to all users.
