Flashcards & Spaced Repetition

Flashcards are one of the best ways to remember things for the long term. Aletheia's flashcard system uses spaced repetition — a proven method that shows you cards at just the right time so you don't forget.

What Is Spaced Repetition?

When you first learn something, you need to review it soon to remember it. But once you know it well, you don't need to review it as often. Spaced repetition tracks this automatically:

Cards you struggle with → shown more often
Cards you know well → shown less often (but not forgotten!)

Over time, you'll remember more with less study time. 🧠

Where Do Flashcards Come From?

You don't have to make them yourself. Aletheia makes flashcards for you after you learn:

After a tutoring session ends — cards about things you found tricky, or key ideas from the lesson. Very short sessions don't make cards.
After a quiz — cards for the questions you missed. A perfect score doesn't make any cards.

New cards can take a minute or two to show up after a session or quiz.

You can also make cards yourself. See Making New Cards below.

How to Review Flashcards

Tap the Flashcards tile on Home. When cards are due, it has a "due" badge.
Tap Review Due Cards (Start Reviewing! for younger kids).
Read the question and try to remember the answer.
Tap the card to flip it.
Rate how well you remembered:
- Wrong — I didn't know this (younger kids see Didn't Know)
- Hard — I got it, but it was difficult (younger kids see Tricky)
- Correct — I knew it right away (younger kids see Got It!)

Your rating tells Aletheia when to show you that card again.

Note: The Flashcards tile is always on Home. If it says No cards due, you're all caught up. You can still open it to practice, browse, or make new cards.

Browsing Your Cards

Under Browse by Subject (My Subjects for younger kids), your cards are grouped by subject and topic. Tap a subject or topic to open it, review just those cards, or practice them all.

Understanding Your Progress

Your cards are sorted into three groups:

New — cards you haven't reviewed yet
Learning — cards you're still working on
Mastered — cards you've remembered over a long stretch (they now come back only every 21+ days)

Practice Mode

When nothing is due, you can still tap Practice Mode (Practice Again! for younger kids). Practice is just for fun. It doesn't change when your cards come back.

Making New Cards

At the bottom of the Flashcards page is Generate New Cards (Make New Cards for younger kids).

Pick one of your subjects.
If you like, pick a topic. Or leave it on Whole subject (A bit of everything for younger kids).
Tap Generate New Cards. Aletheia makes a set of new cards for you.

You can make new cards a few times a day. If you've hit the limit, try again tomorrow.

Something Wrong With a Card?

If a card looks wrong or confusing, tap Report issue (Something wrong? for younger kids) and pick what's wrong. Your parent will be told, and they can fix or remove the card.

Tips for Better Flashcard Sessions

Review daily — even a few minutes keeps your memory fresh
Be honest — marking "Correct" when you guessed won't help you learn
Don't rush — take a moment to really think before flipping the card
