# Card mastery levels in Keeplet

Applies to: website and Android and iPhone app · Last updated: 2026-10-29

In Keeplet, a card's mastery tells you how well you know it. In the statistics of the website and of the Android and iPhone app, cards are split into three groups: **new** (never reviewed), **learning** (you are still fixing them) and **learned** (they only come back now and then). A card becomes "learned" when you have remembered it more than 10 times in a row and its ease factor is at least 2.5.

## The three groups in the statistics

On the **Statistics** tab of the app and on the Statistics page of the website, under "Where you stand with your N cards", you will find:

| Group | Label | Description in the interface | When a card falls into it |
|---|---|---|---|
| New | "N new" | never reviewed | The successful-reviews counter is at zero: a card never reviewed, or one whose last rating was **Not at all** |
| Learning | "N learning" | you are still fixing them | At least one successful review in a row, but not yet learned |
| Learned | "N learned" | they only come back now and then | More than 10 successful reviews in a row and an ease factor of at least 2.5 |

Below that you will also find the "By notebook" list, showing how many cards in each notebook are learned and how many are due today.

## When a card becomes "learned"

Two conditions are needed together:

1. **More than 10 successful reviews in a row**, that is, from the eleventh on. The counter counts the ratings other than **Not at all** since the last time you got it wrong.
2. **An ease factor of at least 2.5**, the starting value of every card.

The second condition matters more than it seems. With **Great** (website) or **Perfectly** (app) the factor rises by 0.10 at every review; with **Somewhat** (website) or **Fairly well** (app) it drops by 0.14, with **A little** by 0.32. A card you always rate **Somewhat** / **Fairly well** never reaches the learned group, because its factor falls below 2.5 at the very first rating. To get there you mostly need **Great** / **Perfectly**. The calculations are in [The SM-2 algorithm in Keeplet](/en/help/concepts/sm2-algorithm-in-keeplet).

If a learned card receives **Not at all**, the counter goes back to zero and in the app the card returns to "new", because the group looks at the successful-reviews counter. Then it climbs again: "learning" from the first successful review, "learned" again after more than 10.

## What the interface says

The note under the website chart says: "Learned: more than 10 successful reviews in a row and ease of at least 2.5." This is the same rule described above, applied by the server. The statistics screen of the app shows the same sentence.

## Differences between the website and the app

- **Thresholds.** The thresholds for the "learned" group are the same in the app and on the website: in the app the phone calculates them, on the website the server does.
- **New and learning.** The app counts a card as "learning" right after the first review. On the website a card's status updates one review late, because the server calculates it on the number of reviews before the one just done: a card reviewed only once may still show among the new ones until the second review.
- **Numbers.** For these two reasons, website and app counts can differ slightly when cards have been reviewed only recently.

## The five levels described on the website

The public "Spaced repetition" page of the Keeplet website and the Info panel describe a five-level scale, based on the accuracy of your answers (the share of successful reviews out of the total):

| Level | Condition described |
|---|---|
| New | Not yet reviewed |
| Learning | You have started reviewing it but accuracy is still low |
| Intermediate | Accuracy between 70% and 90% with at least 3 reviews |
| Advanced | Accuracy of at least 90% with at least 5 reviews |
| Mastered | "Mastered" status assigned by the calculation (the same conditions as learned cards) |

These five labels do not appear on individual cards or in the website or app statistics: there you only see the three groups from the previous section. The app does not use the five levels.

## How to use these numbers

There is no target to hit: the "learned" group tells you which cards you have consolidated, the "learning" group which ones still need close-together reviews. If many cards stay in "learning" or fall back to "new", try writing shorter cards and rating more honestly, as explained in [How to rate a card](/en/help/app/rate-a-card).

## Frequently asked questions

### Why doesn't my card become "learned" even though I always remember it?

Almost always because of the ease factor: if you rate it **Somewhat** / **Fairly well**, the factor drops and stays below 2.5. With **Great** / **Perfectly** it rises. You also need more than 10 successful reviews in a row.

### What happens to a learned card if I get it wrong?

With **Not at all** the successful-reviews counter goes back to zero and the ease factor drops by 0.80. In the app the card returns to "new" and rebuilds its path from the start.

### Are learned cards no longer reviewed?

They keep coming back, but at very long intervals. The "learned" group carries the hint "they only come back now and then".

### Where do I see mastery in the app?

On the **Statistics** tab, in the "Where you stand with your N cards" section, and in the "By notebook" list. It also works without an account.
