Statistics and the Day Streak
The app keeps track of how things are going and shows it in two places: briefly on the main screen and in your profile, and in detail on a separate statistics screen that opens from your profile.
What you see straight away
Without opening the statistics screen, you can see:
- how many words of the daily plan are done
- how many words you know, are learning and added recently
- your streak of days with a finished session
- the progress of each word, as a percentage, on its card
Detailed statistics
The statistics screen opens from your profile and shows the picture over 7, 30 or 90 days, or all time:
- the state of your vocabulary: known, consolidating, due, new
- answer accuracy and how it has changed
- average answer time
- your hardest words, the ones you get wrong most often

From the list of hard words you can start a review that covers just those.
The day streak
The streak is how many days in a row you finished the daily session. It is counted separately for each language you learn and resets if you miss a day. To avoid missing one, turn on reminders in the training settings.
Detailed statistics are part of Pro
The state of your vocabulary, the day streak and per-word progress are visible to everyone. Accuracy, average answer time, your hardest words and activity over a period come with the Pro subscription.
