The mobile clients (both AnkiMobile and AnkiDroid) use the word “Reset” while the Desktop client uses the word “Forget”. I feel that the terms should be unified across platforms to decrease confusion.
From AnkiMobile Docs:
Reset Card
Turn the current card back into a new card.
From AnkiDroid docs:
Reset progress
Move the card to the end of the new card queue. The current state of the card is cleared, but not its revision history.
From Anki docs:
Forget
Move currently selected cards to the end of the new queue. The existing review history is preserved. In 2.1.50+, there are options to restore the original card position, and to reset the card’s lapse and repetition counters.
If you ask me, I think that the word “Reset” conveys the function of the option better.
The functionality is inconsistent too, i.e., the mobile clients don’t restore the original card position, or reset the card’s lapse and repetition counters. But that’s a different issue.
