The inability to directly practice specifically to regain “hearts” (Duolingo’s term for attempts/lives) on the Duolingo platform represents a specific limitation within the app’s design. Users are unable to engage in targeted exercises solely for the purpose of replenishing lost hearts. For example, completing a lesson with no errors will earn experience points, but will not restore a heart lost in a prior lesson.
This restriction is integral to Duolingo’s gamified learning structure. It encourages users to approach lessons with increased caution and focus to avoid errors that lead to heart depletion. Historically, this system was implemented to motivate consistent, careful engagement with the learning material, discouraging rushed or careless attempts. The scarcity of hearts encourages users to consider Duolingo Plus, the paid subscription service, for unlimited attempts.
