Translating behavioural research into tangible interface solutions is central to executing ethical product design. Building directly from the qualitative findings in COMM2442, where 100% of survey respondents reported feeling trapped by streak coercion and 80% experienced notification dread, this project presents Casual Learning Mode. Rather than overhauling the core app for users who thrive on competition, this parallel mode lives as an intentional toggle within user preferences, offering an emotionally safe, self-paced space for anxious or burnt-out language learners.
