Exactly this! There needs to be some sort of reward for the user to keep up with checking in. I imagine something like tamagotchi where you have to feed a pet like creature that also checks in with you/ asks your mood or smth
Love the Tamagotchi idea! I want to keep it low-pressure, but subtle rewards like streaks or small milestones could help people stick. Would a playful element actually make you log more, or feel gimmicky?
