USING DAILY QUESTS WITHIN YOUR PRODUCT DESIGN TO BOOST RETENTION

Summary from the TLDR Design newsletter

The Zeigarnik effect, where people remember unfinished tasks better than completed ones, creates mental tension that drives users to seek closure and return to incomplete activities. Companies like Apple Watch, Duolingo, TikTok, and meditation apps successfully leverage this through features like fitness rings, daily streaks, social notifications, and progress trackers that maintain a sense of incompleteness.
