Gamification tactics
Streaks, points, levels and other game mechanics apps used to lift engagement and retention. 29 tactics from 27 founder interviews.
Most founders added streaks, points, ranks or celebration moments to the daily action their app was built around, and the reported effect was mainly on retention and engagement. A few measured it, with gains from 17% to roughly double; most described the lift without numbers. Others built the whole product as a game, turning to-do lists, focus timers and workout logs into XP, collectibles and ranks.
- Tiimo said a more celebratory animation when a task is marked done brought 17% more completed tasks, and Jungle said a tree growing as students answer questions raised questions answered by about 70%.TiimoJungle
