Case Study: The Bible App

Remember & Share (Hooked — by Nir Eyal)

• The Bible App was far less engaging as a desktop website; the mobile interface increased accessibility and usage by providing frequent triggers.
• The Bible App increases users’ ability to take action by front-loading interesting content and providing alternative audio version.
• By separating the versus into small chunks, users find the Bible easier to read on a daily basis; no knowing what the next verse will be adds a variable reward.
• Every annotation, bookmark, and highlight stores data (and value) in the app, further committing users.
