The document discusses optimizing the first-time user experience in mobile apps. It notes that 25% of users will only open an app once and most will only open it a few times. A case study of a fashion app found that only 14% of new users created profiles after mandatory registration. A/B testing alternative first-time experiences found that removing registration and providing in-app tips increased profile creation to 26%, while removing registration and offering incentives increased it to 44%. The key lesson is that first-time experiences are critical to an app's long-term success even though they may only last a minute.
