This document provides a mobile app pre-launch checklist to ensure an app is perfect for launch day. It recommends checking for bugs, establishing good user interface and user experience, perfecting design efforts, ensuring backend services are optimized, and that the end user license agreement and terms of service are clearly defined. The checklist includes specific items under each category to validate, such as checking for bugs like screen freezing, proper handling of network issues, and that closing and reopening the app runs smoothly.
