Your app launch represents a critical moment for users, as it's their first interaction with your app. Slow launches impact user device memory and battery life, perception of your app and brand, and business metrics. Optimizing app launch times is crucial to achieve a short gap between launch and interactivity, which is now more important than ever before. The goal is to reduce launch times while also ensuring the quality of your app. To achieve this, you need to identify and address various components that impact startup times, such as unused assets, expensive work, placeholder content, prioritization of work, slow startup stages, memory usage, dependencies on external frameworks, optimization of first screens, splash screens, and testing obsessively. By implementing these strategies, you can set and reach performance goals, improve user experience, and ultimately increase business metrics.
