Animations are fundamental in enhancing user experience within consumer apps, guiding users and establishing a memorable brand identity. Lottie animations emerged as a popular format, enabling the integration of complex animations efficiently. However, these animations can be large files, complicating their use in apps with multiple visuals. The introduction of the .lottie format allows for significant file size reduction, optimizing resource use while maintaining functionality. Developers can choose to bundle animations locally or load them over the network, each method presenting its own benefits and challenges.
Animations enhance user experience in consumer apps, capturing attention and creating memorable experiences with elements like splash screens and loading indicators.
Lottie animations, exported as .json files, can become excessively large, affecting app performance, especially with multiple animations for onboarding and dynamic features.
The .lottie format offers a significant advantage by reducing file size by 70-80% compared to standard JSON files, ideal for dynamic and personalized content.
Bundling animations ensures fast playback but increases app size with every addition, whereas loading from a server keeps the app lightweight at the expense of fetch times.
