@Pritivi7 We don't have any dedicated features to measure mobile app load time, but we do have a Timed Events feature in our mobile SDKs, which enables you to generate timing metrics for defined events. Please see here for documentation:
https://docs.tealium.com/platforms/getting-started/timed-events/. Does this help for your use case?
