we've been using this extensively in our app and it has been helpful in finding hidden latencies, errors within our systems and overall app's foundational layers.

trace spans can provide in depth analysis of each step of execution for apps, think distributed system tracing but for different architectural layers of mobile app. additionally if backend is instrumented by otel compliant client, a single trace can travel from app to backend

the library provides batteries included implementation of instrumentations around startup, http latencies, frame drops, sessions along with pre built metadata such as screen names, model, network providers which helps in debugging issues

We use Cloudflare which does something similar with its edge servers.

Nice, will check out TCP window. Most of our problems are at DNS, IPV6 routing, VPN. Some solved, some on the way!
