I spent six years thinking I was bad at mobile observability. I wasn’t.

When people say mobile observability is hard, they usually mean complicated. I mean something more specific: mobile breaks the foundational assumptions backend observability tools were built on. Not harder — structurally different.

Three things in particular.

Network reliability. Backend systems assume a stable connection to ship telemetry. Mobile doesn’t have that. Devices lose connectivity, switch networks, go into airplane mode mid-session. Data queues for hours before it transmits — or gets dropped when the OS cleans up background processes. Default OTel exporters assume the batch span processor can flush on a timer to a reachable collector. On mobile, neither the timer nor the collector is reliably there.

Device fragmentation. “P50 latency is 200 milliseconds” sounds useful until you ask: for which devices? What’s fast on a flagship is slow on a three-year-old budget Android — and a real portion of your users are on those devices. Aggregated metrics flatten all of that into something that doesn’t represent the users actually struggling.

Resource constraints. Mobile operating systems kill background processes in ways backend infrastructure doesn’t. When that happens, you lose whatever telemetry hadn’t shipped yet. Instrument too aggressively and you hurt performance on the exact devices where you most need visibility.

None of this is an edge case. It’s the default environment for a significant portion of your users. And most of the tools engineers reach for were designed for environments where none of these constraints exist.

The vanity metric trap

Most mobile teams track the same things: crash rate, P50 launch time, network latency percentiles. Real numbers. They just don’t answer the question that actually matters — how did this technical change affect real users?

Your app startup improved from 3.2 seconds to 2.9 seconds. Sounds good. What was the user impact? Without user-level context, you’re optimizing a metric that may not move any business needle.

The version of this I lived through most often: a backend dashboard showing all green, support tickets climbing, and no clear link between the two. No crash. No error log. Users hitting something broken, giving up, not coming back. That’s not a rare failure mode. That’s what sampled, backend-first observability looks like from the user’s side.

What changes when you can see the full session

The difference hit me the first time I pulled up a session timeline for a user whose app had hit cascading API errors from a cold start.

Every network call was there in sequence, color-coded by what happened. You could see where the retry logic started stacking up. You could see the exact moment the app got overwhelmed and crashed — and because dSYM uploads are automated, you could jump straight to the line of code responsible. Everything that led up to it, in order, in the context of what that user was actually trying to do.

That’s not a crash report. It’s a full reconstruction. A crash report tells you something broke. A session timeline tells you why, for whom, and under what conditions. If you want to see this kind of end-to-end visibility in practice, we walked through it in depth in our recent OpenTelemetry session.

The other thing that changes: where the data lives. Because Embrace is built on OpenTelemetry, mobile telemetry forwards into whatever backend your team already uses — Grafana, Chronosphere, Honeycomb. Mobile engineers and backend SREs end up looking at the same dashboards. A crash that’s actually rooted in a backend latency issue becomes visible to both teams at once, instead of after a multi-day investigation where everyone’s working from different data.

Why this took so long

Mobile has been the blind spot in observability for a long time. Not because the engineers working on it weren’t good. Because the ecosystem treated mobile as a subset of backend monitoring, when it’s actually a different problem.

The release cycle made it worse. Backend: deploy, get feedback. Mobile: build, test, app store review, gradual rollout, then finally start collecting meaningful data. Four-to-six week feedback loop. By the time you have answers about a performance change, you’ve already shipped three more.

A lot of senior mobile engineers I’ve talked to have some version of the story I had. Years of feeling like they were missing something obvious, working around tools that weren’t built for their environment, quietly absorbing blame for problems that were actually tooling problems.

That’s what’s changing. Not just better instrumentation. A different starting assumption about what mobile engineers should be able to see.

Last thing

The other shift is how you get at the data. Instead of learning a query language or clicking through filters, you can ask in plain English — “show me crashes in Illinois” — and go straight to the answer. We’ve also shipped an MCP server so you can query sessions, crashes, spans, network calls, and logs from whatever AI tool you already work in. Less time in the UI, more time fixing things.
