Session Timeline

A stack trace shows the line. The session shows why it broke.

Every crash comes with the whole session behind it: lifecycle, screens, taps, events, logs and network calls, in the order they happened. Read it top to bottom and the cause is right there, no reproduction needed. See it in your dashboard, or ask your AI Agent to read it over MCP.

Built from your breadcrumbs, next to your crash reports. Works on iOS and Android.

The whole session, in order, straight to the crash.

The problem

A stack trace is a location, not a cause.

You get a crash at 2am: a null reference on line 247. It tells you where the app died, but not how the user got there. Logs live in one tool, events in another, and the real journey is stuck in a ticket titled "app crashed pls fix." So you burn hours trying to reproduce it.

Every one of these is a question a bare stack trace cannot answer:

What screen was the user on?
What did they tap right before it?
Was there a network timeout?
What events fired in the last 30 seconds?

The session timeline answers all four before you finish reading it.

Your AI Agent, on the case

Ask why it crashed. Get the session back.

Read the timeline yourself in your AppAmbit dashboard, or point your AI Agent at it over MCP. It walks the same record and answers in plain language, with the steps that led to the crash.

Found the cause? Flip a flag from the same dashboard with remote config.

One record, every signal

Everything the app did, in one place.

Your breadcrumbs are the automatic markers. The session timeline is where they line up next to your events, logs, network calls and the crash itself, in one chronological record.

Lifecycle

App start, resume, pause and background, captured automatically.

Screens

Every screen and page view, in the order the user opened them.

User actions

Taps, form submits and the navigation they set off.

Events & breadcrumbs

Your tracked events and the automatic breadcrumb markers, inline.

Logs

Diagnostics your app prints, sitting in place in the record.

Logs & crashes →

Network

Requests, timeouts and failures, with the timing around them.

Root cause: null response on retry, line 247.
A real debug

Read the session, find the fix.

The app crashes after a tap on "Save." You do not reproduce anything. You read the record: the user opened Profile Edit, tapped Save, the POST timed out twice, the retry got a null response, and the next line is the crash. The cause is in the steps.

No repro. No steps pulled from a support ticket. The story is already recorded.

Hours to minutes

Reproduction and log-diving collapse into one read.

Fix, not guess

You patch the real cause, so it does not come back.

Side by side

Timeline vs traditional crash reports.

The old way

Just a stack trace
Invisible before the crash
You reproduce it by hand

Why it matters

Fast releases need fast debugging.

You ship weekly, sometimes daily. Flags flip, pipelines run on their own. When debugging is the slow part, everything backs up behind it. Reading a session instead of reproducing one keeps you moving.

Ship faster hotfixes

Find and fix a crash in minutes, then get the patch out before users churn.

Fewer rollbacks

See exactly what broke and fix it surgically, instead of rolling back a whole release.

Ship with confidence

When any crash is one session read away from a fix, you ship without holding your breath.

How AppAmbit does it

Nothing to wire up for the basics.

Start the SDK once and lifecycle, screens and sessions are recorded for you. Add your own events and breadcrumbs to make the record richer. Every crash arrives already linked to the session behind it.

Auto-linked to crashes

Every crash opens with its own session already attached. No searching, no correlation by hand.

Crash monitoring →

One chronological view

Lifecycle, screens, actions, events, logs and network all fall into a single ordered record.

Build and device context

Version, build number, OS and device ride along, so you know exactly what you are debugging.

Audience →

Works everywhere

The timeline is there even for builds you did not distribute through AppAmbit.

Questions

Session timelines, answered.

Do I have to instrument anything?
No. Start the SDK once and lifecycle, screens and sessions are recorded for you. Add your own events and breadcrumbs when you want the record to be richer.
How is this different from breadcrumbs?
Breadcrumbs are the automatic markers. The session timeline is where those markers line up with your logs, network calls and the crash, so you can read a whole session to its root cause.
Do I need to reproduce the crash?
No. The session behind it is already recorded, so you read what happened instead of trying to make it happen again.
Does it work on builds I did not ship through AppAmbit?
Yes. The timeline is captured by the SDK, so it is there for any build running it, however it was distributed.
Can my AI Agent read the timeline?
Yes. Read it yourself in your AppAmbit dashboard, or point your AI Agent at it over MCP and ask why a crash happened.
