Initial tracking
Events are implemented
and firing.
Trust your analytics. Release after release.
App updates can quietly break the tracking behind your reports. Echo helps your team catch the gaps and verify what changed.
You test your app with every update.
But tracking can still break unnoticed.
A checkout completes. A customer registers. A subscription starts.
The events describing those actions may be missing, incomplete, or incorrect.
App update
The app changes,
like a new checkout flow.
Purchases drop?
The report shows fewer
purchases after the release.
Reporting question
Was it a real drop
or a tracking issue?
