Comprehensive iOS crash reports
Faster debugging with in-depth reports, right out of the box
Swift stack trace
Upload dSYMs
See a full, desymbolicated stacktrace in every crash report. Debug knowing the exact method name and line number that crashed.
Automatically collect debug info
All the details you need to reproduce and fix a bug are automatically collected in a detailed report including device model, OS version, battery state, thread state for all threads, and more.
Automatic breadcrumbs
Common events leading up to a crash are automatically captured, so you can reproduce crashes with certainty and prove you've fixed a bug. Auto-capture not enough? Go further and customize breadcrumbs using the NSNotification pipeline.
Full control over your crash reports
All information in your crash report is customizable. You can modify crash reports before they're sent with additional diagnostic data if what we're capturing isn't quite enough.

Intelligent crash grouping
Prioritize the most harmful bugs first, with tools that help you cut through the noise and discover critical bugs
Reliable, best in class error grouping
Identifying which errors happen most and hurt the most users is powered by Bugsnag's intelligent error grouping. Aggregating errors by root cause decreases noise in your notifications and helps you assess impact.
Filter iOS crashes
Powerful filtering and sorting
Find specific errors that need investigating, like those affecting a certain version of your app, or a user reported bug. Filtering updates user and event counts so you can assess impact from a zoomed in view of your data.
Know when problems spike
If a backend or API change causes a spike in errors, Bugsnag alerts you immediately. The error spiking algorithm uses an exponential moving average to identify anomalies in your error rate.

Get started in minutes or dig deeper
You'll see value in minutes with Bugsnag's quick installation, but if you need to dig deeper, you can customize at the nuts and bolts level to meet your requirements.
Async safe
Bugsnag's Cocoa library is async safe so you can be sure crash handling is graceful when your app is in a delicate state. After a crash, Bugsnag writes the report to disk and sends it along in the next launch.
Detect NSError instances
Capture NSError instances, too, so you can debug network connectivity issues or database failures, even if your app didn't completely crash. Learn more about our product.
