Reporting a bug takes longer than finding it

Can't reproduce it It happened once, and the path is gone.

Questions

How do I write a good bug report for an iOS app?

A good report has the steps, the expected result, the actual result, the video and the logs. LastBug puts them together from your recording.

How do I reproduce a bug I saw once?

Record while you test, so the path to the bug is saved. With Pro, your taps can be replayed.

Can I record the iOS Simulator screen for a bug report?

Yes. LastBug records the Simulator screen and your voice while you test, and saves the video with the bug.

Do I need to change my app to use LastBug?

No. Use the Debug build you already run.

Which AI tools does it work with?

AI tools that support MCP. LastBug has no AI of its own: you bring your AI coding tool, or use none.

Is my data sent anywhere?

No. Recordings stay on your Mac. A task leaves LastBug only when your own AI tool takes it.

How do I check that a bug is really fixed?

Pro replays your taps on the fixed build so you can check the fix. You decide when the bug is done.

What does the Free plan include?

One project, up to 10 recordings, 10 tasks a month for your AI tool and 3 check results per recording. At a limit your recordings stay.

What do I need to run LastBug?

A Mac with Apple silicon, macOS 14 or later, Xcode 16 or later with an iOS 16 or later Simulator, and a Debug build of your app.
