# In-App Frames | Sentry for watchOS

The main executable and frameworks inside the application bundle will be marked as `inApp`, while well known and public frameworks such as UIKitCore, CoreFoundation, GraphicsServices, and so forth will be marked as `not inApp`.

To fine-tune this behaviour, define [Stack Trace Rules](https://docs.sentry.io/concepts/data-management/event-grouping/stack-trace-rules.md#stack-trace-rules) for your project. This will allow you to mark specific frameworks as `inApp` or `not inApp`, depending on whether you consider them part of your business logic, or third party dependencies. For reference, you can read up on the [default stack trace rules](https://github.com/getsentry/sentry/blob/20b05fc91a4ad6783bff1875327f4570bcfb5d00/src/sentry/grouping/enhancer/enhancement-configs/newstyle%402023-01-11.txt#L4).
