RB App Checker Lite helps users and developers to check code signatures and receipts for applications from any source. Did you get that application from the App Store or from an authorized developer? Easy to tell.

It will show certificates, requirements and entitlements, embedded provisioning profiles, auxiliary executables and frameworks, cross-check all this information for consistency, and check that the application's resources have not been altered after signing.

Check if your application is properly signed before submitting it to the App Store or publishing it elsewhere, or if the application you downloaded has been tampered with.

For your convenience, RB App Checker Lite also publishes a Service (right-click on any application in the Finder) and has a fast-select menu for all running applications.

RB App Checker will also work for Xcode archives, frameworks, command-line executables, and most other bundles containing executable code.
