A free tool for checking your app is properly signed

RB App Checker Lite will help you get your app listed on app stores by pointing out some of the flaws in your app that the app store may notice during their automated app testing bots.

Check code signatures for free

RB App Checker Lite allows you to check receipts for apps and check code signatures from any source. Check your app’s entitlements, requirements and certificates, and crosscheck all that information to be sure it is consistent before you submit your app to an app store. App stores and virus checkers will check your app for things such as certificates.

See if an app has been tampered with

RB App Checker Lite checks things such as signatures, certificates, etc., which means non-developers may also use the app for things such as checking to see if a program has been altered or tampered with after it was downloaded. Sadly, this tool has very little developer support, which is a shame because it requires frequent patching and updating in order to keep up with modern software and technology.
