I've created and packaged an app using the App Designer, and I want to share it.
However, I only want others to use my app and not have access to the app code.
Is it possible to package an app without making the code inaccessible?
Is the code inaccessible when using app packing function in the MATLAB?

Thanks a lot. I have packeged with application complier, then,
I was just wondering if the code is automatically encrypted when using the application compiler.

Yes, Application Compiler encrypts m-files automatically. Note that the compilation uses AES (Advanced Encryption Standard), which is different from p-code. P-codes obfuscate codes.
Information on encryption is not fully documented, but you can find hints in the doc below.

Perhaps the most straightforward way is to convert your m-code to pcode (doc pcode for more details). Compiling is another option, but it may be more involved (need compiler).

Ah, I agree. p-code can be a convenient way to go. For OP's information, one can export apps into "m" file.
This can be obscured with pcode.
