Advantages:

• considered a requirement, by some, for maintaining a proprietary commercial advantage (this may not apply to public health Apps).
• sloppy work (including potential security issues) can be more easily hidden from the public.

Disadvantages:

• no independent verification of claims by App Creators can be performed;
• potential App Users may not trust the App.
