- The English 'app' is narrower, almost exclusively for software.
Common Mistakes
- Using it as a countable noun without an article where needed (e.g., 'I need app for maps' vs. 'I need an app for maps').
- Confusing 'app' (software) with 'application' (which can also mean a formal request, e.g., job application).
