💡use 'onto' or 'to' for adding software to a device, not 'in'.
❌Please open app and check.

Outside of a phone or tablet context, 'app' often appears next to a clue word that names the task (drawing, email, writing) so listeners know what software is meant.

常見錯誤

❌For starter, I will have an app.
✅For a starter, I will have an app.
💡'starter' is a countable noun and needs an article.
❌I ate an app as my main dish.
✅I ate an app before my main dish.
💡apps come before the main course, not in place of it.
