Give three reasons why building apps might not be the sole source of income for an individual.

Correct Answer:

Building apps may not be a person's only source of income for several reasons. First, the app market is very competitive, so many apps do not earn enough money consistently. Second, income from apps can be unpredictable because sales, downloads, and advertising revenue may rise and fall. Third, many app developers work on short-term contracts or freelance projects, so they often need another job or additional clients to maintain steady income.
