Mobile apps have become an essential part of our daily lives, with millions of people using them for various tasks such as communication, shopping, entertainment, and more. As a result, it's critical that mobile apps are reliable and perform as expected. Here are a few reasons why mobile apps need coverage:

1. User Experience: A well-covered mobile app provides a seamless user experience, ensuring that the app functions smoothly and without any interruptions. Poorly tested apps can result in crashes, slow performance, and other frustrating user experiences that drive people away from the app.
2. Security: With the increasing use of mobile apps for sensitive tasks such as banking and online shopping, it's crucial that the app is secure. Thorough coverage helps identify security vulnerabilities and ensures that the app is protected from potential attacks.
3. Cost-effective: Finding and fixing bugs early in the development process is much cheaper than fixing them after the app has been released. Regular testing and coverage help identify issues early, reducing the cost of fixing them and minimizing the impact on the user experience.
4. Compliance: Mobile apps must comply with various regulations and standards, such as privacy and data protection laws. Testing and coverage help ensure that the app meets these requirements and protects user data.

In conclusion, comprehensive coverage is essential for ensuring that mobile apps are reliable, secure, cost-effective, and compliant. It plays a critical role in providing a positive user experience and ensuring that the app is successful in the market.

Not having adequate coverage can lead to more significant costs and headaches for developers in the future. When bugs and issues are not caught early in the development process, they can accumulate and become much more difficult and expensive to fix later on. For example, fixing a small bug in the early stages of development may take only a few minutes, but the same bug can take hours or even days to fix if it's not discovered until later. Additionally, if the app is not thoroughly tested, it can result in significant user complaints, leading to negative reviews, low ratings, and decreased app usage. This, in turn, can harm the app's reputation, reduce its visibility in app stores, and reduce its potential to generate revenue. In the worst-case scenario, the app may need to be taken down, which can result in significant costs and a loss of credibility for the founder. Therefore, investing in comprehensive coverage is a wise decision that can save developers time, money, and headaches in the long run.
