There is no doubt that modern society relies heavily on mobile apps, with the global app market generating $462bn in revenue worldwide in 2019. However, not everyone has the necessary expertise or resources to develop a mobile app in-house, creating an opportunity for outsourcing app development. Outsourcing can take various forms, including offshore software development, freelancers, and software agencies and firms. While outsourcing offers several benefits, such as saving money, focusing on different aspects, reducing risk, hiring specialist talent, and rush-to-market capabilities, it also has its drawbacks, including compromising the SDLC, communication challenges, continuous support issues, security risks, unexpected issues, and potential loss of control over the development process. On the other hand, in-house app development offers advantages such as easy coordination, conveying company ethos, resource management, ensuring a quality product, investing in the future, but also has its own set of challenges, including hiring the right expertise, time constraints, and high costs. Ultimately, the choice between outsourcing and in-house app development depends on various factors, including budget, resources, expertise, and priorities.
