It depends on lots of different factors, from your project size to your current staff and budget. You can bulid an app in-house, you can hire a freelancer or you can partner with a mobile app development company.
If you don’t have any tech expertise in your company, you’ll need to either hire developers, or hire a development company. Hiring developers is challenging, because you’ll need to take care of everything, from HR and conducting interviews (how will you interview a tech expert, if you have no specialist in-house to assess their skills?) to taxes, equipment and workplace.
Moreover, mobile app development companies provide you not only with developers, but also with other specialists like:
business analysts who create technical specifications for the projects
quality assurance specialists who test your app on each stage of development
project managers who make sure your app is delivered on time and budget
designers who develop UI and UX design of your app
I can hardly imagine a high-quality app made without such a team, and hiring it in-house is so time-consuming and costly, that outsourcing is really the best option for most cases.
