Top 8 Mobile App Development Companies & Agencies in the USA

An excellent idea is not enough for a user-friendly mobile app. You need to work with a talented mobile app development company or agency to differentiate yourself from the crowd.

In today’s world, we’re addicted to our mobile phones and hundreds of mobile apps popping up in front of us every day. Maybe you’re struggling to decide about outsourcing the development stage or making it in-house. Before presenting the best mobile development companies let’s compare these two solutions.

Mobile App Development Companies or In-House Development

Mobile app development is a fatiguing process. There are two dominating operating systems, as you know, Android and iOS. So only one app solution will not be enough for you.

Some companies follow different strategies there like focusing the one operating system first according to their customer base and then working on the other one. Whatever is your solution will be, it will take a lot of time from scratch. You can also get help from mobile app development software to build your app.


In-house mobile app development has some disadvantages if you don’t have someone who has already made mobile applications in your team. You need to hire someone to focus on it. There is nobody who fully understands what your new colleague doing is. Therefore, there is a massive interest in mobile app development companies and agencies, especially in the USA. They will start to build your app from the concept stage. After the launch, they will be working on annoying bugs.

According to your needs, your mobile app development agency will continue to work for you, but you can arrange their working hours, which is tough for a full-time in-house developer.
