Top Mobile App Development Companies in the USA

1,308 IT service providers ranked by rating, review volume and listing quality.

Mobile app development covers applications built for phones and tablets, whether native to one platform, cross-platform from a shared codebase, or a web application wrapped for the stores. All three are sold under this heading and they have materially different costs, both to build and to keep running.

The recurring surprise for buyers is that shipping is not the end of the spend. Both stores change their requirements on their own schedule, and an app that is not updated will eventually stop being accepted or stop working. Ask what the maintenance arrangement is before comparing build quotes, because a lower build price with no maintenance path is not the cheaper option.

Between them, the 600 best-ranked of these 1,308 IT service providers cover web development (563), android (424), web design (357) and iOS app (334). They also list work in California, New York, Oregon and Texas. 593 of them have written a profile you can read before you get in touch.

How many mobile app development companies are there in the USA?

1,308 companies on TrustList offer mobile app development and are based in the USA. That makes the USA the largest mobile app development market we rank.

How is this ranking worked out?

Each firm's position comes from its client reviews and its profile, blended into one score:

Rating, smoothed so a single five-star review cannot outrank a firm with hundreds of good ones
Review volume, with diminishing returns
Profile completeness: the details a buyer needs to judge the firm
Earned trust: verification and awards, as a small lift

No firm can pay for a position. Sponsored listings are labelled and shown apart from this list. How rankings work

What else do firms in the USA offer?

We also rank web development (2,396), web design (1,857) and e-commerce development (1,095) in the USA.
