Top 5 Mobile App Design Agencies in the USA

Design Studio, Goji Labs, Blue Fountain Media, Digital Silk, and Appinventiv — these are some of the most highly rated app design agencies in the USA. In this article, we’ll profile these leading agencies in detail and explain why so many mobile app companies team up with them.

Running a mobile app involves continually overcoming extremely complex challenges. Firstly, the odds are stacked against you. 99.5% of consumer apps are not able to achieve their goals. Following installation, an average app loses 77% of its Daily Active Users within the first 72 hours. Within a month, the percentage of lost Daily Active Users goes up to over 90%.

This is not all. Your app faces competition from over 1.6 million apps on the Google Play Store and 1.9+ million on the Apple App Store.

If you are running a mobile app in the USA, the list of challenges is even longer. Navigating regulations related to data privacy and app store guidelines in the US is very taxing. User acquisition with a limited budget is very difficult. Moreover, startups considering mobile app creation face a lot of challenges while attracting investors as investors are now hesitant to fund new, unproven projects. Thankfully, there is an easy way to avert these challenges –working with a top, US-based app design agency.

Why Work with Mobile App Design Agencies in the US?

US-based app design agencies know all the challenges local app makers face and have appropriate solutions. These agencies employ best design practices to create apps that are marketable to both users and investors. They conduct market research to ensure their apps are pre-optimized to meet user expectations and for rapid adoption. They also ensure that app designs comply with relevant regulations.

5 Leading Mobile App Design Agencies in the USA

Here are the 5-leading mobile app design agencies in the US helping local app makers beat the odds and succeed in 2025.

1. Design Studio UI UX

New York City is home to many highly-rated mobile app design agencies. But, out of all these agencies Design Studio stands head and shoulders above.

In the past 10 years, the firm’s human-centered app design practices have helped numerous brands establish strong online presence. By prioritizing user needs through extensive research and persona development, the team ensures that each mobile app created is primed for adoption.
