App Partner is a Brooklyn-based mobile app developer specializing in the design, development and deployment of apps for iOS and Android.

We offer end-to-end mobile services from branding and strategy through coding, testing and post-launch optimization and consulting. But, true to our name, it’s our mission in every engagement to also deliver…

Solutions-Based Technology

Our team tackles traditional problems with not-so-traditional solutions. We’re always open to exploring new technologies, so whether you’re looking to innovate or simply excel, we bring the latest mobile intelligence to the table.

Close Collaboration

Be as involved as you want to be. Work out of our office for a day, do a screen share session with our designers, or simply check in during the weekly conference call. Our team is your team.


Beyond developing apps, we’ve provided on-site support during critical demos, helped startups hire their first employees and delivered mobile business insight to corporate marketing teams. Whatever your needs, we’ll do what we can to help.

A Long-Term Vision

The work of building a successful mobile app doesn’t end at launch. Strategic improvements include optimizing performance, capturing new opportunities and more. That’s just the type of long-term relationship we excel at.

Made in Brooklyn

Our location gives us access to the best strategists, developers, designers and account managers in the world, not to mention real strategic benefits. We believe in the doing the job right—and that means doing the job in Brooklyn.
