Top 10 Mobile App Development Firms

Last updated Jul 23, 2019

When it comes down to choosing the right app agency to turn to, we know what we're talking about. Savvy Apps has been in the industry since 2009, just around when apps could start being built. During that time we've had the privilege of watching other app agencies grow into their own along with us.

There are a number of companies that we respect as peers. For some of them, we have even chatted with their founders, sharing ideas and industry experiences. Like us, many of these companies started creating apps back in the beginning of the app stores. Not everyone will end up working with Savvy Apps, whether it's due to timing, our capacity, or there not being a mutual good fit. Since we're often asked for referrals, here, in no particular order, are our picks for the top 10 app design and development companies to consider when starting your own app.
