Every Jacksonville project follows four phases: Discovery & Strategy (1 week), UI/UX Design & Prototyping, Agile Development in two-week sprints, and QA & Launch with four weeks of complimentary post-launch maintenance.
Step 01
We start by understanding your business, your users, and what success looks like. This phase produces a clear project scope, technical architecture, and timeline.
Step 02
Our designers create wireframes and high-fidelity mockups. You review and approve designs before a single line of code is written.
Step 03
We build in agile sprints, delivering working features every two weeks. You get access to staging builds so you can test progress in real time.
Step 04
Every feature goes through manual and automated testing across devices and platforms. We catch bugs before your users do.
Step 05
We handle App Store and Google Play submissions, server deployment, and launch-day monitoring. Most projects go from kickoff to launch in six to eight weeks.
Step 06
Software doesn't end at launch. We provide ongoing post-launch support, maintenance, bug fixes, and feature updates to keep your app running smoothly and your users happy.
Our service area covers Duval County, St. Johns County, and greater Northeast Florida:
Mobile app development Jacksonville pricing typically ranges from $25,000 to $250,000 depending on complexity, platform, and feature scope.

Most of our mobile app development projects launch in six to eight weeks from kickoff.
