App Development Services
We build apps people actually use, and keep using. From first prototype to millions of downloads, DownSouth ships mobile products that hold up in the real world.
Our app practice brings a decade of leading mobile engineering, most recently directing teams at one of the world’s largest agencies for Fortune 500 telecom, retail, and industrial brands.
Apps and platforms our
team has shipped for
AI features & LLM integration
Chatbots, document and data extraction, RAG, and agentic workflows. AI that does real work inside your product, not a gimmick bolted on.
Mobile development, every flavor
Native development (Swift/SwiftUI for iOS, Kotlin/Jetpack Compose for Android), cross-platform frameworks (Flutter, React Native, Kotlin Multiplatform, .NET MAUI), web-based hybrids (PWAs, Ionic/Capacitor), and low-code builders (FlutterFlow, Adalo, Glide), all shipping to the App Store and Google Play. We recommend the approach that fits your product and budget, not the one we feel like building.
App modernization & rescue
Legacy Objective-C and Java codebases brought current. Struggling apps stabilized, cleaned up, and set up to grow again.
Fractional technical leadership
Senior mobile leadership on tap (architecture reviews, team building, roadmap and vendor guidance) without the full-time hire.
(01)Discovery
We dig into your users, goals, and constraints before anyone writes a line of code.
(02)Prototype
A clickable prototype in weeks, so you can test the idea before betting the budget.
(03)Build
Short cycles, weekly walkthroughs, and working software you can hold from the first sprint.
(04)Launch
App Store and Google Play submissions handled end to end, for a clean day-one release.
(05)Support
Monitoring, updates, and new features. We stay on the team after launch.
