Custom Mobile Apps Built to Survive Their Second Year
Most mobile projects don’t fail at launch. They fail eighteen months later, when the codebase can’t take another feature and every fix breaks two other things. Sigosoft builds custom mobile apps that hold up well past that point, for startups shipping a first product and for enterprises replacing internal systems that stopped keeping up.
We work in Kotlin and Swift when an app needs full native performance and deep hardware access, and in Flutter when one codebase across Android and iOS is the smarter call. That decision gets made against your actual requirements, not a house preference. Every build follows ISO/IEC 27001:2022 aligned security and development standards, so access control, encrypted communication, and secure coding are part of the work rather than a checklist at the end.
We stay involved across the whole arc: validating the idea, designing the interface, building, releasing to the App Store and Play Store, then handling the updates and fixes that arrive once real users do. A concept becomes a product people keep on their phones and open more than once.
What we build:
-
Native Android and iOS apps in Kotlin and Swift, tuned for speed and offline use
-
Cross-platform Flutter apps from a single codebase, without the native feel getting lost
-
Enterprise mobile systems with role-based access, audit trails, and reporting
-
API and cloud integration across REST, GraphQL, AWS, and Firebase
-
Architecture designed so new features slot in instead of forcing a rewrite
Not sure whether your project needs native or cross-platform? That’s usually the first thing worth settling, and we’ll talk it through in a free scoping call before any code gets written.
