FAQ

App development, answered

The questions founders and teams ask us before building an app.

We build consumer and business mobile apps — native iOS and Android, cross-platform apps, and internal tools — across categories like marketplaces, fintech, health, social, and AI-powered products. From MVP to scale, we handle design, engineering, and launch.

Both. We build fully native (Swift, Kotlin) when you need maximum performance and platform-specific features, and cross-platform (React Native, Flutter) when speed to market and a shared codebase matter more. We recommend the right path for your product after understanding your goals.

A focused MVP usually ships in 6–10 weeks; a full-featured product typically takes 3–5 months. Because we use senior engineers and AI-accelerated delivery, you get a fixed timeline with milestones up front, and working builds you can test throughout.

Cost depends on platforms, feature set, and integrations, so we scope each project individually rather than quoting a fixed package. Tell us what you're building and we'll send a transparent estimate with deliverables and timeline clearly defined.

Yes. We handle the full release process — store listings, assets, compliance, and submission to both the Apple App Store and Google Play — and hand over the developer accounts and code so you own everything outright.

Absolutely. After launch we offer maintenance and support plans covering OS updates, bug fixes, performance monitoring, and new features — so your app stays fast, secure, and crash-free as it grows.
