From idea to App Store in weeks
A proven, agile process that keeps you in the loop at every step.
Discovery & Scoping
We understand your idea, audience, and goals. Then scope features, choose the right tech stack, and map out an MVP roadmap.
UX Design & Prototype
User flows, wireframes, and high-fidelity Figma designs following platform guidelines. Interactive prototype for your sign-off before a single line of code.
Agile Development
2-week sprints with working builds delivered to you via TestFlight or Firebase App Distribution — test the real app at every stage.
Testing & QA
Manual and automated testing across devices, OS versions, and edge cases. Performance, security, and crash-rate benchmarks before submission.

Common questions
Should I build native or cross-platform?
For most startups and businesses, React Native or Flutter is the right choice — you get both iOS and Android at 60–70% of the cost of two native apps, with near-native performance. We'll recommend the right approach after learning your requirements.
How long does it take to build a mobile app?
An MVP app takes 8–12 weeks. A full-featured app for both platforms typically takes 12–20 weeks. Complex enterprise apps can take 20+ weeks. We always start with a scoping session to give you a precise timeline.
Do you handle App Store and Play Store submission?
Yes — completely. We handle screenshots, app previews, metadata, keyword optimization, and the full review process for both Apple App Store and Google Play Store. ASO is included in every launch package.
Will I own the source code?
100%. Upon final payment, you receive full ownership of all source code, assets, and documentation. We hand over the complete GitHub/GitLab repository. No lock-in whatsoever.
Can you build the backend and API as well?
Yes — we have a full-stack team. We build scalable Node.js and Python backends with REST or GraphQL APIs, cloud infrastructure on AWS, real-time features, push notifications, and everything your app needs server-side.
