Have an app idea? Let's build it together.
Our Development
Process
A proven, transparent process from idea to App Store launch.
Discovery Call
We start with a free consultation to understand your app idea, target audience, and business goals. We help you scope the MVP and set realistic timelines.
Design & Architecture
We design the UI/UX, plan the database schema, and establish the tech stack. You get a clear picture of what will be built before a single line of code is written.
Development
We build your app using React Native, with a Supabase backend. Regular updates keep you in the loop at every milestone. Both iOS and Android are developed in parallel.
Testing & QA
Thorough testing on real devices, across iOS and Android. We test every user flow, payment path, and edge case before submitting.
App Store Launch
We handle App Store Connect and Google Play Console submissions, screenshots, metadata, and compliance review. We don't stop until your app is live.
Ongoing Support
Post-launch support for bug fixes, OS updates, and new features. We're a long-term partner, not a one-time contractor.
A Dedicated
Mobile Studio
J&H Technology LLC is a mobile app development studio focused exclusively on building high-quality iOS and Android applications. We work with entrepreneurs, small businesses, and startups to bring their app ideas to life.
We use React Native for cross-platform development, which means your app is built once and runs natively on both iOS and Android — without sacrificing performance or user experience.
Every app we build includes direct in-app purchase integration, Supabase backend, push notifications, and full App Store launch support.
