Shipped & live

One codebase, two app stores

React Native lets one codebase run natively on both iOS and Android, so you launch on both platforms for less than the cost of two separate apps, and every future update ships to both at once.

I handle the whole product, not only the screens: the backend API, data model, auth, push notifications, payments or subscriptions, and the store release process.

  • Consumer apps with accounts, wallets, and payments
  • Offline-first apps that sync when connectivity returns
  • Booking and on-demand service apps
  • Companion admin dashboards for your team
  • Google Play and App Store release

HOW IT WORKS

From call
to launch.

  1. Step 01

    Free 15-min call

    Tell me your idea. You leave with a rough scope, a realistic timeline, and a budget range.

  2. Step 02

    Scope & fixed quote

    I turn features and screens into a written scope with one fixed price. No hourly billing, no surprise invoices.

  3. Step 03

    Build with demos

    You see working software as it’s built, so feedback happens early instead of at the end.

  4. Step 04

    Launch & handover

    I ship it to production and hand over the code, deployments, and accounts, so you own all of it. Then I stay on for a month of free support.

FAQ

Common
questions.

How much does it cost to build a mobile app in the Philippines?

My mobile app projects are fixed price, starting at $7,900 for an iOS and Android app with a backend API, auth, payments, and store release. The exact price depends on features, and you get a fixed quote after scoping.

Do you build native apps or React Native?

React Native. It renders real native components, so the app looks and feels native on both platforms, and for most startups it’s faster and more affordable than two separate native apps.

Can you publish the app to Google Play and the App Store?

Yes. Store release is included: builds, listings, and the submission process. Your app is published under your own developer accounts, so you keep full ownership.

Do you also build the backend?

Yes, it’s part of every mobile build, so you get one complete product instead of an app waiting on someone else’s API.
