React Native App Development Las Vegas
One codebase for both stores
React Native app development Las Vegas owners ask about usually comes down to one question: can one build reach iPhone and Android without feeling wrong on either? I scope that answer in writing before any code is written.

React Native App Development
What a React Native build includes
React Native lets one team write an app once and ship it to both the App Store and Google Play. Most of the screens, the logic and the back end connections are shared between the two phones. The parts that touch each phone's own features, such as permissions and some device settings, are written for each platform.
The build covers the shared code, the platform-specific pieces, the test runs on both phones and two store submissions. Each part is written into the scope, so you can see which work is shared and which work is done twice.
Native Versus Cross-Platform
How to decide between one codebase and two
The honest answer depends on the app. A cross-platform build saves work when both phones run the same screens and the same logic. A native build is better when the app leans on a platform feature, a heavy graphics task or a screen that must feel exactly like the system's own.
Most owners want one build for both phones because that cuts the cost of the second one. I say so when that is true, and I say so when it is not. The decision goes into the scope with the reason, so you can see why the route was chosen.
A simple test settles most of these cases. If the app needs deep phone access, such as background location, a custom camera pipeline or a device feature that is new this year, the native route saves rework. If it is mostly forms, lists, bookings and account screens, one shared codebase keeps the cost of the second platform low.
Choosing a Build Route
The four questions that decide the route
| Question | If the answer is yes | If the answer is no |
|---|---|---|
| Do both phones need the same screens? | React Native shares most of the build | Two native builds may be cleaner |
| Does the app use heavy graphics or live video? | Native is usually the safer route | React Native is a strong fit |
| Must the screens match each phone's own look? | Native, or React Native with platform-specific screens | A shared design works well |
| Is one team and one budget for both stores? | React Native keeps one codebase to maintain | Native keeps each build separate |
React Native Cost and Scope
What moves the price of a cross-platform build
I quote a fixed price for a written scope, so the number you agree to is the number you pay. The biggest factors are the number of screens, the platform features each screen uses and the systems the app connects to. Two store submissions add review work, and the scope lists it as its own line.
A single number before the scope exists would be a guess. I write the scope first, then price each line, and I name the parts that run separately on each phone so you can see where the second store adds cost.
The scope document lists each native module, each third-party service and each store account the build depends on. Those three lists drive most of the cost and most of the schedule risk, so they come first in every quote.
Flutter Versus React Native
How I compare the two cross-platform routes
Flutter is another route for one codebase across both phones, and it is a fair choice in some projects. The scope should name the route, the reason and the person who will maintain the code, so the choice is visible to you before any build starts.
I build the route the app needs. When a team already works in React, React Native usually fits that team. When the app needs something the route cannot do well, I say so on the first call and recommend the route that does it.
Flutter draws its own interface, so the screens look the same on both phones by design. React Native uses the native controls, so the app picks up each phone's conventions. Choose the one whose trade-off matches the way the app should feel to a customer.
Testing Across Both Phones
One test list for each phone
A shared codebase still behaves differently on each phone. A button can sit in a different place, a keyboard can cover a field, and a permission prompt can appear at a different moment. Testing has to run on both phones, against the same list of tasks, so a difference is found before a customer finds it.
I keep one list for the shared screens and a second list for the platform pieces. Each result is recorded with the phone model, the operating system version and the fix, and a failed test stays open until it passes on both phones. The lists go into the scope, so you can see what was tested before either store sees the build.
Test runs start with the screens people use most: sign-in, the main list, the booking or payment form, and the notification that brings them back. Defects are ranked by how many users they would block, so the first fix is always the most important.
React Native App Developer
Who builds the shared code
The same person who scopes the app writes the shared code and the platform pieces, then tests both phones. Each phone gets its own test list, with the result recorded for you to read before either store submission.
Shared screens
The screens and logic that both phones use, written once and tested on each device.
Platform pieces
Permissions, notifications and device features that differ between the two phones, written for each one.
Two store submissions
Each store's listing, privacy answers and review notes, prepared and sent separately.
React Native Development Process
Four steps from scope to both stores
Each step ends with a result you can open or approve, and the store steps come last, after both phones pass the tests.
- Step 01
Scope the first version
I list the core tasks, the screens they need and the platform features each one uses, then you approve the list in writing.
- Step 02
Prototype the flow
I build a clickable version for your phone so you can walk through each task before the build starts.
- Step 03
Build and test on both phones
I build the shared code, add the platform pieces and run every task on iPhone and Android, recording each result.
- Step 04
Submit to both stores
I prepare both submissions, send them and answer any review question on the day it arrives.

GIOSTAR: the clinic website, booking and lead tracking
I built and run giostarwellness.com for a regenerative medicine and wellness clinic in Henderson: every service page, online booking, financing and a blog. A website lead is tracked end to end, from the form to a booked consult to an active patient, with no manual steps. I also built its live brand hub, so every page, post and print piece pulls the same colours, type and rules.

After going back and forth on whether to bring in outside help, we ended up working with Justin for some AI consulting on how to structure our operations. He laid out a clear plan, didn't overcomplicate it, and we've been running smoother since. Good fit for a service business. He knows Las Vegas and he knows this stuff.

Justin joined our team a few months before opening to replace a marketing agency that wasn’t performing. He stepped up fast. Within weeks he launched a fully redesigned website with new brand guidelines, built and delivered our marketing plan and AI strategy, and helped implement our system architecture so we could open on time. Since then, he’s made several critical enhancements to the site that helped us generate revenue in our first month. His engagement was supposed to end at opening, but he became such an integral part of our leadership team that we kept him on to help evolve our marketing and tech strategy as we grow. He’s easy to work with, pushes back when it matters, and moves easily between strategy, delivery, and operations depending on what’s needed. If you’re looking for a deeply experienced, knowledgeable, and dedicated marketing, AI, or technology consultant, I highly recommend Justin Harris AI Consulting.

Shipping and Updating a Cross-Platform App
One codebase, two release tracks
A cross-platform app still ships two binaries, and each store updates on its own clock. Apple and Google review builds against their own rules, and a library that passed last quarter can fail review this month. I handle that by pinning versions, keeping a changelog for every native module and testing the release candidate on a real iPhone and a real Android phone before it goes to review.
Small JavaScript fixes can reach users faster than a full store review when the app is set up for it. Anything that touches native code still goes through the store. I label each release by its path, so the cost and the wait for a fix are clear before the work starts.
