Custom React Native apps that ship, scale, and actually get used
If you are funding a mobile app, you are not buying screens. You are buying signups, orders, and retention. The tech stack matters, but what matters more is that you get a stable product in the App Store and Google Play that your customers want to open again tomorrow.
BYBOWU is a senior web and mobile team focused on React Native and Expo for startups and enterprises across the US and internationally. We design and build cross-platform apps that share one codebase, plug cleanly into your backend, and are maintainable long after the first release.

The problems we are usually brought in to fix
Most mobile projects do not fail because React Native or Expo are the wrong choice. They fail because goals, ownership, and architecture are fuzzy from day one. If any of this sounds familiar, you are not alone:
- Two native apps, double the headache: Separate iOS and Android codebases, duplicated bugs, and slow feature rollout.
- Inconsistent UX and flows: Different signup or checkout journeys per platform, confused users, and extra support tickets.
- Architecture debt from the first sprint: Ad-hoc state management, unclear API contracts, and brittle integrations that break on every release.
- Beautiful UI, weak business impact: Apps that look good in a demo but do little for activation, repeat orders, or retention.
- Stressful releases: Manual builds, last-minute store rejections, and a team that is nervous every time you submit an update.
Our React Native work is set up to avoid these traps early so your team spends time growing the product instead of firefighting.
How we build your React Native or Expo app
We treat mobile as a core product line, not a side quest under your web roadmap. The process is structured, but not heavy.
-
Discovery and product definition
We start with your business model and where mobile fits. Who will use the app, what are their jobs to be done, and which metrics matter in the first 3–6 months. Together we define a focused MVP: core use cases, must-have flows (onboarding, authentication, ordering, booking, messaging), and nice-to-haves that can wait for phase 2.
-
UX, UI, and technical architecture
Our design team maps user journeys, then we build clickable prototypes so stakeholders can feel the flows before we write production code. In parallel, we design the architecture: navigation, state management, API contracts, and how the app will authenticate, cache, and sync data online and offline when needed. When a deeper design pass is useful, we involve our Mobile App UI/UX Design team.
-
React Native and Expo development
We implement a single, shared codebase for iOS and Android using React Native, with Expo or bare React Native depending on your needs and future plans. Typical implementation details include:
- Reusable, well-typed components and screens with consistent behavior across devices.
- Predictable navigation patterns (stacks, tabs, modals, deep links) with clear state handling.
- Offline-aware data flows for users who are on the move or in low-connectivity environments.
- Clean integrations with your backend, payments, analytics, CRM, or other third-party services. When needed, we involve our Integrations & API Development team.
-
QA, performance, and analytics
Before anything reaches the stores, we test core flows across iOS and Android devices, validate edge cases, and check performance where users feel it most: startup time, scroll and tap responsiveness, and network calls. Our QA & Testing Services team can extend this with structured manual and automated testing when your risk profile calls for it. We wire in analytics, crash reporting, and basic funnels so you see real behavior from day one.
-
Launch, monitoring, and iteration
We guide you through App Store and Google Play submissions, set up CI/CD and over-the-air updates, and monitor real-world performance and crashes just after launch. From there, we help you choose improvements that actually move metrics, not just add features that are nice to demo.

What you actually get as deliverables
A React Native or Expo engagement with BYBOWU is not a black box. You get concrete assets your team can build on.
- Production-ready iOS and Android apps built from a single, well-structured React Native codebase.
- Clear, documented user flows for onboarding, authentication, payments, search, booking, messaging, or other core actions.
- Backend and API integrations with your existing systems, whether that is a custom Laravel backend, ecommerce platform, CRM, or internal tools. When required, we coordinate with our Custom Software Development and DevOps & Cloud Engineering teams.
- CI/CD pipelines so builds, tests, and store submissions are routine, not a manual scramble on release day.
- Over-the-air (OTA) update workflows so you can push minor fixes and UX improvements without waiting on a full store review each time.
- Analytics and observability with events, funnels, crash reports, and performance metrics wired in from launch.
- Documentation and handover so your internal engineers or future partners can take over without digging through guesswork.
If you already have a web product, we align the mobile app with your existing design system and backend so you do not pay twice to solve the same problems.
What you can order
- MVP React Native launch — A focused React Native or Expo app with the essential flows ready for App Store and Google Play, ideal for validating a new product or feature. Often paired with our Startup MVP Development offers.
- React Native ecommerce app — A mobile storefront connected to your existing ecommerce platform or custom backend, with optimized browsing, cart, and checkout. When relevant, we coordinate with our React Native E‑commerce Mobile App Development and E-commerce Development services.
- Customer portal or booking app — A secure React Native app for bookings, account management, and notifications, integrated with your current scheduling or internal systems. Related to our Booking & Delivery Platform Development work.
- React Native app modernization — Code audit, refactor, and cleanup for an existing React Native or Expo app so you can ship features again with confidence. When suitable, we use our React Native App Migration & Modernization packages.
- High-performance optimization — Targeted engagement to improve startup time, navigation responsiveness, and bundle size. Often aligned with High-Performance React Native App Development & Optimization.
- Continuous product development — A dedicated team to handle ongoing feature delivery, experiments, and maintenance for an app that is already in market, supported by our React Native Mobile App Maintenance & Support services.
Why choose BYBOWU for React Native development
- Senior product and engineering attention — You work with people who can speak both business and tech and will be direct about tradeoffs, scope, and when a feature can safely wait for a later phase.
- Product thinking baked in — We do more than close tickets. We help simplify flows, cut low-value features, and focus on what will move activation, retention, and revenue in the next release.
- Web and backend depth — Our work across modern web apps, Laravel backends, and React/Next.js frontends means your mobile app fits neatly into the broader stack instead of becoming a silo.
- Clear communication with distributed teams — Experienced leadership, pragmatic documentation, and regular demos keep stakeholders aligned whether your team is in the US or abroad.
- Built for the next phases, not just launch — We design architecture, testing, and release workflows so you can keep shipping safely, with or without us on the team.
Proof it works in the real world
Fashion marketplace on mobile
For a modern clothing marketplace, we implemented web and mobile experiences with fast catalog browsing and smooth checkout, giving their team a unified base to extend into full mobile commerce. See project overview.
Tactical ecommerce experience
We helped a tactical apparel marketplace structure product data and navigation so shoppers can easily filter, compare, and buy from mobile devices, turning niche visitors into repeat customers. See project overview.
Roommate matching flows
For a roommate discovery platform, we designed and built flows that collect preferences, run matching logic, and guide users through onboarding with less friction and fewer support requests. See project overview.
Automation tools tied into mobile
On internal tools and bot projects, we connected automation logic to simple mobile and web interfaces so teams could trigger workflows and review results without needing a desktop. See example work.

How engagement works
You are busy, so we keep the collaboration simple and predictable.
- 1. Quick intro call — We talk through goals, current assets (designs, APIs, existing apps), timelines, and constraints. If there is a fit, we move into a short discovery.
- 2. Scope and estimate — You get a clear proposal with scope options, phases, and budget ranges, usually within one business day after we understand the essentials. Typical ranges are outlined on our Prices page.
- 3. Build in focused sprints — We work in small, transparent iterations, show progress regularly, and keep you out of implementation details unless you want to dive in.
- 4. Launch and measure — We handle store submissions, validate analytics and crash reporting, and help you read early data so you can adjust roadmap priorities.
- 5. Iterate or hand over — We can stay on as your mobile product partner through our Support & Maintenance offers, or we can hand over to your internal team with documentation and training.
If your team likes in-person workshops, we can plan working sessions locally. If you are distributed across the US or abroad, we run everything smoothly over video and async tools.
Questions founders usually ask
Do you use Expo or bare React Native?
Both. We use Expo when it speeds up delivery, simplifies updates, and fits your long-term needs. We switch to bare React Native when you need deeper native modules, custom integrations, or more control over the build pipeline. We walk you through the tradeoffs before committing to one path.
Can you extend or rescue our existing React Native app?
Yes. We start with a code and architecture review, highlight risks and quick wins, then either stabilize what you have or plan a staged refactor. The goal is to get you back to shipping without throwing away proven parts of the product.
What timelines should we expect?
As a rough guide, a focused MVP often takes 6–12 weeks, a more complex app with multiple flows and integrations can run 12–20 weeks, and ongoing product work continues in monthly or quarterly cycles. We confirm timelines and milestones with you once we understand scope and dependencies.
What kind of budget do we need?
Simple MVPs with a small set of core screens and flows usually start in the tens of thousands of dollars. Larger builds with complex logic, third-party integrations, and analytics stacks scale from there. If you share a rough range, we can quickly tell you what is realistic within it and how to phase work if needed.
Can you integrate the app with our current backend or web platform?
Yes. A large part of our work is connecting mobile apps to existing systems like custom APIs, ecommerce platforms, CRMs, booking engines, or internal tools. We collaborate with your team on API design, authentication, rate limits, and data contracts so the integration stays stable over time.
What happens after launch?
You are not left alone with a Git repo. We offer maintenance and improvement plans that cover updates, monitoring, and new feature delivery, or we prepare your internal team to take full ownership with documentation and optional training sessions.
If you are evaluating React Native and Expo for your next mobile app and want a straightforward conversation about options, tradeoffs, and realistic scope, we are happy to talk.
