React Native & Expo apps for teams that need speed and stability
If mobile is core to your product or operations, you cannot waste months on indecisive builds or throwaway code. You need a cross-platform app that reaches iOS and Android quickly, feels native to users, and is something your team is still happy to work in a year from now.
BYBOWU is a web and mobile development agency based in Phoenix, AZ, working with startups and established companies across the US and internationally. This React Native & Expo track is a focused part of our broader Mobile App Development Services, built for founders and product leaders who want a fast, de-risked path from idea to live app.
Typical problems we are brought in to fix
Most clients do not call us for a blank slate. They call because something about their current approach is slow, fragile, or unclear.
- Two native teams, double the effort. Separate iOS and Android codebases, drift between features, and every minor change turning into two projects.
- Endless "MVP" work. Months of burn with nothing real in the App Store or Play Store for users, investors, or internal stakeholders to touch.
- Looks fine in simulators, breaks on real devices. Layout issues, slow lists, odd permission flows, and crashes as soon as users leave the happy path.
- No visibility once the app ships. Weak analytics, no crash reporting, and guesswork when someone asks how people actually use the app.
- Security and compliance anxiety. Sensitive data stored in the wrong place, confusing authentication, and awkward conversations with enterprise buyers.
Our job is to replace that uncertainty with a single, well-structured React Native & Expo codebase, a focused scope, and an app you are confident putting in front of customers, investors, and your own engineers.
How we build your React Native & Expo app
We move quickly, but not chaotically. You get a clear plan, visible progress, and honest tradeoffs at each step.
-
Discovery and scope alignment
We begin with the business case, not a list of screens. In the first calls we clarify why you are building this app and what "success" means for the next 3–6 months, such as investor demo, pilot with paying customers, or public launch. Together we:
- Define a focused MVP and a pragmatic roadmap for v1 and beyond.
- Call out nice-to-have features that should wait until after launch.
- Choose the right Expo workflow (managed or bare) based on integrations, performance needs, and your internal team.
-
Product, UX, and technical blueprint
Next we map what the app actually does for users and how it fits your systems:
- Screen maps and user journeys for core flows and important edge cases.
- Wireframes or clickable prototypes you can share with your team or investors.
- Decisions on navigation, state management, API contracts, offline behavior, and security basics.
When a project needs deeper UX work, we loop in our Mobile App UI/UX Design team so experience and engineering move in lockstep.
-
Rapid, incremental development
We build in focused iterations so you are reviewing the real app every week, not waiting for a big reveal at the end:
- React Native with TypeScript for predictable, maintainable code.
- Expo and EAS builds wired into CI/CD so iOS and Android binaries stay consistent.
- Over-the-air updates for safe, frequent releases without waiting on store review for every small fix.
For backend-heavy apps, we coordinate with your internal team or connect to APIs built by our Custom Software Development and Integrations & API Development groups.
-
Testing on real devices
We validate on a mix of real iPhones and Android devices so layouts, gestures, performance, push notifications, and permissions behave correctly in the real world. When projects need deeper coverage, we involve our QA & Testing Services team for structured regression, device matrix coverage, and, when needed, automation.
-
Launch, learn, and iterate
We help you navigate Apple App Store and Google Play review, wire up analytics and crash reporting from day one, and then use real usage data to plan the next sprints.
- Store listings, test tracks, and phased rollouts.
- Product analytics so you can see activation, retention, and drop-offs.
- Release cadence that fits your team and customers.
If you want a long-term partner, our Support & Maintenance services keep the app healthy while we ship improvements.
If you want a concrete plan for your app, tell us what you are building and we will respond with a draft scope, milestones, and a budget range.
What you actually get: app, codebase, and operations
You are not buying a one-off build. You are getting a product, a codebase, and an operational setup your team can work with for years.
Product and UX deliverables
- Prioritized feature list for MVP and v1, with clear in/out decisions and reasoning you can share internally.
- Screen flows and clickable prototypes for sign-off before we write production code.
- A component-based UI library so future screens stay consistent and faster to ship.
Engineering and architecture foundations
- React Native app structured with TypeScript, linting, formatting, and basic tests preconfigured.
- Expo managed or bare workflow, chosen explicitly based on your integration and performance needs.
- Modern data and state layer, such as React Query or Redux Toolkit Query, to handle caching, retries, and offline-aware behavior.
- Performance-focused implementation with list virtualization, efficient image handling, and background work off the main thread where appropriate.
- Platform-aware UX: safe areas, gestures, haptics, biometric auth, and permission flows that feel native on both iOS and Android.
Integrations and operations
- Payments and subscriptions via providers such as Stripe, Apple/Google Pay, or RevenueCat, aligned with your billing model. For more complex cases, we coordinate with our Billing & Subscriptions for SaaS Products team.
- Authentication and user management through options like Firebase, Auth0, or your custom backend.
- Analytics and monitoring tools, for example GA4, Segment, Amplitude, or Sentry, configured from the start. When projects need deeper instrumentation, we bring in Product Analytics Implementation specialists.
- Push notifications set up with sensible channels, deep links, and actions that support engagement instead of annoying users.
- Secure storage for tokens and sensitive data using platform keychain/keystore, with sane defaults for logging and error reporting.
If you also need a web admin portal or marketing site, we can connect your React Native app to Next.js frontends, Laravel APIs, and WordPress or headless CMS so one team owns the full stack.
What you can order
- React Native + Expo MVP (4–6 weeks) — A focused, investor-ready MVP shipped to TestFlight and Play Store internal testing, covering core flows, authentication, analytics, and crash reporting.
- Revenue-ready v1 mobile product — Cross-platform app with payments or subscriptions, basic offline behavior, and integrations with your existing or new backend, ready for real customers.
- Mobile companion app for your existing platform — React Native & Expo app that exposes key web or backend features on iOS and Android without rebuilding your entire system.
- Prototype + technical spike — A branded clickable prototype plus a thin working build that validates feasibility, performance, and key integrations before you commit to a full build.
- Post-launch optimization and feature sprints — Ongoing work to refine onboarding, performance, and retention using actual usage data, handled by a stable team that already knows your codebase.
Why choose BYBOWU for React Native & Expo development
- Senior ownership, not experiments. Your app is led by engineers who have shipped multiple React Native products, so choices around Expo workflow, architecture, and libraries are made with long-term stability in mind.
- Product thinking from day one. We are comfortable pushing back on scope that adds complexity without moving your metrics, and we help you phase features so you can launch, learn, and adjust quickly.
- Full-stack coverage when you need it. When the app depends on solid APIs, analytics, or marketing, our Web Development, Data Engineering & BI, and SEO & Digital Marketing teams can cover the rest.
- Predictable communication across time zones. Whether your team is local or remote, you get regular progress updates, demo builds you can share with stakeholders, and straightforward conversations about risks and tradeoffs.
- Maintainable codebases and clean handovers. We document decisions, keep dependencies sensible, and assume that your in-house team or another partner might work in this repo later.
Proof it works in the real world
Marketplace buying journeys on mobile
For fashion marketplaces similar to SixZeros and BEZET, our team has delivered lean mobile experiences that mirror key catalog and checkout flows, helping teams validate mobile behavior before investing in heavier native builds.
Companion apps for logistics and dropshipping
On wholesaler and dropshipping platforms like MonoDrop, React Native front-ends on top of existing APIs made it possible to offer mobile order tracking and catalog management without rewriting backend systems.
Matching and community-style products
For matching-focused products such as Roome, our team has shipped messaging, profile management, and onboarding flows that feel natural on both platforms, all from a shared cross-platform codebase.
How engagement and pricing usually work
Busy founders and product owners care about clarity, not vague estimates. We make scope, milestones, and costs explicit before we start.
Typical timelines
- Focused MVP: around 4–6 weeks for a tight, well-defined feature set with a clear success metric.
- Full v1 product: usually 6–10 weeks for apps that include payments, subscriptions, richer offline behavior, or more complex integrations.
Actual timelines depend on complexity, your backend stack, and how quickly decisions can be made. Before kickoff you get a written plan with milestones like UX sign-off, first internal build, beta, and public launch windows.
Engagement models
- Fixed-scope MVP builds. Best if you have a clear feature list and need something concrete for investors, pilots, or market validation on a specific schedule.
- Ongoing product partnership. A stable team that stays with you after launch to handle new features, optimization, store updates, and OS changes.
For budget expectations, you can review typical ranges on our Prices page. From there we shape a phase that fits your stage, budget, and internal team structure.
Questions founders usually ask
How do I know React Native and Expo are right for my app?
React Native and Expo are a strong fit for most product-style apps: marketplaces, booking flows, internal tools, dashboards, social feeds, and similar journeys. If you depend heavily on low-level native APIs, complex real-time graphics, or advanced 3D/AR, we will call that out early and help you weigh alternatives before you commit.
What budget range should I expect for an MVP?
Most serious MVPs with clear scope sit in a similar range to a well-built marketing site or small web app. The exact number depends on complexity, third-party integrations, and whether you also need design or backend work. We provide a written range and line items so you know what is included before you decide.
Can you work with our existing backend or in-house team?
Yes. Many clients come with an existing API or internal engineers. We are comfortable collaborating with your backend team, product managers, or designers, and can fill gaps using our own backend, integration, and UX teams where needed.
What happens after the first release?
After launch, we can either hand over the codebase with documentation and a clean transition to your team, or stay involved under a light maintenance and feature agreement. Many teams prefer ongoing involvement so we can help interpret analytics, improve retention, and keep up with OS and store changes.
Can you help if we already have a React Native app that is struggling?
Yes. If you have an existing app with performance, UX, or stability issues, our High-Performance React Native App Development & Optimization and React Native App Migration & Modernization Services can audit the codebase and create a practical plan to fix, refactor, or, if needed, phase in a cleaner implementation.
