Mobile app development for teams that care about product, not just code
Your users do not care what your app is built with. They care that it opens quickly, never loses their data, and helps them get something done. BYBOWU is a Phoenix-based, globally focused team that designs and builds mobile apps for founders, product leaders, and operators who need a partner that thinks about the whole product, not only the sprint backlog.
We work across React Native, Expo, Flutter, and native Swift / Kotlin to ship apps that are stable, measurable, and ready to grow with your business in the US and worldwide.
The problems we solve
If any of these sound familiar, you are in the right place:
- You have an idea or early MVP, but no clear roadmap to a reliable V1 your stakeholders can trust.
- Your existing app is slow, buggy, or expensive to maintain, and each release feels risky.
- Your team is strong on marketing or operations but needs senior technical leadership to make good platform and stack decisions.
- You need to launch on both iOS and Android without doubling cost and complexity.
- You are trying to tie mobile into your web platform, CRM, ecommerce, or back office systems and do not want a fragile integration.
Our job is to de-risk the build, focus the scope, and get you to a version of the product that actually moves numbers: signups, orders, bookings, or completed workflows.
How we approach mobile app development
We work in clear, visible phases so you know what you are getting and when.
1. Discovery and product strategy
We start with short, focused sessions to understand your business model, user segments, and constraints. Together we define:
- Key use cases and user journeys that must work flawlessly at launch.
- The smallest viable feature set for MVP, V1, and later phases.
- Technical choices: React Native / Expo, Flutter, or native, and how the app will talk to your backend or third-party systems.
By the end of this phase, you have a written scope, high-level architecture, and an initial release plan that fits your budget and deadlines.
2. UX / UI design and prototyping
Your app needs to feel obvious on first use. Our designers map onboarding, navigation, and core actions, then create interactive prototypes so you can click through the experience before a single screen is implemented.
- Wireframes for core flows and edge cases.
- Platform-appropriate patterns for iOS and Android so the app feels "right" to each user.
- Design assets and component libraries that developers can work with efficiently.
3. Development and integrations
Once designs are locked, our engineers implement them using the stack that best fits your roadmap:
- React Native and Expo for most cross-platform apps where shared code and fast iteration matter. Explore React Native development.
- Flutter when you need highly polished UI and consistent behavior across devices.
- Swift and Kotlin when low-level platform features or very specific performance needs make native the right choice.
We connect your app to existing or new backends, including Laravel APIs, Node or Django services, and SaaS products such as payment gateways, CRM, analytics, messaging, and authentication providers.
4. Quality assurance and real-device testing
Before anything reaches the App Store or Google Play, we run structured QA and real-device checks:
- Functional testing of all main and alternative flows.
- Performance and battery impact checks on a mix of devices and OS versions.
- Offline and weak-network behavior where it matters for your users.
- App Store and Google Play policy checks so you clear review faster.
5. Launch and ongoing improvement
We set up build pipelines, handle store submissions, and help you roll out releases safely, from internal testing to staged rollouts. After launch, we keep an eye on crash logs, performance, and behavior analytics so we can prioritize improvements that have the most impact.
What you can order
- Mobile MVP build — focused iOS and Android app that covers your core use cases, with analytics and basic release pipeline, in weeks not months.
- V1 product launch — full app with onboarding, payments or subscriptions, notifications, and integrations with your existing web or backend systems.
- App modernization and migration — stabilize or rebuild a legacy app in React Native, Expo, Flutter, or native, reduce crash rates, and simplify future releases.
- Performance and UX optimization — audit your current app, fix bottlenecks, refine flows, and improve ratings and retention without a full rebuild.
- Ongoing maintenance and releases — monthly retainers for OS and library updates, bug fixing, release management, and continuous UX improvements.
- Mobile + web platform bundle — coordinated build of your app plus a web dashboard or admin, using Laravel, React, or Next.js where needed. See web development services.

Proof it works in the real world
Wholesale operations in your pocket
For a wholesaler and dropshipping platform, we paired a Laravel backend with a React Native app so merchants could manage orders and inventory from their phones. The result was a smoother order flow and less time spent on manual updates.
Matching people, not just profiles
We helped a housing marketplace evolve from idea to functional product, connecting web and mobile so users could find and chat with potential housemates seamlessly across devices.
From catalog to owned audience
For fashion and tactical clothing brands, we supported mobile-first user experiences that made browsing, wishlists, and repeat purchases feel effortless, building on top of existing ecommerce infrastructure.
How engagement works
We keep the collaboration simple and transparent so you can focus on decisions, not process.
- Step 1: Quick call and review — you share where you are (idea, MVP, live app) and your priorities. We discuss scope, risks, and constraints.
- Step 2: 24-hour estimate — within one business day, you get an initial plan, tech stack recommendation, and a budget range. For complex products, we may suggest a short paid discovery to get the details right.
- Step 3: Discovery and design — we refine requirements, craft the UX / UI, and lock the first release scope.
- Step 4: Build, test, release — we develop in short iterations, show progress frequently, then guide you through store approvals and rollout.
- Step 5: Support and growth — you can keep us on for maintenance, optimization, and new features under a clear retainer or scoped projects.
Questions founders usually ask
How much does a mobile app project typically cost?
Budgets vary a lot depending on scope, integrations, and platform choices. A focused MVP with a few core flows is often in the lower five figures, while complex, multi-role apps with payments, heavy integrations, and admin panels are higher. After a short call and basic requirements, we can usually provide a realistic range within 24 hours.
How long will it take to launch the first version?
For a lean MVP with clearly defined flows, we usually see 4–6 weeks to a testable build and 6–10 weeks to a store-ready release. Feature-rich V1 products with more integrations can run 8–12 or more weeks. We agree on milestones and timelines together before we start.
Should we use React Native, Flutter, or go fully native?
It depends on your roadmap and constraints. We often recommend React Native or Flutter when you need to move quickly across iOS and Android with one team. Native Swift / Kotlin can be better for apps with very specific platform integrations or performance requirements. We will walk you through tradeoffs so the choice matches your product, not our favorite tool.
Can you work with our existing backend and web team?
Yes. We regularly integrate with existing Laravel, Node, Django, or other APIs and collaborate with in-house or other vendors. If you do not have a backend yet, our team can design and build it as part of the engagement. See custom software development.
What happens after launch? Do you provide maintenance?
We offer structured maintenance that covers OS and library updates, security patches, bug fixes, monitoring, and small improvements. You can also book us for new feature work as your product and user base grow. Explore support and maintenance.
Can you help us with ASO and user acquisition?
We make sure your app is technically ready for App Store and Google Play search and tracking from day one. For broader acquisition, we can coordinate with our SEO and advertising teams or your existing marketing partners. See SEO and digital marketing services.
