Retail apps are demanding products to build. A customer might search thousands of SKUs, switch between store and online inventory, apply loyalty rewards, pay through a digital wallet, and track an order in the same session. All of that has to work smoothly on both iOS and Android.
React Native is attractive because much of the application code can be shared across the two platforms. For cross-platform brands, that can mean fewer duplicated features and a more manageable release cycle. It does not eliminate native development, though. Payments, camera access, location services, third-party SDKs, performance-sensitive screens, and OS-specific behavior can still require native code and platform-specific testing.
The companies below were selected based on publicly documented React Native work and experience relevant to retail, ecommerce, marketplaces, or other consumer apps. We also looked for a clear reason to choose each provider, whether that is large-scale migration, product design, performance engineering, commerce integration, or the ability to supplement an existing development team.
1. SysGears — Best for Flexible Ecommerce Development
SysGears is a software development company working across mobile, web, backend, and cloud engineering. For retail and ecommerce projects, the SysGears mobile team develops React Native applications for iOS and Android, including B2C and B2B ecommerce apps, online stores, and loyalty applications.
The wider engineering scope matters when the mobile app is only one part of the system. SysGears also works with custom marketplaces, payment and order-processing integrations, ecommerce backends, and infrastructure. A company with an existing backend can keep it and build the mobile layer around the current architecture instead of treating the project as a complete rebuild.
Key strengths:
- B2C and B2B ecommerce application development
- Mobile, web, and backend engineering within one company
- Marketplace and third-party integration experience
- Full outsourcing, dedicated teams, and team augmentation
That flexibility separates SysGears from agencies built mainly around full product ownership. A retailer can outsource an application from end to end, but an established product team can also bring in additional engineers. The latter can be particularly useful when mobile commerce is already in production, and the immediate problem is development capacity rather than product discovery.
2. Studio — Best for Design-Driven Consumer Products
Studio is a New York product development company that handles strategy, branding, UX/UI, mobile engineering, and backend development. Its portfolio includes Lovelle, a live-shopping platform created for QVC, as well as work for consumer businesses such as Black Rifle Coffee.
That breadth is useful when the app itself is a major part of the customer experience. A retailer launching a new digital product may need to work through navigation, purchasing flows, visual identity, and technical architecture at the same time. Studio can cover those disciplines within one product team instead of handing a finished design to a separate engineering vendor.
Key strengths:
- Product strategy and UX/UI alongside development
- Experience with consumer-facing digital products
- Native and cross-platform mobile capabilities
- Backend engineering for products that extend beyond the app
The tradeoff is specialization. Companies that already have product managers and designers and simply need additional React Native engineers may find a product studio broader than necessary. Studio makes more sense when design and product definition are substantial parts of the engagement.
3. Infinite Red — Best for Deep React Native Expertise
Infinite Red is one of the more specialized React Native development companies in this group. It has worked with Mercari on moving its marketplace applications toward a shared React Native codebase, a useful reference point for retailers dealing with mature mobile products rather than greenfield apps.
The company is also closely involved with the React Native ecosystem. It maintains Ignite, an open-source React Native boilerplate, and organizes Chain React, a US conference dedicated to the framework. Those activities do not automatically make a consultancy better at delivering commercial software, but they do indicate sustained technical investment in the technology.
Key strengths:
- Strong specialization in React Native
- Experience with large consumer marketplaces
- Native-to-React Native migration expertise
- Active involvement in the framework’s developer ecosystem
Infinite Red is a specialist rather than a low-cost general development vendor. It is most compelling when React Native architecture, migration, or difficult framework-specific problems justify that level of expertise.
4. Netguru — Best for Omnichannel Retail Products
Netguru has a substantial retail technology portfolio, with React Native projects covering both B2C and B2B commerce.
For Sportano, a multibrand sports retailer, Netguru designed and developed a React Native shopping app for iOS and Android. Its published case study reports 5,000 installs in the first week. The company also worked with METRO BRAZIL, replacing separate native applications with a shared React Native codebase. That product had to accommodate B2B and B2C catalogs, multiple currencies, localization, and customer programs.
These are useful references because they go beyond a basic storefront. Retailers operating across countries, sales channels, or customer types tend to accumulate more complicated pricing, catalog, account, and integration requirements.
Key strengths:
- Documented React Native retail projects
- B2B and B2C commerce experience
- Product design and software engineering
- Experience with multi-market digital products
Netguru is a better fit for a retailer building a broader commerce ecosystem than for a small company looking for a narrowly scoped mobile build. Its breadth is an advantage on complex projects, but it can be more than a straightforward app requires.
5. Callstack — Best for Moving Mature Native Apps to React Native
Rebuilding an established iOS and Android product is very different from launching a new app. Callstack has particularly strong evidence in this area.
Its work with AutoZone involved migrating existing native applications toward React Native without putting regular product development on hold. According to Callstack’s case study, the migration took 18 months, while AutoZone’s mobile user base more than doubled during that period.
That detail matters. A large retailer cannot usually freeze releases for a year while engineers replace the mobile stack. Migration has to coexist with feature development, existing native modules, analytics, release schedules, and millions of real customer interactions.
Callstack has also worked with HelloFresh on React Native training. For enterprises, that type of work can be as important as writing code: an internal mobile team still needs to maintain the product after consultants leave.
Key strengths:
- Brownfield React Native migration
- Performance and architecture work
- Experience with large production applications
- Engineering training and knowledge transfer
Callstack would be excessive for many simple consumer apps. Its value becomes clearer when a company has an existing native estate, difficult performance requirements, or an internal engineering organization that needs help adopting React Native safely.
6. Nomtek — Best When Commerce Is Only Part of the App
Some retail apps are essentially digital stores. Others use commerce as one feature inside a broader product.
Nomtek’s work with Unicity falls into the second category. Its Activate app combines health and food logging with the ability to purchase Unicity products directly. The company has also developed Metals & Catalysts, where the mobile experience supports price estimation and the process of selling materials.
Neither follows the conventional browse-product-add-to-cart model. That makes Nomtek worth considering for businesses where transactions need to fit into a more specialized user journey.
Key strengths:
- React Native and product design expertise
- Experience with integrated purchasing flows
- Consumer product development
- Support for unconventional transaction models
For a standard ecommerce storefront, that specialization may offer little advantage. It becomes more relevant when a business needs to design a custom interaction around the transaction itself.
7. TELUS Digital — Best for Enterprise Customer Experiences
TELUS Digital operates on a much larger scale than a typical mobile development agency. Its work spans software engineering, customer experience, data, and AI, so it is most relevant when an app sits inside a wider enterprise digital program.
Its work for Ohio Liquor provides a concrete retail example. The React Native application incorporates product discovery, geolocation, notifications, lottery entry, as well as shopping lists that connect digital interactions with visits to physical stores.
This is the type of project where retail technology extends well beyond checkout. Personalization, customer data, store information, and mobile functionality all have to work together.
Key strengths:
- Enterprise-scale software delivery
- Customer experience and personalization capabilities
- React Native experience in retail
- Data and digital services beyond mobile development
That scale comes with an obvious tradeoff. Smaller businesses rarely need a provider with this breadth. TELUS Digital is more appropriate for enterprises where mobile is one workstream within a larger customer experience or transformation program.
8. RaftLabs — Best for Lean Consumer Apps and Marketplaces
RaftLabs occupies a different part of the market. Its React Native work covers marketplaces, loyalty products, content apps, and booking platforms, with support for features such as push notifications, deep linking, in-app purchases, and biometric authentication.
Those are practical capabilities for consumer products where retention and repeat engagement matter alongside the initial transaction.
Key strengths:
- Marketplace and consumer app development
- Cross-platform iOS and Android delivery
- Common mobile engagement features
- Product-oriented development for growing businesses
RaftLabs is particularly relevant to startups and smaller product teams that do not need an enterprise transformation partner. The narrower scope can be an advantage when the goal is to get a focused product into users’ hands without turning the project into a large consulting engagement.
9. Theodo — Best for Teams Worried About Mobile Performance
React Native makes code sharing easier, but it does not make performance problems disappear. Large image feeds, complex navigation, analytics SDKs, frequent state updates, and also poorly optimized components can still produce a sluggish app.
Theodo has an interesting position here. It has worked with React Native since 2015 and maintains Flashlight, an open-source mobile performance measurement tool. Its broader work covers product engineering across mobile and web, including applications that connect to existing digital platforms.
Key strengths:
- React Native performance engineering
- Open-source performance tooling
- Mobile and web product development
- Integration with existing software systems
Theodo is most compelling when a product team expects performance and maintainability to become serious engineering concerns. A small retail MVP with conventional functionality may not need that depth from day one.
Choosing a React Native Partner Starts With the Product You Already Have
There is no useful universal ranking of these companies. The right choice changes dramatically depending on whether a business is launching an app, replacing native applications, expanding an existing engineering team, or connecting mobile to a complex retail platform.
Start with production evidence that resembles your own problem. A generic portfolio of attractive mobile interfaces says little about a company’s ability to handle a large catalog, checkout, loyalty data, store inventory, search, payments, as well as an existing ecommerce backend. Ask what the team actually built and which parts of the architecture it owned.
For an existing iOS or Android product, migration experience deserves particular scrutiny. Moving to React Native does not mean every line of native code should be replaced. Mature applications often retain native modules or migrate feature by feature. Callstack’s AutoZone work and Infinite Red’s experience with Mercari are more relevant references here than a portfolio dominated by greenfield applications.
Performance is another area where vague claims are easy to make. Ask how the team measures startup time, rendering performance, memory use, and also responsiveness on real devices. Tools such as Theodo’s Flashlight can help, but the important point is whether the developers have a repeatable way to find bottlenecks.
The engagement model should match the internal team as well. A company without mobile engineering expertise may benefit from a studio that can handle product design through deployment. An established retailer with its own product, design, backend, and QA teams may need two experienced React Native developers rather than another management layer.
React Native can reduce duplicated work across iOS and Android, but that advantage has limits. Platform-specific code still exists, app-store requirements still differ, and complex native integrations still need engineers who understand what happens below the JavaScript layer. The best partner is therefore not the company with the longest service list. It is the one with credible experience solving the particular mobile problem the business has now.
