Every interaction matters. Shoppers expect retail apps to feel instant.
If the catalog stutters as they scroll, if search lags behind their thumbs, or the worst thing possible: the checkout spins one second too long... they close the app and buy somewhere else.
That's why retailers can't afford an app that slows shoppers down.
For over a decade, Infinite Red has helped retailers and e-commerce giants build fast, reliable React Native apps that customers actually enjoy using.
When your app gets out of the way, shoppers become customers.
Mercari is one of the world’s largest resale marketplaces.
Their iOS and Android teams were doubling their efforts by building features on two codebases.
Our team worked directly with the Mercari team to migrate their apps to React Native, consolidating all of the code into one codebase.
The result: a more accessible app, a unified engineering team, and the same 4.8-star App Store rating across more than 1.7 million reviews.
Infinite Red played a vital role in developing our React Native app from the ground up… We would not have successfully transitioned to React Native without their contribution. I highly recommend them for any React Native development.

Mercari is just one example. We have also helped retailers build point-of-sale systems, order management, marketplace experiences, gifting flows, and high-traffic storefronts in React Native for clients we can't publicly name
Schedule a Zoom call with usWe build in React Native, so one codebase ships to iPhone and Android and a fix reaches both at once. It’s what we’ve done for over a decade.
When something breaks mid-sale, you want the people who built the app reachable, not a ticket queue. We’re a team of about 30 people, fully remote across the U.S., and an official Expo Consultant Partner. The senior engineers who join your project write the code themselves, so a question gets answered today, not overnight. Most of our best work is under NDA. We’re used to that.
Can you migrate our native iOS and Android apps to React Native without disrupting shoppers or our app-store rating? Yes. We rewrite one screen at a time, on your release schedule, while you keep shipping. Mercari held its 4.8-star rating through the entire rebuild, from two native apps to one React Native codebase. No big-bang cutover.
Will a React Native app hold up under peak or Black Friday traffic? Yes. At commerce scale, the framework isn’t the risk. Shopify has run React Native across all its apps for five years, including its consumer Shop app, at a >99.9% crash-free session rate and sub-500ms screen loads. Mercari runs on it at marketplace scale today.
How do you handle checkout, payments, and PCI compliance? By keeping your app out of scope wherever we can. Tokenized cards and Apple Pay or Google Pay mean your app never sees the card number, so it stays clear of most PCI scope. When scope is unavoidable, we build to it deliberately.
Do you integrate with Shopify, the Storefront API, and our existing commerce stack? Yes. Shopify and the Storefront API, your search and payments providers, and the ERP and CRM you already run. We connect to what you’ve built; we don’t make you rebuild it.
Are you really US-based and senior, or do you outsource offshore? Yes, US-based and senior, with no offshore handoff. The people who scope your project are the people who write the code, and they work in your time zone. A blocker raised in the morning gets answered the same day.
Why one React Native codebase instead of two native apps? Because building every feature twice, once for iOS and once for Android, is how roadmaps stall and budgets double. One React Native codebase ships to both phones at once, and a fix lands everywhere together. Mercari unified two native teams into one this way.
Chat with our team over Zoom — one of our owners will meet you and talk through where your app is, what’s slowing the build, and whether we’re the right team to ship it. Fully remote across the U.S.
There's no perfect time to get started. Whether you have a formal proposal or a few napkin sketches, we're always happy to chat about your project at any stage of the process.
One of our owners will meet with you on Zoom to answer all your questions. Will it be Todd? Jamon? Gant? Email us and roll the dice!
