You need iOS and Android from day one
One codebase ships both stores at once, so a new feature reaches every user in the same release.
Our AI-native team builds iOS and Android apps from one React Native and Expo codebase, takes over live React Native apps from other teams and keeps them current. New apps start from $20,000, and a focused MVP takes about 8 weeks.
One codebase for iOS and Android,
kept current after launch.
React Native development services cover everything it takes to ship one app to both stores from a single codebase: product definition, UX and UI design for iOS and Android, development in React Native with Expo, the backend, testing on real devices, release on the App Store and Google Play, and upgrades as React Native and Expo move on. Tapptitude is a React Native app development company in Cluj-Napoca, Romania. It has built 150+ web and mobile products over 13+ years and shipped React Native apps for companies in the US, the UK and Europe.

One codebase ships both stores at once, so a new feature reaches every user in the same release.
One team and one codebase cost less than two native apps, and the price stays the same on both platforms.
React Native shares TypeScript, and often logic, with a Next.js web app and a Node.js backend. Paradise Weddings runs its guest app and its wedding websites on one backend this way.
With Expo, most fixes reach users through an over-the-air update, without waiting for store review.
| Criterion | React Native | Flutter |
|---|---|---|
| Language | TypeScript, shared with React and Next.js on the web | Dart, used mostly for Flutter apps |
| UI | Native components on each platform | Its own rendering engine, the same pixels everywhere |
| Best for | Apps with a web side or a React team in-house | Pixel-identical design across platforms |
| Our projects | Paradise Weddings, Holiday Hero, Arenova | Reverse Health |
Our React Native development services are the cross-platform side of our mobile app development services. Every new app comes with its backend and admin panel, usually on Node.js, often next to a Next.js web app. We test every build on real devices, with Maestro tests of the main flows, and AI features build on our generative AI development work.
From the first workshop to both stores: product definition, design for iOS and Android, React Native and Expo development, backend and release.
From $20,000
MVP in about 8 weeks
Your developer or agency moved on and the app still needs releases. A one-week code audit, from $1,000, shows what state the code is in. Then we take over releases and maintenance.

Apps stuck on an old React Native version stop building when Apple and Google raise their requirements. We move them to the current React Native, the New Architecture and the latest Expo SDK, without stopping releases. We also maintain Ometria's open-source React Native SDK and moved it to the New Architecture.
A Next.js web app or admin panel next to the mobile app, sharing the backend and the data model.
An assistant, recommendations or insights generated from the user's own data, agreed with a clear goal before we build. Arenova writes match insights for each fan this way.
AI drafts specs, code and tests, so we move fast. People decide what to build, review every change and answer for every release.
Two or three 2-hour workshops, online or with us in Cluj. We map the business, the users and the competition, and decide what version one needs. Output: user flows and a detailed spec.
Every screen designed with your brand in Figma and linked into an interactive prototype you test with real users. Output: the scope, fixed price and timeline, in writing. You decide whether to go ahead with the build.
The first milestone is the core flow the idea depends on, so it works early. A demo call and a build you can install on iPhone and Android every two weeks. Developers work with AI coding agents that also write automated tests. Every change goes through code review.
The third milestone ends with the app live on the App Store and Google Play, with analytics and crash reporting built in and the launch KPIs we recommended set up from day one.
A monthly plan with an SLA: updates for new iOS and Android versions, critical issues answered within 4 business hours and fixed within 1 business day, above 99% crash-free sessions.

We rebuilt how we deliver around AI coding agents. The result isn't a cheaper version of the same work: it's a smaller senior team that ships more of your product, sooner, for a fixed price.
An MVP used to take six people: a product manager, an iOS and an Android developer, a full-stack developer for the backend and admin panel, a designer and a QA engineer. Today a technical product manager and a senior developer who covers both mobile and backend deliver the same scope with our product designer. Fewer people means fewer hand-offs, and it's why new apps now start from $20,000.
AI turns the notes from our definition workshops into specs and user stories. The team checks every one before it goes into the scope you sign.
Our developers build with Claude Code and Codex. Every change is reviewed by a senior developer before it is merged.
Automated tests are written with AI alongside each feature, and the team tests every build itself, so quality is part of each milestone, not a phase at the end.
Product decisions, UX and UI design and the final code review stay with people. Your code and data are never used to train AI models.
You give us access to the repository, App Store Connect, Google Play Console and the Expo account. We sign an NDA.
A code audit from $1,000: code quality, the React Native and Expo versions, dependencies, crash reports and the release setup, with an upgrade plan and the risks ranked by severity.
We move signing, certificates and the release pipeline to our team and ship the first fix release. This usually takes one to two weeks.
Maintenance with SLA from $1,500/month, with upgrades planned before they block a release. The audit fee is credited against the first month.

React Native app development at Tapptitude starts from $20,000 for a focused MVP on iOS and Android, including design, backend, an admin panel and both store releases. The price grows with the scope, and you see the fixed price for your scope after you've tested the prototype. If you already have the designs and a backend or API, the app alone starts from $15,000.
Yes. Our developers work with AI coding agents such as Claude Code and Codex, AI drafts specs from our workshops and writes automated tests, and people review every change. Because we work at a fixed price, the time AI saves goes to you: a smaller senior team, a lower starting price (new apps from $20,000) and more of your product in each milestone. We don't sell hours, so there is nothing to discount.
Every change is reviewed by a senior developer before it is merged, covered by automated tests and built on the same architecture and conventions we use on every project. Your code and data are never used to train AI models. If you want a second opinion, our one-week code audit, from $1,000, reviews any codebase, ours included.
A focused MVP takes about 8 weeks of development, in three milestones, with a demo and a build you can install every two weeks. Product definition and design come before that, under their own contract.
Yes, for most products. React Native renders real native components, and since the New Architecture its performance is close to native code. We recommend native Swift or Kotlin when the app leans on the newest platform APIs or heavy real-time graphics, and we write down why during product definition.
Yes. We start with a one-week code audit from $1,000 that also checks the React Native and Expo versions. Then we move signing, certificates and the release pipeline to our team and ship the first fix release, usually within one to two weeks. After that the app runs under a maintenance plan with an SLA, and the audit fee is credited against the first month.
Yes. The audit shows how far behind the app is and what breaks on the way. We upgrade step by step to the current React Native, the New Architecture and the latest Expo SDK, and keep shipping releases while we do it.
Yes, on new apps by default. Expo handles builds, native modules and over-the-air updates, so fixes can reach users without a store review. When an app needs custom native code, we add it as a native module and keep Expo. Read more about Expo.
Yes. Most projects run at a fixed price, but our React Native developers can also join your team to ship a roadmap you already own, with our senior code reviews behind them. More about our React Native developers.
Look for React Native apps in the stores you can try, a fixed price you see before development starts, a prototype you can test first and a plan for upgrades after launch. As a React Native development agency, we work this way: you test the prototype before we fix the price, our apps include Holiday Hero across 4,000+ listings, and every app can stay with us under an SLA.
Our team works 9:00-18:00 EET/EEST from Cluj-Napoca, Romania, which covers most of the UK and Western European working day. You get a demo call every two weeks, a shared Jira board and a dedicated Slack channel.
