Ronas IT is an Estonia-based engineering team. Since 2020, we've shipped 20+ React Native apps for fintech, marketplaces, logistics, and other sectors. We bill you directly, with no resellers involved. Send us 4 lines about your ideas and get a response within 24h with a rough estimate, or book a free call that takes 30 min.
Sometimes after a round of store-review iteration.
Most of our 20+ React Native apps are under NDA, so you won't see every store badge here. Two public ones to open right now:
Lainappi provides boxes to help people give and take any items for rent, requiring a mobile app to connect the sharers.
OddsCrowd is a web platform that collects information on sport games, providing sport bettors with the latest updates.
React Native covers almost everything your app needs — our in-house React Native team has used it for products with deep linking, push notifications, analytics, chats, live data updates, and store releases.
If it's not the right call, we say so on the discovery call. We've passed on heavy-graphics gaming, deep AR/VR, and ultra-low-latency networking work. On OddsCrowd, we swapped two of three odds providers mid-project without rewriting to native.
We use React Native when it's the right tool, not because it's the default. Here's when it fits, when we add native code on top, and when we recommend pure native instead.
React Native is a strong fit when most of the code can stay shared across iOS and Android. Although a few features still need direct access to platform APIs, most "React Native can't handle this" concerns are outdated. When a feature needs native code, our React Native team writes it and connects it to the shared codebase. That's usually 5-15% of the scope; the main product stays cross-platform.
We can add native modules to cover almost any core platform feature:
Three exceptions when we recommend pure native instead:
Heavy 3D graphics or game-level rendering, where Unity, Unreal, Metal, or Vulkan is a better fit.
Companion apps for Apple Watch or Wear OS. React Native doesn't run on the watches. We build these parts separately in Swift or Kotlin and connect them to the main product when needed.
Products where microsecond-level latency is critical, such as high-frequency trading or multiplayer apps with a custom networking stack.
Every estimate is a full price: design, project management, testing, and the backend your app needs are already included.
A minimal MVP takes 4-6 weeks. A full launch usually takes 12-20 weeks, depending on scope.
You can keep adding features, switch to maintenance from $1,000 per month, or request a full handover at any time.
One PM manages delivery, while you keep direct access to designers, developers, and DevOps in ClickUp. Every decision is documented as a verifiable project artifact, so agreements don’t stay verbal and can be checked against the final release.
You own 100% of project assets from day one: the code, infrastructure, Figma files, documentation, and repositories. They live in your accounts, or in ours with full access and transfer whenever you ask.
We keep at least four working hours of overlap with your team and adjust our schedule when needed.
No mid-project engineer rotation, no juniors-to-seniors handoff. One stable team of senior mobile engineers, in-house DevOps, and multi-layer QA support the project throughout.
We handle app assets, submission, review responses, and rejection fixes for App Store and Google Play.
We use our Apple and Google Play accounts first; you register yours before production release.
PostgreSQL or MongoDB, Redis, and a Kubernetes-ready backend let you grow from 1k to 100k+ MAU without rewriting your backend when your React Native app scales.
Expo Updates lets us ship eligible fixes over the air within hours instead of waiting days for store review.
We might not be the fit for you if:
You need pure outstaffing, where engineers slot directly into your team's daily management. We sell managed delivery with our PM, QA, and tech lead in the loop.
Procurement requires a 6-month pre-contract cycle with multiple vetting layers. We work best with founder-led teams that can decide within 2-3 calls.
You expect us to start building without any discovery or alignment step. We need at least a short discovery to check fit and shape scope. We don't ship blind.
The lowest price is your single deciding factor. Our prices cover a managed team with senior React Native engineers and project management; teams without that layer can legitimately quote lower.
If your project falls in the wrong-call list, we'll say so on the discovery call.
1,285 accounts opened by verified users · historical App Store approval
Neobank app for the US market, built with 7 microservices, 8 third-party SDKs, KYC, card issuing, direct deposits, cashback, and secure financial data flows. During onboarding, Sardine tracked field interactions, while Persona handled document checks. If a user left the flow, the app resumed at the relevant KYC review or retry step.

React Native fitness app with AI-driven recommendations and Laravel Nova on the backend. A clear example of embedded AI in a consumer wellness product.
We check the idea holds up before writing any code, and each stage produces a concrete result you can use. Testing and release preparation run alongside development, so the stage durations below are not meant to be added up.
30 minutes · free
We discuss your product idea, goals, and stage. Then we check React Native fit, outline a rough budget and timeline, and confirm team availability for the next 3 months.
1 week · paid, $1–2k
The product idea becomes a delivery plan: user stories, main flows, technical and product risks, and a sharper estimate. You also get portable materials to use with our team or share with another vendor.
1-2 weeks
Before development starts, we create a design concept, map the connections between screens, and prepare full-color UI design flow by flow. If needed, we can also prepare a clickable prototype. In parallel, we define the technical architecture: how the product will be structured, what integrations it may require, and which technical constraints can affect the interface. After this stage, we refine the development estimate.
2-3 weeks for a basic MVP · 8-14 weeks for a standard or full MVP
We build the MVP in milestones, so you can see progress early and adjust the scope if needed. After each milestone, you get a working build, a demo, a weekly report with completed tasks, planned work, and risks, plus an updated estimate for the next stage.
about 1 week
We test the app on real iOS and Android devices, prepare store assets, and get the production build ready. This includes testing reports, screenshots, descriptions, app preview videos, and App Store and Google Play submission.
flexible cadence after release
The same PM and engineers continue. Cadence and engagement format adapt to your stage (see Pricing for options); a structured 2-4 week handover is available if you move in-house.
Analysis is where we reduce project risk before it turns into expensive rework. A small clarification may take 20-30 minutes during analysis, several hours during design, and days or weeks during development. We use this phase to catch "that's not what I meant" moments before they turn into engineering rework.
Before development starts, we make the technical decisions that affect cost, timeline, release speed, and long-term maintainability: native fallback boundaries (BLE, payment SDKs, OS-level integrations), Expo workflow, OTA update strategy, and iOS/Android parity (ATT, background limits).
We also identify React Native-specific risks: App Store and Google Play policy constraints (ATT, IDFA, In-App Purchase, Data Safety, Play Integrity), Expo and React Native upgrade windows, third-party library compatibility, native module limits, and compliance requirements such as GDPR, CCPA, PCI DSS, PSD2/PSD3, DORA, or health-data regulations.
Once we understand the product, industry, risks, and technical requirements, we assign people with relevant experience in your domain — fintech, real-time, native modules, whatever your project requires.
For projects starting at $40k, our CEO Roman Surikov can join the analysis phase to discuss product decisions and fit; for smaller MVPs, a call with him can be arranged on request.
A portable project foundation: user stories, main user flow maps, a risk register, React Native fit assessment, rough architecture direction, and a sharper budget and timeline estimate.
The artifact stands on its own as independent documentation any team could build from. If you're coming from a non-technical field and a wireframe communicates better than a written flow, we bring design into this phase too.
Avg cost to make changes
React Native is not just one of the technologies we offer. It is a dedicated engineering practice inside Ronas IT, with its own toolchain, open-source projects, and senior technical leads.
This means your production app is built by in-house engineers with deep React Native experience, not subcontractors.
— a production-grade React Native app for self-hosted AI assistants. A real open-source example of our production RN code.
— shared modules we use across our React Native projects.
— hooks and helpers for Clerk authentication in React Native and Expo apps.
— Nx generators for monorepos with Next.js and React Native apps, built for teams that share TypeScript code between web and mobile.
— wrapper utilities for CRUD operations with REST APIs through RTK Query, used in our React Native frontends.
Scrumban for most projects. Waterfall only when scope is fixed up front.
MoSCoW prioritization in presale to fit scope to budget.
Monthly milestone demos plus weekly informal check-ins.
Weekly reports. What shipped, what's planned next, what risks we see.

Testing on real iOS and Android devices, not only emulators
We evaluate 400+ technologies in our internal Tech Radar, and React Native is marked as Adopt — our highest confidence level for production-ready tools. The verdict is based on maturity, maintainability, team expertise, and project risk.
We don't leave testing to a single final QA pass. Automated tests (unit, integration, E2E with Maestro, PHPUnit) run inside layers 1-2 and gate every commit. On top, each feature goes through several human review checks before release.
Testing layers
Our React Native development services are flexible depending on your stage, scope, and budget. You can start with the analysis phase, build a fixed-scope MVP, or extend the team for ongoing product development.
Our MVP offers are structured around the stage of your product, from first validation to a full launch-ready build. Design, tech stack, testing, and launch are the same on every project — the tiers below show how the product scope changes.

Numbers
We can continue supporting the product after release without restarting the collaboration from scratch. During active iteration, we usually work in weekly sprints. Once the product stabilizes, we can switch to lighter maintenance. Post-launch support can include new features, bug fixes, store policy updates, React Native and Expo SDK upgrades, infrastructure monitoring, and security updates.
New features are estimated separately or planned as sprints. Maintenance — monitoring, bug fixes, OS and SDK updates, and store-compliance releases — runs on a subscription from $1,000/month with predictable scope. If you later build an in-house team, we can run a 2–4 week structured handoff with documentation, deployment runbooks, and knowledge transfer.
It depends on your team and project. React Native is our default, and we also build in Flutter: if your team already works in Dart or Flutter is your company standard, we build the app in Flutter so it stays in the stack your developers will keep working with.
Practical decision factors:
If your team already uses React or wants to share TypeScript across web and mobile, React Native is usually the stronger choice for cross-platform app development.
Send us four lines: project idea, target platforms, budget range, timeline. We'll come back with a rough estimate within 24 hours.
100% of our React Native projects have launched to both stores. Sometimes after a round of store-review iteration.
