Flutter & React Native Apps in the US

We are an Indian engineering team working with businesses in the US. Written scope before any code, and a fixed quote in USD.

Working hours

Our day ends at 07:30 in the US (08:30 on summer time), before yours begins, so we work asynchronously: written updates land overnight and are waiting when you start.

Quoted in USD

There is no general VAT in the US at present, so the quote is the amount you pay.

Data protection

Work for this market is scoped against state privacy law, principally the CCPA and CPRA in California, agreed before development starts rather than retrofitted afterwards.

Written scope

Every engagement starts with a written scope and a fixed USD quote within 24 hours, so the price is set before work begins.

About Flutter & React Native Apps

We build cross-platform iOS and Android apps that feel native, using Flutter when polish and 60fps animations matter, or React Native when speed-to-market and shared code with the web matters more. From MVP launches to enterprise apps with 100k+ users, we handle the full lifecycle: design, native module integration, App Store and Play Store submission, push notifications, analytics, and ongoing version updates.

What the engagement includes

  • Flutter app development (iOS + Android)
  • React Native app development (iOS + Android)
  • Native module development for platform-specific features
  • Push notifications (FCM, APNS, OneSignal, Firebase)
  • In-app purchases and subscription billing (RevenueCat, native IAP)
  • Real-time features via WebSockets or Firebase
  • Offline-first apps with sync (SQLite, WatermelonDB, Realm)
  • Maps and location services (Google Maps, Apple Maps, Mapbox)

How we work with US clients

A US engagement gets agreed twice. Once with the person who wants the thing built, and then again with legal, security, procurement and finance, who arrive separately and rarely in the same week. That second round is where a supplier outside the country loses the calendar: a master services agreement to redline, a security questionnaire, a certificate of insurance, and a vendor portal that assumes everyone it onboards can sign a W-9. Send all of it while the scope is still being written rather than in the week you wanted to start, and where the honest answer to a row is that we do not hold something, we write that in rather than leaving it blank.

You are also buying from a company you cannot drop in on, so the evidence has to do the work an office would otherwise do. What we send is live production URLs rather than a deck, a written scope with one fixed number against it, and the names of the people who will do the work rather than a bench that changes after signature. What we will also tell you is the shape of what you are hiring: a small team in Noida that has been building since 2021, not a firm that can put four more people on your project next Monday. If that is what your timeline needs, we say so before the contract rather than after it.

Indicative pricing in USD

Converted from our published Indian rates and rounded. Exchange rates move, so the figure on your quote is calculated on the day it is issued.

Questions US clients ask

Does our site have to meet ADA accessibility requirements?

If you are consumer facing in the US, build as though it does. Demand letters over inaccessible websites are routine and cheap to send, federal work brings Section 508 with it, and the Department of Justice rule under Title II sets WCAG 2.1 AA for state and local government entities on a timetable your counsel can confirm for your size band. We work to WCAG 2.2 AA and test with a screen reader rather than relying on an automated scan, because automated tools catch perhaps a third of real issues and the other two thirds are the ones that end up in a letter.

How do we know you will still be here in two years?

Nobody can promise you that, and a supplier who does is selling something. We have been building since 2021 and we maintain what we build, which is the honest version of the answer. The useful version is that it should not have to matter. The repository is in your GitHub organization, the domain and hosting accounts are in your company name, the stack is Next.js, Laravel, Flutter and Postgres rather than anything only we can read, and the handover document exists before you ask for it. If we vanished tomorrow, another agency could pick it up without needing to call us.

Can you sign our NDA and work under our MSA?

Yes to the NDA. Send your standard one and it comes back signed within 24 hours, before you describe the project in any detail. Yes to the MSA too, with the caveat that we read it properly rather than signing to be agreeable. The two clauses we usually come back on are unlimited liability, where we ask for a cap tied to the fees, and an IP clause drafted broadly enough to sweep in the internal tooling we bring to every project. Everything built for you transfers to you in full on final payment. We mark up those two and sign the rest.

Something breaks at two in the afternoon in Chicago. What actually happens?

Two in the afternoon in Chicago is past midnight here, half past midnight in summer and half past one in winter, so the truthful answer depends on what you are paying for. Monitoring does not keep our hours and the alert fires whatever the clock says. Whether a person is awake to act on it depends on your plan, because we are not a 24/7 on-call operation as standard, and we would rather tell you that while you are choosing a plan than while your checkout is down. Without out-of-hours cover written into the contract, the realistic answer is that it is picked up at the start of our day, which is the middle of your night, and you should price that in when you decide.

Flutter & React Native Apps: common questions

How much does a mobile app cost?

MVP apps (5-10 screens, basic features): $910-$1,700. Production apps (25-50 screens, real-time, payments): $1,700-$4,600. Enterprise / multi-module apps: $4,600+. Final cost depends on screen count, native module needs, and whether the backend is already built or needs to be built alongside.

Flutter or React Native, which should I choose?

Flutter wins for: visual polish, 60fps animations, identical iOS/Android look, teams comfortable with Dart. React Native wins for: faster ramp-up if your team knows React, code sharing with a web app, larger npm ecosystem. We use both, pick based on team and design needs, not framework hype.

How long does an app take to build?

MVP apps: 8-12 weeks. Production apps with backend: 12-20 weeks. Enterprise apps: 20-40 weeks. Add 2-3 weeks for App Store and Play Store review on top of dev time. We work in 2-week sprints with TestFlight / Internal Testing builds every Monday.

Will you submit the app to App Store and Play Store?

Yes. App Store submission is included in every project, App Store Connect setup, screenshots in all required device sizes, privacy policy, content rating, and the review submission. We handle App Store reviewer questions and resubmissions if anything is rejected. Play Store is straightforward and similar.

Do you offer post-launch maintenance?

Yes. Mobile apps need ongoing care, iOS and Android version updates each year, framework upgrades, dependency security patches, store policy changes. Our retainers run $230-$1,100/month depending on app complexity and feature roadmap. Most clients stay on retainer for 2+ years.
