React Native or Flutter: which should we choose?

React Native if you already have a React web team or a JavaScript ecosystem. Flutter if complex animations and maximum UI performance are the priority. For 80% of product tasks, the difference is negligible. On the first call we'll look at your situation and give you a specific recommendation in 30 minutes.

Will the app be as fast as a native one?

Yes. React Native and Flutter deliver native speed for 95% of tasks; the performance difference is statistically insignificant. For resource-heavy scenarios (AR, video processing, 3D graphics) we plug in native Swift/Kotlin modules. 60 fps is our standard, not the exception.

How much does it cost, and how long will it take?

It's a ladder, not a single price: a clickable prototype is free in 5 days, before any contract. An MVP core with 1–2 key scenarios, published in the stores: from $9,900 in 6–8 weeks. A full app with sign-in, payments and push notifications: $35–90K, 3–5 months depending on scope. A detailed quote comes 3–5 days after the Discovery session and is fixed in the contract.

We run a fitness club or a salon. Why not a ready-made white-label app?

If standard scenarios are enough, go white-label: it's cheaper at the start, and we'll tell you so in the consultation. Custom pays off when the app is part of your brand: your own store listing and your own customer base (not the platform's), your own scenarios and integration with your CRM or accounting system, your own push notifications and analytics. Two years of monthly platform fees add up to a real sum with no asset at the end, while an MVP core from $9,900 stays yours.

Do you help with publishing to the App Store and Google Play?

We handle it completely: screenshots, descriptions, ASO keywords, icons in every format. We get through review in both stores, and if reviewers send the app back, we work out the reasons and resubmit. In 4 years, 100% approval, including in sensitive categories.

Can we integrate native device features?

Yes, with no limits. React Native and Flutter connect native code (Swift/Kotlin) for any capability: the camera with ARKit, Bluetooth, NFC, Face ID, specialized SDKs. We've integrated 30+ native libraries, and no task has ever forced us to give up cross-platform.

How do we order a mobile app, and where do we start?

A 30-minute call; within 24 hours we send a quote broken down by stage, and in 3–5 days we build a clickable prototype for free, before any contract. An MVP core starts at $9,900 and 6 weeks, with payment in stages and the code in your repository from day one.

When it matters

Situations where we help

If you recognize even one, we can be useful

Native development doubles your budget

Two teams, two codebases, two testing cycles, and the same again for every new feature, forever. Whatever your per-platform budget, 40–50% of it goes into duplicating the same logic.

Competitors are in the stores; your release is six months away

Parallel native development for iOS and Android takes 9–12 months. Every month without an app means lost installs, leads and revenue. The first player in a market takes 70% of organic store traffic.

Android lags behind iOS, and your rating drops

Platforms out of sync breed angry reviews: “it's worked on iPhone for ages, but not for us.” Every star lost in the store rating cuts install conversion by 25–35%. That's money you lose every day.

Let's estimate the budget for your task

Describe your task and we'll come back with a timeline and cost estimate within 1 business day. Want to see the product before the numbers? We'll build a free prototype.

What you get

Features and benefits

Concrete results we deliver for you

Proven on our own product: MarchTracker

React Native and Flutter give you 85–95% code reuse. Our own product, MarchTracker, runs on iOS, Android and the web from one codebase: we sell an approach we use ourselves.

A 4.7+ rating thanks to native UX

60 fps animations, platform gestures, Material You and Apple's HIG. Users can't tell the app from a native one, so there are no complaints about an “alien” interface and no rating losses.

+20–30% retention with personalized push

Segmented push notifications, deep linking from emails and ads, in-app messages. Well-tuned notifications bring users back without extra marketing spend: it's a free retention channel.

Payments in 1–2 taps: Apple Pay, Google Pay

Apple Pay, Google Pay, cards, subscriptions, in-app purchases. Every extra step in the payment flow loses 10–15% of users. We design checkout in 1–2 taps, so that money stays with you.

Real-time geolocation and tracking

Real-time tracking, geofences, routing, map integration. For logistics, delivery and field service, that directly cuts transport costs and raises staff utilization.

Offline mode with auto-sync

Local storage, automatic sync when the connection comes back, conflict resolution. For B2B apps in warehouses, plants and the field, where the internet is unreliable, it's the only way not to lose data.

Process

How we work

A transparent process with clear stages and deliverables

Stage 1

UX research and user flows in 1–2 weeks

We analyze the target audience, competitors and user tasks. You get user flows and an information architecture before the first pixel of design.

Stage 2

A free prototype, then UI in 2–3 weeks

First, a free clickable prototype of the key screens in 5 days, before any contract. Then a full design that follows iOS and Android guidelines, tested with real users: we find mistakes in the mockups, not after development.

Stage 3

Development with a build every week

Development in React Native or Flutter in 2-week sprints. Every week you get a test build on real devices. You see progress in your hands, not on slides.

Stage 4

QA on 20+ devices and store launch

Final QA on real devices, plus ASO metadata, screenshots and descriptions. We get through App Store and Google Play review, including disputed rejections, at no extra charge.

Custom mobile app development: how we reduce the risk

Turnkey app development with us starts with a free clickable prototype: you see the key screens before any contract. Then comes an MVP core from $9,900 in 6–8 weeks. We break down what goes into the quote in “How much does a mobile app cost”, and you can estimate a range for your project with the app cost calculator.

One codebase, three platforms: our product MarchTracker is built on Expo/React Native and runs on iOS, Android and the web from a single codebase.
