Service 06 / 07 — Mobile Development

In their pocket, on their mind.

A mobile app puts your business one tap from your customer — past the browser, past the inbox, straight onto the home screen. We design and build iOS and Android apps with React Native: one codebase, native feel, often close to half the cost of building everything twice.

And we carry it all the way: strategy, design, development, the App Store review gauntlet, and the releases that come after. Shipping to the stores is where most app projects quietly die. Ours don't.

Sound familiar?

The idea is stuck between a napkin and a quote.

You know what the app should do — you've described it a dozen times. But the quotes you've collected range from suspiciously cheap to face-meltingly expensive, each with a different technology opinion, and none explaining what you'd actually get in month one versus month six.

Or you have an app already: built by a freelancer who's moved on, crashing on the newest OS version, with reviews mentioning bugs faster than you can fix them. Every update feels like surgery on a patient nobody has the charts for.

The pattern behind both stories is the same — apps fail on scope and stewardship, not on ideas. The fix is a first version cut down to what proves the product, built on a stack one team can maintain, with someone accountable after launch day.

What we build

The work, specifically.

Cross-platform apps

One React Native codebase shipping to both stores — native performance and feel, one team to maintain it, one budget instead of two.

Product design

Flows, wireframes and polished UI tested on real devices — because an app is judged with thumbs, not mouse cursors.

Backend & APIs

The server side your app stands on: authentication, data, payments, push notifications — engineered as carefully as the pixels.

Store publishing

Developer accounts, certificates, listings, screenshots, review communication — and the rejections handled when they happen. They happen.

Analytics & crash reporting

Knowing what users do and what breaks from the first release — so the roadmap is written by behavior, not by the loudest opinion.

Ongoing releases

OS updates, new features and maintenance on a predictable monthly rhythm — apps are gardens, not statues.

What working with us looks like

Your project, phase by phase.

01

Weeks 1–2

Cut the scope until it's launchable

A product workshop with one uncomfortable goal: remove features. The first version keeps only what proves the product to real users — everything else goes on a roadmap, not in the build. This is where we save you the most money, and it's why our quotes come with fewer zeros than you feared.

You walk away with

A scoped v1 spec with a fixed quote and honest timeline.

02

Weeks 2–4

A prototype on your phone

Design becomes a tappable prototype running on your own device — not a slideshow. You'll catch what feels wrong in thirty seconds of thumb-time that no meeting would have caught. We validate with a handful of real target users before a line of production code.

You walk away with

A validated design you've held in your hand.

03

Weeks 4–12

Build in two-week heartbeats

Development runs in two-week sprints, and every sprint ends on your phone via TestFlight and Android internal tracks. The app grows in your pocket, not in our repository. Backend, payments and notifications are built alongside — no 'we'll integrate it later' cliffs.

You walk away with

A test build on your device every other Friday.

04

Weeks 12–14

Through the store gauntlet

We prepare listings, screenshots and privacy declarations, submit to both stores, and handle review feedback — including the arbitrary rejection Apple likes to send at least once. You get launch monitoring from the first hour: crashes, reviews, funnels.

You walk away with

Approved apps live in both stores, monitored from hour one.

05

Ongoing

Version 1.1 is where apps are won

Real usage data rewrites every roadmap — the feature nobody asked for gets used daily, the flagship one gets ignored. Monthly releases respond to what users do, OS updates get absorbed before they break anything, and the app compounds instead of decaying.

You walk away with

An app that gets better every month, on a predictable budget.

Tools, chosen on purpose

The stack, with reasons.

Technology choices are business decisions wearing technical clothes. Here's what we reach for on this kind of work — and why.

  • React Native + Expo

    One codebase, both stores, over-the-air updates for fixes that can't wait for review — the pragmatic default for 90% of business apps.

  • TypeScript

    Mobile bugs ship to pockets and wait for store review to fix — we'd rather catch them at compile time.

  • Node.js + PostgreSQL

    A boring, proven backend your app can trust — and any future team can maintain without archaeology.

  • Firebase

    Push notifications, crash reporting and analytics from day one — the operational senses an app needs to improve.

  • RevenueCat

    If you monetize with subscriptions, this is the sane way — receipts, trials and renewals across both stores without hand-rolling the hard parts.

At the end

What you actually keep.

One codebase, both stores

iOS and Android from a single React Native codebase — every future feature costs one build, not two.

Store presence, handled

Accounts, listings and review history under your ownership, with the submission scars carried by us.

Eyes on everything

Crash reporting and analytics wired from release one — you'll know what breaks and what users love.

A roadmap with evidence

A v1.1 plan based on real usage data — the cheapest product research you'll ever get.

Proof — Federalna.ba

We built the official app for a national broadcaster — one React Native codebase for iOS and Android, delivering live news, video and the TV schedule to viewers' phones.

Fair questions

Asked, answered.

Anything else on your mind? Ask directly — a real person answers within one business day.

For roughly nine in ten business apps, React Native is the right answer: one codebase, both stores, materially lower cost, and performance users can't tell from native. The exceptions are heavy 3D, demanding hardware access, or platform-first experiences — if your project is in that tenth, we'll say so and point you to the right specialists.

A focused first version is quoted fixed after the scoping workshop — and the workshop's whole job is shrinking that number by removing features that don't prove the product. Complexity drivers are the usual suspects: payments, real-time features, custom backends. You'll see the price before we start and it won't move after.

A lean first version typically takes 10–16 weeks from kickoff to store approval. The biggest variable is scope, which is exactly why we cut it first. Add a week or two of buffer for store review — Apple's timeline is the one thing we can't fix with engineering.

Completely — accounts, certificates, listings, privacy declarations, review communication, and the occasional rejection that reads like it was written by a random number generator. We've been through the gauntlet enough times to carry apps to approval without drama.

The stores don't stand still — OS updates, new devices, API deprecations. Most clients keep us on a monthly release rhythm: maintenance plus a steady drip of improvements driven by usage data. An unmaintained app doesn't stay still; it slowly breaks.

Yes, after a code audit — we need to know what we're adopting before we promise anything. You get an honest report of the codebase's state and a stabilization plan. Sometimes the verdict is 'solid, let's build'; occasionally it's 'a rebuild costs less than this rescue'. Either way you'll know before spending.
