Mobile App
Development

Apps people open every day. And don't delete after a week.

Building an app is the easy part. Building an app people love, return to, and recommend — that's the real story. The difference is in the details: performance, UX, battery life, offline sync, notifications that don't annoy. Every small detail can sink an app.

We've been building iOS and Android apps for five years. From an MVP shipped in eight weeks to apps serving hundreds of thousands of users. We've learned where the pitfalls are — and how to avoid them.

// 01 · What we build

What we build

From B2C to B2B, from e-commerce to AI-powered apps. Every app — tailored to its audience.

  • 01

    B2C apps

    For end consumers. Retail, finance, health, leisure, media. Anything a person opens on their phone to get something done.

  • 02

    B2B & internal apps

    Tools for organizations, field management, employee apps. Operational, stable, working.

  • 03

    E-commerce apps

    Native stores. Fast, smooth, one-tap checkout. Higher conversion than mobile web.

  • 04

    SaaS apps

    A mobile companion to an existing product — or a platform that's mobile-first from day one.

  • 05

    AI-powered apps

    Smart chatbots, image and document scanning, personalized recommendations, AI agents. On mobile and on-device.

  • 06

    PWA

    Progressive Web Apps. Sometimes a native app isn't the answer. PWAs deliver an app-like experience — no stores, no download.

// 02 · Approach

Native, Cross-Platform, or PWA — which fits you?

This is the first question we help you answer. There's no single right answer. We don't push technology — we recommend based on the project.

  • 01 · Maximum performance

    Native

    Swift / Kotlin

    + Maximum performance, full access to device features, perfect experience.

    − Two codebases, double the development, double the maintenance.

  • 02 · The fast lane

    Cross-Platform

    React Native / Flutter

    + One codebase, two platforms. 90% of native performance, at half the cost and time.

    − Right for most apps. For extreme performance needs — go native.

  • 03 · No app stores

    PWA

    Progressive Web App

    + A website that behaves like an app. No download, no updates, no store.

    − Great for some products — not all. Limited access to full device capabilities.

// 04 · How we work

How we work

  1. 01STEP 1

    Understand the product

    Who is the user? When will they open the app — coffee in the morning, couch in the evening, on the bus? Every detail shapes the design.

  2. 02STEP 2

    Mobile-first UX

    Mobile isn't a tiny desktop. One hand, small screen, short bursts of attention. We design for the real experience.

  3. 03STEP 3

    Platform-native design

    Material Design for Android, Human Interface Guidelines for iOS. Or a custom design that works beautifully on both. No generic templates.

  4. 04STEP 4

    Iterative development

    Two-week sprints. At the end of every sprint — a live build you can install and try. You don't wait two months to see if it works.

  5. 05STEP 5

    Testing on real devices

    Not just simulators. Real iPhones and Androids, different OS versions, different resolutions. "Works on my machine" doesn't fly on mobile.

  6. 06STEP 6

    Store launch

    We handle the App Store and Google Play submissions. ASO, screenshots, descriptions, responses to rejections. You don't deal with any of it.

  7. 07STEP 7

    Post-launch maintenance

    iOS and Android updates ship constantly. We update, fix, add features. Your app never falls behind.

// 05 · Who it's for

Who this is for

  • 01

    Startups

    Need an app as their primary product. Fast MVP first, scale later.

  • 02

    SaaS companies

    Need a mobile version of an existing product. An app that feels like part of the product — not an afterthought.

  • 03

    Businesses

    Want a customer app — ordering, loyalty, notifications, retention.

  • 04

    Enterprises

    Need an internal app for field workers and operational teams.

// 06 · Why us

Why us

  • 01

    Mobile is a craft

    Not every web developer knows mobile. We work on mobile every day, know every pitfall — and how to step around it.

  • 02

    End-to-end ownership

    From discovery to App Store approval. You don't manage vendors — we manage everything.

  • 03

    Real availability

    A bug on mobile means customers walking away. We respond within an hour — at night, on weekends, always.

  • 04

    Experience

    Hundreds of projects behind us. You get the result — without having to make the mistakes.

// 07 · FAQ

Frequently asked questions

  • 01.How much does it cost to build an app?

    It depends on complexity. A simple MVP — starting at ~$22K. A medium app — $40K-$80K. A complex or AI-powered app — more. We'll give you a precise number after one discovery meeting.

  • 02.How long does it take to build an app?

    MVP — 8 to 12 weeks. A medium app — 4 to 6 months. A complex enterprise project — 6 to 12 months.

  • 03.React Native or native — which is better?

    It depends on the project. Most apps get a great result with React Native — at half the time and half the cost. For extreme performance needs, heavy graphics, or deep device feature usage — go native.

  • 04.Do I need an app, or is a responsive site enough?

    Great question — not every product needs an app. If there's no recurring use, no offline need, and no push notifications — a responsive site or PWA is enough. We'll tell you straight.

  • 05.Who owns the app and the code?

    You do. No "buts." Your code, your store accounts, everything is yours.

  • 06.Do you handle store submissions?

    Yes. App Store and Google Play — we handle everything: ASO, screenshots, descriptions, responses to rejections (there's always a first rejection).

  • 07.What about post-launch maintenance?

    Launch isn't the end — it's the beginning. iOS/Android updates, new features, bug fixes, optimization. We stay with you.

  • 08.Do you build for tablets too?

    Yes. iPad and Android tablets. A proper adapted design — not a stretched phone screen.

  • 09.Do you build the backend too?

    Both. Most apps need a backend — server, database, API. We build the whole stack.

  • 10.Do you integrate AI into apps?

    Yes. Chatbots, image scanning, smart recommendations, AI agents. Both through external APIs (OpenAI, Claude) and on-device models.
