Mobile apps your clients actually use
We build mobile apps for iOS and Android from a single codebase with React Native. One team, one budget, two platforms. An app that brings clients back, makes buying or booking effortless, and keeps your brand on the screen where your clients spend most of their time.
When you need a mobile app
Your clients live on their phones
Most people now book, buy, and talk to businesses from their phone. An app on the home screen is one tap away from the next purchase, not a Google search where your competitors are waiting.
You want iOS and Android, not double the cost
The traditional route means two separate apps, two teams, and twice the budget. With React Native we write one codebase that runs on both platforms, so you get both apps faster and for less, without compromising the experience.
Clients forget you after the first purchase
Push notifications, reminders, and personalized offers bring back people who have already bought from you. The cheapest client is the one you already have, and an app is the most direct line to them.
Your team works in the field
Technicians, drivers, sales reps, on-site managers. An internal app puts jobs, reports, and data in their pocket, and keeps working when the signal is weak.
You already have a web app or system
If you already run a web app, CRM, or online store, the mobile app connects to the same backend. Your data stays the same everywhere, and you do not rebuild anything from scratch.
You want a product people pay for
If the app is the product itself, a booking platform, subscription, or marketplace, we build it from idea to launch on the App Store and Google Play, ready to grow.
What we deliver
01
Feature and user-flow planning
Before any code, we define what the app does, for whom, and in what order. The first version includes what creates value, not everything that is possible.
02
Screen design and clickable prototype
We design every screen to iOS and Android conventions and give you a prototype you can try on your own phone before development starts.
03
One app for iOS and Android
We build with React Native, the technology behind apps from companies like Meta, Shopify, and Microsoft. One codebase, two platforms, fast and native-feeling on both.
04
Push notifications, payments, and integrations
Notifications, user login, online payments, maps, camera, connections to your existing systems. Everything an app needs to be useful, not just pretty.
05
App Store and Google Play launch
We prepare everything for launch, descriptions, screenshots, and account setup, and guide the app through Apple and Google review until it is live for download.
06
Support and new versions
After launch we track errors and user behavior, update the app for new iOS and Android versions, and add features as your business grows.
How We Build Your App
Discovery and plan
We learn your business and users, define the first-version features, and give you a fixed price and timeline.
Design and prototype
We design the screens and build a prototype you test on your phone. Development starts only once you approve it.
Development and testing
We build for iOS and Android at the same time and send you test builds during development, so you see progress on your own phone.
Launch and growth
We publish the app on the App Store and Google Play, track how people use it, and plan the next versions together.

Frequently asked questions
Everything you need to know about our services.
What is React Native and why do you use it?
React Native is a technology for building mobile apps where one codebase runs on both iOS and Android. For you that means shorter development, lower cost, and easier maintenance, because every change is made once, not twice. The apps behave like real native apps, with access to the camera, notifications, location, and other phone features.
Do I need an app, or is a good website enough?
Honestly, sometimes a website is enough. An app makes sense when clients come back often, to book, order, track a status, or collect loyalty rewards, or when your team needs a tool in the field. If clients contact you once a year, you are better off investing in your website and SEO. In the consultation we tell you openly which option is smarter for your case.
How long does it take to build a mobile app?
A first version with the core features usually takes 8–14 weeks, including design, development, testing, and launch. More complex apps with payments, multiple user types, and integrations take longer. You get an exact timeline after discovery, before you commit.
Who publishes the app on the App Store and Google Play?
We do. We prepare the descriptions, screenshots, and settings, and guide the app through Apple and Google review. The app is published on your own developer account, so it is fully yours.
Can the app use data from my existing system?
Yes. We connect the app to your existing website, online store, CRM, or web app through an API, so your data is the same everywhere. If no such system exists, we build a backend that serves the app and, if needed, a web version too.
Have an idea for an app?
Whether you have a detailed spec or just an idea on paper, we will help you turn it into an app people use. Tell us what you want to achieve, and we will tell you what is possible, how long it takes, and what it costs.
