Mobile App Development for Android and iOS

App development for the people who use it every day

Mobile app development with us starts with one question: what should the app do for your business? Sometimes it is a client portal on the phone, sometimes a tool for a field team, sometimes a companion to an existing website. Once we understand the job, we choose the screens, the data and the scope of the first version.

We build apps in Flutter. One codebase gives you an Android app and an iOS app that look and behave the same, and every change ships to both platforms at once. That keeps development and maintenance cheaper than running two separate native apps. For you that means one team, one quote and one roadmap.

We write the backend in Laravel with a MySQL database. If you already have a website or an internal system, the app connects to it through an API, so your data stays in one place and nobody has to copy it by hand. If you have no system yet, we build the backend from scratch, with an admin area where your team sees users, orders and messages without calling a developer.

What mobile app development with us includes

The whole path from idea to an app in the store, with the same team from start to finish.

Flutter for Android and iOS

One codebase for both platforms. Fixes and new features reach Android and iOS together, and you pay for one development effort instead of two separate projects.

Laravel backend and API

We build the server, database and API the app relies on. If you already run a website or business software, we connect the app to that data instead of duplicating it.

Push notifications for users

Alerts for new messages, order status or appointments. We ask for permission at the right moment, and users choose which kinds of notifications they want to receive.

Sign-in and data protection

Secure sign-in, encrypted traffic to the server and in-app account deletion, which Google Play and the App Store now require from every app that has user accounts.

Release to app stores

We prepare the listing, screenshots, privacy policy and reviewer details, then submit the app to Google Play and the App Store under your company's developer accounts.

Maintenance after launch

New Android and iOS versions call for regular updates. We monitor errors, update libraries and add features when your business needs them.

Who our app developers work with

An app makes sense when people open it often, not just once.

Companies with repeat clients

When clients order regularly, track status, pay invoices or book appointments, an app saves them calls and emails and saves your team time.

Teams in the field

Technicians, sales reps and couriers who enter data on their phones instead of retyping it into a spreadsheet at the end of the day.

Companies with an existing system

You have a website, portal or internal software and users want access from their phones. The app uses the same data through an API.

New products and startups

A first version with the core features, solid enough for real users, followed by development driven by what those users actually do.

How our app development process works

Timeline and price are set in the quote after scoping, not guessed upfront.

Call and estimate
A short call about who uses the app and what they do in it. After that you get a free estimate of scope, price and timeline, with no obligation.
Specification and screens
We write down the features of the first version and sketch the key screens. Before any code is written you know exactly what you get, and changes are cheap on paper.
Development in phases
We build the app and backend in smaller pieces. After each phase you install a test build on your own phone and give feedback.
Testing and release
We test on Android and iOS devices, prepare the store materials and submit the app for review on Google Play and the App Store.
Support and new versions
After launch we monitor errors and usage, update the app for new system versions and add features in the order of your priorities.

Systems we have built

Apps and portals we wrote ourselves, from the screens down to the database.

IT services

IT Expert client app

A Flutter app for our own clients: plan and subscription, support tickets, chat with the team, invoices, booking and video consultations, notifications and account deletion. It runs on the same Laravel backend as our web portal.

Result One codebase for Android and iOS and one API for web and mobile, so every new feature reaches all platforms at once.

Dental manufacturing

NST Print and Mill Centar

A private portal for dental labs: ordering at contracted prices, scan uploads up to 500 MB, pro forma invoices, monthly billing with a credit limit, automatic payment reminders and SEF e-invoicing.

Result The whole path from an uploaded scan to the pro forma invoice happens inside the portal, without email or manual retyping.

All portfolio projects

Mobile app development cost, technology and choosing app developers in Serbia

There is no fixed price for mobile app development because apps differ a lot. The cost depends mostly on the number of screens, user accounts, payments, offline use, push notifications, integration with existing systems and how much work the backend does. That is why we talk first and then send an estimate with a clear scope for the first version. You get the exact amount in the quote, and later features are estimated separately.

For most business apps we choose Flutter. Android development and iOS development then become one project instead of two. You get the same look and behaviour on both platforms, one team and one place for fixes. The backend runs on Laravel and MySQL, and the same backend can also serve your website or portal, so web and mobile share the same data.

Before you contact us, it helps to write down who will use the app, the three to five things it must do in the first version, and whether it has to connect to a system you already run. You do not need a technical specification. We write it together in the first phase and it becomes part of the quote.

When you choose a mobile app development company, ask who writes the code, who builds the backend and who maintains the app after launch. With us you work directly with senior developers, with no sales layer in between. The app is published under your company's accounts, so it stays yours even if you change teams later. Ask to see systems they built themselves, not just screen designs.

We are based in Belgrade, Serbia, and work remotely with clients across Serbia and abroad, using video calls and test builds you install on your own phone. You do not need in-person meetings, and you see progress after every phase. Whether you are in Belgrade, Novi Sad, Nis or Kragujevac, the process is the same. The first consultation is free and without obligation, and we reply within 24h on working days.

Mobile app development FAQ

How much does it cost to develop a mobile app?

It depends on scope, so we do not sell apps as fixed packages. Screens, user accounts, payments, push notifications and integrations have the biggest impact. After a short call we send a free estimate with the scope of the first version, the price and the timeline, with no obligation.

How long does mobile app development take?

We set the timeline in the quote after scoping, because it depends on the features in the first version. Work is split into phases and you get a test build after each one, so you see progress from the start rather than only at the end.

Do you build apps for both Android and iOS?

Yes, both from one codebase. We use Flutter, so the Android and iOS apps look and work the same. One change reaches both platforms, which keeps development and maintenance cheaper than two separate native apps. The app is then released in both stores.

What is Flutter and why do you use it?

Flutter is Google's toolkit for building apps that run on Android and iOS from a single codebase. We use it because it produces fast apps with the same interface on both platforms, and it gives you one development effort, one team and simpler maintenance.

Do you also build the backend?

Yes. We build the server, database and API in Laravel with MySQL. If you already have a website or business software, we connect the app to your existing data through an API instead of creating a separate database. That way web and mobile show the same data.

Do you publish the app on Google Play and the App Store?

Yes. We prepare everything for review: the listing, screenshots, privacy policy, account deletion and reviewer access. The app is published under your company's developer accounts in both stores, so you keep ownership. If reviewers ask for changes, we fix them and resubmit.

What if I already have a website or internal system?

That is a good starting point. The app uses the same data through an API, so users see the same information on web and mobile. If your system has no API yet, we assess whether it is simpler to add one or to build a new backend.

Who maintains the app after launch?

We do, if you want us to. New Android and iOS versions require regular updates and the stores change their rules from time to time. We monitor errors, update libraries and add features, and the maintenance scope is agreed separately based on how often the app changes.
