IGTCODE Services Serbia

Mobile app development for iOS and Android

IGTCODE is a software development company in Serbia building Android and iOS apps for businesses, organisations and startups locally and internationally. We connect the mobile experience with backend systems, data and administration that support the way you work.

Let's discuss your project Explore the service

An app for a specific task.

We develop apps for membership, bookings, sales, transport and employee workflows. We start with the user: what they need to do, which data they can see and how the app makes that journey shorter.

For businesses

Customer portals, service ordering and tools for field staff, connected to the business system.

For organisations

Member accounts, events, registrations and communication, with separate access for members and administrators.

For startups

An MVP focused on the most important user journey, to test the idea before expanding development.

iOS and Android development

Flutter is one of our main mobile technologies. It lets us develop much of an app for both platforms together, while checking permissions, device behaviour and platform-specific integrations separately on iOS and Android.

Backend systems and admin panels

An app is part of a wider system. We build backend business logic, APIs and admin panels for managing content, users, orders or membership. We define the scope of administration with the team that will use it.

Features that connect users and business.

We choose features around real needs. Each integration also covers what happens without an internet connection, when a service does not respond or when the user lacks the necessary permission.

Push notifications

Updates about events, requests and status changes, with clear sending rules and control over user permissions.

API integrations

Connections to existing software and external services, after checking API availability and terms of use.

Authentication and accounts

Registration, sign-in, account recovery and user roles. Access checks also run on the backend.

Payments

An appropriate payment provider or in-app purchases, based on the product, market and app store requirements.

Maps and location

Location displays, map-based service search and routes. Location access is requested when an agreed feature needs it.

App Store and Google Play deployment

We prepare production builds, testing and publishing materials. We agree developer account ownership, privacy information and required access with the client. App stores review submissions independently, so approval times cannot be guaranteed.

Technologies and tools

We choose technology around the requirements and existing system. The specific stack and each service's role are agreed during planning.

Flutter
Dart
React
REST API
Cloud Messaging
PostgreSQL
MySQL

How does development work?

Discovery and scope
Define users, the main journey and first-release priorities.
Design and prototype
Check screens and navigation before developing the complete system.
Development and testing
Build the app and backend in stages, testing on real devices.
Publishing and maintenance
Prepare store releases and agree support and further development.

Questions before we start.

How much does a mobile app cost?

The price depends on user journeys, integrations, backend systems and administration. After discussing the first release, we prepare an estimate with a clear scope. There is no single price for every app.

How long does app development take?

Timing depends on complexity, content readiness and external services. A single-journey MVP and a platform with several user roles need different plans. We agree milestones and allow separately for store reviews.

Do you build both Android and iOS apps?

Yes. We develop for both platforms. Where Flutter fits the requirements, we share a codebase and test each platform separately.

Can the app include an admin panel?

Yes. We design it around the data and tasks your team needs to manage, with appropriate user roles.

Do you develop the backend?

Yes. We build backends, databases and APIs. We can also connect to an existing backend where its architecture and access arrangements allow it.

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

We support preparation and submission using the client's required accounts and materials. Final approval is the app store's decision.

Are there monthly costs?

Hosting, databases, messaging, maps, AI services and maintenance may incur ongoing costs. Developer account fees depend on the store. We separate these expenses from development costs.

Is Flutter a good choice for a business app?

Often, especially when both Android and iOS are needed. We first check device-specific requirements, integration availability and expected performance.
