Services

Any software — one team

There is no project type we treat as “not our profile”. If it can be built, APP NS can build it.

Mobile applications

Native iOS and Android apps, plus cross-platform builds when one codebase makes more sense. From the App Store and Google Play release to updates and analytics.

Web applications

Corporate sites, landing pages, online stores, portals, dashboards and complex web platforms that stay fast on every screen size.

Backend & APIs

Server logic, databases, REST and GraphQL APIs, cloud infrastructure and everything that keeps your product reliable under real load.

Custom business software

CRM, ERP and internal systems, booking and delivery tools, admin panels and automation for processes that no ready-made product covers well enough.

Desktop software

Applications for Windows, macOS and Linux — from small utilities to specialised tools that work with local hardware and data.

Integrations & automation

Payments, maps, messengers, ERP and third-party services connected together — plus scripts and pipelines that remove manual routine work.

UI/UX design

Interface design, prototypes and design systems — interfaces people understand without a manual.

QA, support & maintenance

Testing, bug fixing, performance work, security updates and new features after the launch — we do not disappear on release day.

Technology

Tools we work with every day

We pick the stack that fits the task and your budget — not the one that is trending this month.

Process

How a project runs at APP NS

  1. 01

    Talk

    You describe the idea or the problem. We ask the questions that matter and tell you honestly what is realistic.

  2. 02

    Scope & estimate

    A written plan with features, timeline and price. No hidden items appearing halfway through.

  3. 03

    Design & build

    Development in short iterations with working builds you can open and test at every stage.

  4. 04

    Launch & support

    Release to the stores or your servers, then monitoring, updates and new features as you grow.

Why APP NS

A small team, a direct line

You talk to the people who actually write your code. Questions get answered the same day, decisions do not wait for three layers of management.
