Mobile app development

Mobile applications designed for the real context in which they are used.

We develop Android, iOS and cross-platform applications for field teams, B2B services and products that need camera, location, notifications, offline work or fast phone access.

When mobile matters

A mobile app should be justified by context, device capabilities and usage frequency.

We verify whether a responsive web application is sufficient before adding the cost of mobile platforms and stores.

Field

Users work away from a desk

We optimize steps, data and synchronization for variable connectivity and quick use.

Device

Camera, GPS or sensors are required

We use phone capabilities with clear permissions and fallback behavior.

Offline

The workflow must continue without internet

We define local storage, conflicts and synchronization before implementation.

Product

Interaction is frequent and personal

We build onboarding, notifications and states that respect user attention.

Coverage

From mobile workflow and API to publishing and monitoring.

The native or cross-platform choice is explained through requirements, experience and maintenance cost.

  • product analysis and selection of native, cross-platform or web delivery;
  • UX/UI for small screens and one-handed use;
  • authentication, secure storage and permission handling;
  • integration with APIs and existing systems;
  • photographs, location, notifications and offline functions where required;
  • testing on relevant devices and operating-system versions;
  • preparation and publishing in application stores;
  • error monitoring, updates and post-launch support.

Delivery process

A clear technical process with reviewable decisions and deliverables.

Stages are adapted to product maturity, risk and objectives without adding unnecessary complexity.

01

Discovery

We define users, environment, devices, connectivity and capabilities that justify the application.

02

Definition

We design workflows, offline behavior, API contracts and the distribution strategy.

03

Implementation

We build and test in increments, using real devices for priority scenarios.

04

Validation and support

We verify permissions, weak networks, resource use, errors and the publishing process.

Public product

Infracheck: phone-side network diagnostics on Android

The application checks the phone network and can add monitoring data from an optional local appliance.

FAQ

Frequently asked questions

Do you develop for Android and iOS?

Yes. We can use native development or a cross-platform codebase depending on capabilities, performance, devices and maintenance budget.

Can the application work offline?

Yes, when the workflow is explicitly designed for local storage, synchronization and conflicts. Offline is not simply a switch added later.

Do you handle app-store publishing?

We can prepare builds, assets and the publishing process. Accounts and final acceptance belong to the organization and the respective platforms.

Is a mobile app better than a web application?

Not by default. The choice depends on device functions, offline needs, frequency, distribution and the required experience.

Can you connect the app to an existing backend?

Yes, after reviewing APIs, authentication, limits and the way versions and errors are managed.
