What kinds of apps we build

What the delivery includes

Native and cross-platform

Android and iOS from a single codebase (React Native / Flutter), or native when performance calls for it.

UX/UI design

Screen designs and a prototype, so the app is intuitive and looks professional.

Integrations and APIs

Connections to your systems, e-commerce store, CRM, payment gateways and notifications.

Release and support

Publishing to the App Store and Google Play, updates and long-term maintenance.

Pricing and budget

We can tailor a mobile app to a range of budgets — from a simple first version (MVP) to a full-scale solution. Just enter an indicative budget in the contact form and we will propose a scope that gets the most out of it.

Frequently asked questions

Do you develop mobile apps for both Android and iOS?

Yes. Depending on the brief and budget, we choose a native approach or a cross-platform solution (React Native / Flutter), so a single codebase covers both Android and iOS.

How much does custom mobile app development cost?

The price depends on the feature scope, integrations and design. After a short consultation and your indicative budget, we send a transparent quote and a stage-by-stage plan.

Will you help with publishing to the App Store and Google Play?

Yes — we handle the build, code signing, store guideline compliance and the release itself. After launch, we provide updates and technical support.
