MOBILE DEVELOPMENT // iOS + ANDROID

Mobile app development for iOS and Android

We build mobile MVPs and scalable apps with a clear plan, regular demos, and complete source-code handover.

Applications for businesses and startups

Customer services, marketplaces, subscription products, internal tools, and applications for delivery, education, health, and other industries.

What mobile development includes

Product discovery, UX/UI, iOS and Android, backend and APIs, administration tools, payments, authentication, push notifications, and analytics.

Testing and store release

We test key user flows and devices and prepare builds, materials, and settings for App Store and Google Play release.

Outcome and support

The client receives a production application, source code, infrastructure, documentation, access credentials, and post-launch support.

Mobile application estimate

Timeline and budget depend on platforms, roles, screens, integrations, offline behavior, payments, and backend requirements. The first release focuses on the workflow that validates the business hypothesis fastest.

Native or cross-platform development

We choose Swift, Kotlin, or a cross-platform stack based on performance, device capabilities, timeline, and product roadmap rather than attachment to one technology.

Preparing the product for growth

We add event analytics, error monitoring, test environments, and a controlled release process so the next version is guided by data and does not require rewriting the application.

Mobile application development questions

What is included in mobile application development?

UX/UI, iOS and Android applications, backend, administration panel, analytics, push notifications, and store publication support.

Do I need a finished technical specification?

No. A description of the business, users, and key objective is enough. The team will define the user flows and first-version scope.

Who owns the source code?

After payment, the source code, repository, infrastructure, publishing accounts, and documentation are transferred to the client.

Commercial terms

Preliminary first-release orientation

Timeline: from two months. Starting range: $3k–5k / €3k–5k. Advance payment: 20% after prototype approval.

These are preliminary orientations, not an offer or final estimate. Final scope, timeline, and price are confirmed after the prototype and integration review.

Questions before the start

How much does the first application release cost?

We confirm the estimate after discovery and prototype work clarifies platforms, roles, integrations, and the first-release boundary. The proposal is prepared for the actual scope instead of using an invented fixed package.

How long does development take?

A first production release usually takes from two months. The exact timeline depends on platforms, integrations, offline workflows, and first-release scope.

Do we need a finished technical specification?

No. Tell us about the business, users, and goal in plain language. We will define the flows, requirements, prototype, and acceptance criteria.

Native or cross-platform development?

We choose Swift, Kotlin, or a cross-platform stack based on performance, device capabilities, timeline, and the product roadmap.

How does payment work?

We first approve the prototype and scope. The client then pays 20% upfront. The balance is paid after completion and before handover.

Who owns the source code and accounts?

After payment, the source code, repository, infrastructure, and publishing accounts are transferred to the client. Ongoing support and development are agreed separately.

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

Yes. We prepare production builds, store listings, and technical settings and support the review process. Developer accounts belong to the client, while final approval remains with Apple and Google.
