Frequently asked questions

How much does mobile app development cost?

The cost of development services depends on the complexity of functionality, selected platforms, and integrations. After a detailed discussion of requirements, we provide a transparent and well-grounded estimate so you can plan your budget.

Who owns the code and rights to the mobile app after development?

You receive full ownership of the code, design, and intellectual property of the product. We guarantee that all development results become your property. This gives you full control over the product and the ability to further develop or scale it without limitations.

Do you ensure data security and GDPR/CCPA compliance?

Yes, we follow a compliance-first approach and adhere to data protection and privacy standards such as GDPR, CCPA, and other relevant regulations, ensuring a secure and reliable product.

Can the app be integrated with my CRM, payments, or third-party APIs?

Yes, our mobile software solutions easily integrate with CRM, ERP, payment systems, and other third-party services, automating business processes and increasing product efficiency.

Which technologies are better to use, native or cross-platform?

The choice of technology depends on your goals, timelines, and budget. As your technology provider, we analyze all options and recommend the optimal approach for fast time-to-market without compromising quality and performance.

What do I need to prepare before starting development?

A business idea, main product development goals, key functionality, and preferred platforms. A clear vision helps us quickly build an MVP and minimize development risks. This ensures an efficient project start and contributes to achieving your business results.

How long does mobile app development take?

The timeline depends on the features, platforms, integrations, and testing requirements. A focused MVP can be delivered in less than 60 days when the agreed scope allows. Larger products require more time, with milestones defined before development starts.

Which is better for my app, native or cross-platform development?

Native development suits deep platform integration and demanding performance requirements. Cross-platform development can reduce duplicated work when iOS and Android need similar functionality. See our native vs cross-platform comparison for the main differences.

Do you support the app after launch?

Yes, we provide post-launch maintenance, bug fixes, and compatibility updates for new operating system versions. We agree on the support scope and response times based on your app’s needs. New features can be planned separately.

Can you take over an existing mobile app?

Yes. We first review the codebase, architecture, dependencies, and available documentation. For a legacy app, we assess what can be maintained and what needs to be refactored, then agree on a plan for support or further development.
