FREQUENTLY ASKED QUESTIONS

Everything you need to know before starting your project.

The cost depends on scope, integrations and target platforms (iOS, Android, or both). Basic mobile apps start at around €6,000–12,000, larger projects (with backend, integrations, AI) range from €20,000–60,000+. After our first call and requirements analysis, we provide a concrete quote.
A standard mobile app deployment (from UI design to app store release) takes 3–6 months. MVPs can be completed in 6–10 weeks. Larger projects with AI or complex backend take 6+ months. After our first call we provide a realistic timeline.
After deployment we offer maintenance and continued development. This means: updates for changing OS requirements (new iOS, Android versions), bug fixes, new features on request, monitoring. Collaboration can be a monthly retainer or flexible hours.
Yes. We build integrations with LLM models (OpenAI, Anthropic) and custom machine learning models. Our latest project is Vizoo — a mobile app with AI analytics for zoos. We also advise clients how to use AI in existing apps — from chatbots to data analysis.
We work in iterative cycles — every 2–3 weeks we show progress and collect feedback. Changes are part of the process. Larger scope changes are discussed separately, we evaluate impact on timeline and cost, and decide together.
Yes, NDAs are standard before our first detailed conversation. We also work in compliance with GDPR and maintain client information confidentiality. We have experience working with public institutions and financial companies where confidentiality standards are high.
It depends on your goals. App for one platform (e.g. iOS only) — native Swift. For both platforms simultaneously and with budget — Flutter (one codebase, two platforms). For apps requiring maximum performance — native iOS + Android separately. We advise during the first call after understanding your project.
The first call is a free consultation (30–60 minutes, online or in our office). We ask about project goals, users, budget, timeline. After the call we send a summary with our assessment and proposed next steps. No commitments.
