How much does custom app development cost?
It depends on scope, platforms and integrations. After a short discovery call we provide a clear, itemised estimate — and we often recommend starting with a focused MVP to reach the market sooner.
Do you build both web and mobile apps?
Yes. We build responsive web applications and cross-platform iOS and Android apps, often sharing code and APIs between them to reduce cost.
Can you take over an existing app?
Yes. We start with a code and architecture review, then stabilise, modernise and extend the application in stages.
Can you add AI features to our existing product?
Yes. Assistants, smart search, document processing and recommendations can usually be integrated into an existing product through APIs, without a full rebuild.
