FAQ
Answers to common questions
How much does it cost to build a mobile app?
It depends on features, number of screens, integrations and platforms. After a free consultation we prepare a detailed fixed-price quote or propose a partnership model. We often start with an MVP – the core features – so you can validate the idea with minimal investment.
How long does development take?
A first working version (MVP) is usually ready in 6–12 weeks. Larger systems are built in stages, and you get a demo build to test every week.
Can the app work with my existing database or system?
Yes. We connect the app to your ERP, CRM, inventory software, online store or directly to the database (MySQL, PostgreSQL, MS SQL, Oracle, etc.) via a secure API layer – without disrupting your current systems.
I don't have a database. Can you build one?
Yes. We design and build a custom cloud database and backend with an admin panel where you manage content, users and orders yourself.
Do you also build a website?
Yes. We build an SEO-optimised marketing website, a web version of the app or an admin panel – all on the same database.
What does partnership mean?
For the right projects we can work for a lower upfront price in exchange for a share of revenue or equity. The risk is shared, and we're as motivated as you are for the product to succeed.
Who owns the code and the app?
On a standard project the code, design and App Store / Google Play accounts are fully yours after the final payment. We're happy to sign an NDA.
Do you maintain the app after launch?
Yes. We offer monthly maintenance – updates for new iOS and Android versions, crash monitoring, quick fixes and new features.
Have an app idea? Let's make it real.
The first consultation is free. You'll get an honest assessment, a plan and an estimated timeline – no obligation.
