Frequently asked questions
Native or cross-platform?
We recommend based on your features, budget and timeline. Many products launch faster and cheaper with Flutter or React Native.
Which technologies do you work with?
We are tool-agnostic and work across modern stacks — React, Next.js, Flutter, React Native, Node.js, Python, Laravel, PostgreSQL, MongoDB and more — choosing what fits your product and team.
Can you take over an existing product?
Yes. We start with a code and architecture review, stabilise what is critical, and then continue development and support.
