Timelines depend on the number of features, platforms, and integration requirements. We always set realistic delivery dates and work in fast sprints.
Can you help if I only have an idea?
Yes. We offer product discovery & prototyping services. We’ll help you define the core features, design user flows, and build an interactive prototype — perfect for pitching or validating your concept.
Do you sign NDAs?
Absolutely. We respect your privacy and intellectual property. We’re happy to sign an NDA before we start any discussion or share materials.
Who owns the code after development?
You do. Once the project is completed and paid for, you get full ownership of the source code and all deliverables. We can also transfer them directly to your GitHub or cloud repo.
Do you provide post-launch support?
Yes, we offer support packages ranging from basic bug fixes to full-featured maintenance and updates. You can choose a monthly plan or request on-demand support.
What technologies do you use?
We choose tech depending on your needs:
- Frontend: Flutter, React Native, Swift, Kotlin
- Backend/APIs: Node.js, Firebase, Django
- Design: Figma, Adobe XD
- Project tools: Trello, Notion, Slack
Can I update the app after launch?
Yes. Our agile development process makes it easy to scale. You can add new features anytime — either through a one-time scope or a continuous development contract.
Do you work with international clients?
Yes, most of our clients are from Europe, North America, and the Middle East. We work remotely and communicate via email, Slack, or video calls in English.
