UI Design & Prototyping FAQ

Specific questions about our interface design and prototyping service

What's the difference between wireframes and prototypes?
Wireframes are low-fidelity structural blueprints showing layout and functionality without visual design. Prototypes are interactive versions that simulate the actual user experience with clickable elements, transitions, and realistic content. We provide both as part of our iterative design process.
How many revision rounds are included?
Our standard packages include 2-3 rounds of revisions depending on the service level. Each round allows for comprehensive feedback and adjustments. Additional revisions can be added at €150/hour if needed, though most projects are completed within the included revisions.
Can you work with our existing development team?
Absolutely! We excel at collaborating with development teams. We provide detailed specifications, annotated designs, and code-ready assets. We can also conduct handoff sessions and remain available during development for clarifications and adjustments.
What devices and browsers do you design for?
We design for all major devices and browsers including Chrome, Firefox, Safari, and Edge. Our responsive designs work on desktop (1920px+), tablet (768px-1024px), and mobile (320px-767px) with specific attention to iOS and Android native behaviors.
How do you ensure the design will work technically?
We collaborate closely with your technical team from the start to understand constraints and possibilities. Our designs follow web standards and include detailed specifications for developers. We also conduct feasibility reviews at key milestones to ensure everything is technically viable.
Do you provide design files in different formats?
Yes, we deliver native Figma files plus exported assets in PNG, SVG, and PDF formats. We also provide CSS specifications, font files, and any other formats your development team requires. All files are organized and properly labeled for easy implementation.
How detailed are your interactive prototypes?
Our prototypes include realistic interactions, transitions, micro-animations, and state changes. They're detailed enough for user testing and stakeholder demonstrations. For complex applications, we create multiple prototype levels from basic click-through to high-fidelity interactive demos.
What happens if we need changes after launch?
All packages include 30 days of post-launch support for bug fixes and minor adjustments. For ongoing changes and optimization, we offer flexible maintenance packages or hourly consulting. We're committed to ensuring your interface continues performing optimally.
