FAQ
What do you need before starting my app design?
Please share your app idea, target users, required screens/features, branding, content, references, and any wireframes or sketches you already have.
Do you develop or code the mobile app?
No. This gig focuses on UI/UX design and interactive Figma prototyping. You receive an organized, developer-ready Figma file for implementation. And if that's what you need just text with DEVELOPER
Can you design for both iOS and Android?
Yes. I design interfaces for both iOS and Android while considering the appropriate platform patterns, usability, navigation, and screen behavior.
Will my Figma prototype work like the actual app?
The prototype will simulate important navigation, interactions, buttons, and screen flows so you can demonstrate and test the experience before development.
Can you redesign my existing mobile app?
Yes. Send your existing screens or Figma file and explain what feels outdated or difficult to use. I can restructure the UX and refresh the visual interface.
Will the Figma file be ready for my developer?
Yes. Files are organized with named layers, reusable components, consistent styles, Auto Layout where appropriate, assets, and clear screen structure.
What counts as one screen?
A unique app page such as Login, Home, Profile, Checkout, or Dashboard counts as one screen. Complex states, popups, or extra variations may count separately.
