I will fix and polish iphone and android app UI
Hector Gonzalez
About this gig
I will fix and polish your iPhone or Android app UI using SwiftUI or Flutter.
If your app works but looks basic, messy, misaligned or unfinished, I can improve the screens directly in code and deliver clean source files.
This is not just UI feedback or a design mockup. I work inside your app project and improve the actual mobile UI.
I can help with:
- SwiftUI or Flutter UI fixes
- Layout, overflow, spacing and alignment issues
- Better typography, buttons, cards, forms, lists and tabs
- Responsive UI for different phone sizes
- Onboarding, empty states, quiz screens, dashboards and profile screens
- Light mode or dark mode
- Simple animations and micro-interactions
- Mascot or character-based UI moments
- Source code delivery
This is great for MVPs, startups, AI apps, education apps, productivity tools, fitness apps, kids apps, quiz apps and any app that needs to feel more premium before launch.
Please note: this gig focuses on front-end mobile UI polish. Backend, payments, complex APIs and App Store submission are not included unless discussed first.

I build native iOS apps with Swift and SwiftUI.
I do more than write code. I care about the product, the user flow, and the small details that make an app feel polished. When it fits your idea, I can also help with onboarding, brand personality, mascot-style assets, streaks, gamification, and UX improvements to make the app more engaging.
I treat every app like it matters. You can expect clear communication, clean code, thoughtful design, and a user experience built with purpose.
