Mobile App Image Asset Design

FixWhistle, our soon-to-launch home-services app, now needs a complete, visually consistent image library. The job covers every graphic that appears in the catalog hierarchy:

• Main category banners
• Sub-category tiles
• Individual service thumbnails

Each layer has its own custom size. I will supply the exact pixel dimensions for all three asset types before work begins, so you can set up the right art-boards straight away.

Visual direction
The look must feel clean, minimal and premium while still looking realistic enough for users to recognise the service at a glance. Think crisp lighting, balanced colour, and zero visual clutter. Consistency across the full set is critical.

Deliverables
• Final PNGs optimized for mobile (main categories, sub-categories, individual services)
• Source files organised and labelled (AI, PSD or Figma, whichever you prefer)
• A simple style reference sheet summarising colours, shadows, and corner radius values so the development team can extend the system later

Acceptance criteria
• Exact custom pixel sizes met for every asset
• Cohesive style when images are viewed side by side in the prototype
• No noticeable loss of quality on high-density screens (tested on 3×)

Please include a link to your portfolio that highlights realistic, app-ready graphics, note any relevant mobile UI projects you have handled, and give an estimated turnaround time for the full set. Strong execution on this project can open the door to ongoing design work as FixWhistle expands.
