App Logo & Screenshot Design

I’m preparing to publish a new mobile application and I need a full set of store-ready graphics. The visual tone must feel professional and corporate, yet I’m completely open to your color ideas—if you can justify the palette, I’m happy to explore it.

Here’s what I need you to hand over:

• App logo
– iOS: 1024 × 1024 px, PNG, no transparency, square corners
– Android: 512 × 512 px, PNG (32-bit with alpha), main content kept inside the central 66 %
– Original, editable source file (Adobe Illustrator, Figma or similar)

• Phone screenshots (8)
– PNG or JPEG, 9:16 aspect ratio
– 320 px – 3840 px on the longest side, ≤ 8 MB each

• 7-inch tablet screenshots (5)
– PNG or JPEG, 16:9 or 9:16
– 320 px – 3840 px on the longest side, ≤ 8 MB each

Acceptance criteria
1. Every file passes App Store and Play Console validation without resizing or reformatting.
2. Visual style is consistent across logo, phone, and tablet assets.
3. Source file layers are clearly named so future edits are straightforward.

If you’ve produced store assets before, please share a link or attachment from your portfolio so I can see how you handle layout, typography, and callouts.
