Marketing Collateral Design for Mobile Launch

I’m gearing up to launch a new mobile app on both iOS and Android, and I need a creative partner to produce all the marketing materials that will give it a polished, professional look. The core of the project is graphic design—everything from eye-catching social media visuals to sleek promotional assets that speak clearly to potential users on both platforms.

Here’s what I have in mind:
• A consistent visual theme that can be adapted across social posts, digital ads, and in-app banners
• App-store–ready imagery (screenshots, feature graphics) tailored separately for the Apple App Store and Google Play
• Optional print pieces such as postcards or posters if you feel they would strengthen the campaign

I’ll supply the brand guidelines, sample copy, and any existing graphics we want to keep. What I’m looking for from you is:
• Concept development and at least two initial design directions
• Revisions until we lock in the final look
• Delivery of layered source files (Adobe Illustrator or Photoshop) plus web-ready exports

If you have experience designing for both iOS and Android launches—and a portfolio that showcases marketing materials in action—I’d love to see it. Let’s create visuals that give this app the standout introduction it deserves.
