Tool

Generate Image

App Store screenshots are one of the biggest drivers of download conversions. The background design behind your screenshots sets the tone and communicates your app's quality before users read a single word. Generic gradients don't cut it anymore — you need distinctive, professional backgrounds.

ToolRouter's text_to_image skill generates unique backgrounds tailored to your app's brand and category. Use upscale_image to ensure every asset is crisp at Apple's and Google's required resolutions. From subtle textures to bold graphic compositions, AI creates backgrounds that make your screenshots pop.

This is critical for indie developers competing against well-funded apps, app marketing teams running ASO experiments, and agencies managing App Store listings for multiple clients who need fresh creative fast.
