Hey Product Hunt! 👋 I'm the maker of STOPRO. As a solo developer, I've shipped multiple apps — and every single time, the store screenshots took longer than I wanted to admit. Hiring a designer felt overkill for a side project. Doing it myself in Figma took hours. And when I wanted to add Japanese localization? Start over. So I built STOPRO. It uses Google's Gemini to generate professional store visuals from your raw screenshots. The key insight: it's not just "AI image generation" — it's a workflow designed around how App Store and Google Play actually work. Upload → Master design → Device expansion → Language expansion → Download ZIP. That's it. Would love your feedback — especially from fellow app developers who've felt this pain. What would make this more useful for your workflow?
