Hey everyone! 👋 With the rise of vibe coding tools, more people than ever are publishing their first app to the App Store. But here's the thing — design guideline violations are the 3rd most common reason for app rejection. Creating screenshots in the right sizes for every device? It's surprisingly painful, especially if you're not a designer. So I built appkit — a free tool that makes it dead simple: Upload your app screenshots Pick a background, add captions & device mockups (iPhone, Galaxy, iPad) Download all 8 sizes as a ZIP — for both App Store & Google Play It costs me almost nothing to run, so it's completely free. No login, no watermark, 100% browser-based — your images never leave your device. Would love your feedback — what would make this more useful for you?
