You're a developer, not a designer.

Your app is great. Your screenshots? They're costing you downloads.

Hours wasted in Figma

You spend more time arranging screenshots than building your app. Alignment guides, device frames, exporting at 3x...

Screenshots that don't convert

You know your app is great, but your screenshots look like they were made at 2 AM before submission. Because they were.

No time for localization

You know localized screenshots boost downloads. But translating captions for 5+ languages? You'll get to it "next release."
