Browser-only App Store & Google Play screenshot studio and icon packager — no upload, no account.
CLIENT OR PRODUCT
Independent web product (Launch Studio).
MY ROLE
Independent product builder — web tool, end to end
THE PROBLEM
Developers waste hours resizing screenshots, writing store copy layouts, and packing Xcode/Android icon sets for App Store Connect and Google Play.
CONSTRAINTS
- •All image work must stay in the browser (privacy)
- •Exact Apple and Google pixel specs
- •iPhone, iPad, Android phone/tablet frames and templates
- •Xcode AppIcon.appiconset + Android mipmap / adaptive icons
THE INVESTIGATION
Collected the real submission constraints teams hit: multi-size exports, 5-up store sets, icon matrices, and ZIP packaging without a backend.
THE STRATEGY
Ship a Next.js local canvas pipeline: upload frames once, apply templates and copy, export compliant PNGs and icon packs as ZIP — never leave the device.
WHAT I BUILT
- •Screenshot studio with templates and multi-device specs
- •App icon packager for Xcode and Android Studio
- •Client-side ZIP export, no server image upload
- •App Store + Google Play oriented workflows
THE HARD PART
Matching store-accurate sizes and packaging formats while remaining fully offline in the browser.
THE VERDICT
- •Public free tool at ios-app-icon-util.vercel.app
- •Local-only processing with no account required
- •Covers screenshots and full icon resource packs
