Everything you need to publish an app

Getting an app into the App Store and Google Play means producing a surprising number of assets: launcher icons in a dozen sizes, store screenshots in exact dimensions, launch screens, a hosted privacy policy, a favicon for your landing page and a QR code for your marketing. AppNimbus puts all of those small jobs in one place.

A typical launch checklist

  1. Create your app icons for Xcode and Android Studio from one 1024×1024 image.
  2. Make launch / splash screens that match your icon.
  3. Design store screenshots with captions in the sizes Apple and Google require.
  4. Generate a privacy policy and paste its link into App Store Connect and Play Console.
  5. Add a favicon and a download QR code to your landing page.

Private by design

Unlike many online converters, AppNimbus never uploads your files. Every tool runs locally in your browser, so unreleased app designs and screenshots stay on your device.
