App Store Tools
8 free toolsIcons, screenshots, store graphics, privacy policies, and submission checklists for iOS and Android.
App Store tools cover the part of shipping an app that is not code: every icon size from one image, App Store screenshots and iOS 27 header art, the Google Play feature graphic, a privacy policy both stores accept, and step-by-step checklists for getting through App Store review and Google Play's production access. Each checklist step links to the tool that produces what that step asks for, and the specs are dated so you know when they were last checked.
Everything here runs in your browser: files and text are processed locally and never uploaded. Checklist progress and policy drafts are saved only in your browser's local storage.
