Create App Store screenshots that are ready to launch. Launch Canvas helps iOS developers turn real app screens into polished App Store screenshots without using a complex design tool. Paste your App Store link to start faster. Launch Canvas can use public listing details such as your app name, current version, icon and public screenshots where available, then help you build a premium screenshot set from your real app screens. Import screenshots from Photos or Files, choose a launch-ready layout, add clear marketing copy, apply an iPhone frame, and export exact-size PNG images for App Store submission. Built for App Store screenshot creation: • Start from an App Store link where public data is available • Import real screenshots from Photos or Files • Create the first 3 screenshots as a launch hero set • Preview screenshots together like an App Store listing • Add titles, subtitles and supporting copy per screen • Use iPhone frames, colour palettes and launch-ready styles • Fine-tune text, colour, layout and device presentation • Export production-ready PNGs at exact App Store dimensions Launch Canvas is focused on App Store screenshots, not generic graphic design. It is also not an AI image generator. There are no prompts, random outputs or invented app screens. You work from your real screenshots and get deterministic, submission-ready images. Use Launch Canvas for: • New app launches • Screenshot refreshes • Version updates • ASO experiments • Product page improvements • Cleaner app marketing visuals No account is required. No server is used for editing. Your screenshots stay local to your device. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

OnDevice is a local-first AI studio for iPhone. Run compatible language, vision, speech, and image models on your device. Browse models and choose what to download. Model size, memory use, and speed depend on your hardware. CHAT AND CREATE Ask questions, write, work with code, save snippets, and export conversations. Use camera or photo input with a compatible vision model, or use built-in OCR without downloading a vision model. Voice conversations use local Apple speech by default, with optional downloadable neural voices. Compatible image models support local image generation, which can be restricted with a parental PIN. YOU CHOOSE THE CONNECTIONS Local inference uses installed models. Network features are optional: model discovery and downloads, web search, paired Mac tools, a local API, and iCloud sync. Web providers may receive the queries or content you choose to send and may require their own API account. No app account is required for local use; there is no analytics SDK. REQUIREMENTS Requires iOS 18 or later. Downloadable models need storage and sufficient available memory. The app may pause or refuse heavy workloads when the device is too hot or memory is low. Model compatibility and performance vary by device.
