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.

Design your complete App Store screenshot set in one app - natively on iPhone, iPad, and Mac, not in a browser tab. Then push the same set out as a video to every marketing channel, without rebuilding a thing. App Screenshot is a visual editor for your App Store presence. Captures, text, mockups, backgrounds, shapes, and effects all live in one project. No jumping between three design tools, no rebuilding everything for each device size. Design your screenshots: - Complete sets in one app, text, images, and layouts stay editable at any point - Drop screenshots into Apple device mockups, then rotate, scale, and arrange them freely - Keep one consistent look across every screen with Themes and Presets - Reach for a modern style with Liquid Glass, Bento layouts, and the Pattern Creator - Line everything up precisely with grids and snapping Turn that set into a video: - Export the same design as a video for social media, product pages, and presentations - Reuse the screens you already made instead of designing again for each channel - One consistent look across screenshots and videos Localization that keeps up: - Manage text centrally through String Catalogs and link it to your screens - Switch between languages instantly to catch line breaks, layout shifts, and translations that run too long - Assign market-specific images and media - Export every language you've set up in one pass One project, all your devices: - Synced across iPhone, iPad, and Mac with CloudKit, start on your phone, finish on your Mac - No files to shuffle back and forth From draft to the Store: - Export finished sets in the right App Store sizes - Send them straight to App Store Connect and match them to the correct languages and devices (optional, manual upload still works) Plus unlimited projects and screens, project folders, a central media library, screen versions for A/B variants, groups, and more. App Screenshot is built for developers who want to own their store presence and not start from scratch every release. Download the app and design your screenshots and videos in one place.

Verdict
The clearest difference is update cadence: OnDevice at every 3 days against App Screenshot's every 2 months. OnDevice also leads on monetization model (free vs free with in-app purchases). App Screenshot's advantage is device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.
