Codable is a lightweight web developer toolkit for iPhone and iPad. Use the Safari extension to inspect pages where they already run. Select elements inline, browse the DOM tree, view HTML, inspect styles and node metadata, evaluate JavaScript, capture console output, view source, inspect resources, and review network activity. On supported devices, on-device Apple Intelligence can be used to find elements and perform edits. The main app has three tabs for development and testing: - Resize: a browser surface for testing responsive layouts with custom viewport width, height, scale, presets, and drag handles. - Scratchpad: a JavaScript editor and runner with syntax coloring, code-focused keyboard shortcuts, document support, and optional Apple Intelligence assistance on supported devices. - Extension: a small info page with instructions on how to enable the Safari extension, and a way to view a local demo page with CSS, JavaScript, resources, console logs, and network requests to try out the tools within Safari.

SyncUp is an open-source client for the Syncthing protocol. A peer-to-peer file synchronization protocol that has been around since 2014. If you already run a Syncthing node on your computer, NAS, or home server, SyncUp lets your iPhone join the same network of devices and keep selected folders in sync. All transfers happen directly between devices you own, end-to-end encrypted with TLS 1.3. This app does not host or store your files on any third-party server. It connects only to peers you have explicitly authorized. FEATURES • QR code device pairing -> scan a peer's code or display your own. The 56-character device ID never has to be typed by hand. • Folder sharing controls -> accept, ignore, or auto-accept folder offers from peers you trust. • Live status -> folder progress, peer connection state, and incoming offers update in near real time. • Per-folder pause and resume from Settings. HOW SYNC WORKS ON IOS iOS reserves continuous background execution for a small set of app categories that SyncUp does not belong to. Sync runs in the foreground whenever the app is open, and SyncUp also registers two background tasks that the system schedules opportunistically, typically a short window or two per day, with the exact timing controlled by iOS. For an always-online node, run a Syncthing instance on a computer or home server that stays powered on. Your iPhone reconciles against it whenever it next runs. OPEN SOURCE SyncUp is licensed under MPL-2.0. The Syncthing daemon is embedded in-process and the full source code is available on GitHub. REQUIREMENTS You will need at least one other device running Syncthing (on macOS, Windows, Linux, Android, or another iOS device with this app) for SyncUp to be useful. Visit syncthing.net to learn more about the protocol.
