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.

About

Read full description

OnBoard is a personal intelligent space that runs completely locally on your device. Powered by Google's Gemma 4 language model and LiteRT-LM technology, the app delivers instant responses without relying on third-party servers, cloud computing, or subscriptions. Everything you write, record, or upload stays exclusively on your iPhone. MAIN FEATURES: • Local Text Chat: A fully featured intelligent assistant that speaks and thinks offline. • Image Analysis: Upload photos from your gallery or take pictures with your camera — the AI will help identify objects, read text, or analyze details. • Voice Notes and Queries: Local transcription converts your voice into text and instantly passes it to the model for analysis. • Flexible Settings: Control the "creativity" of responses by adjusting Temperature, Top-P, Top-K, and manage the context window size. OPTIONAL WEB SEARCH: Need current news, exchange rates, or the weather? Simply connect your own search service API key in the settings. SECURITY AND PRIVACY: The app does not collect, store, or share your conversations. The model is integrated directly into the app and utilizes the power of your iPhone's GPU. Your thoughts, ideas, and diary entries belong to you alone.
