Your files. Your server. Your ownCloud. Connect to your ownCloud Infinite Scale (oCIS) or ownCloud Classic server and access your private cloud from anywhere. Open source, self-hosted, no third-party cloud required. ownCloud gives you full control over your data. Whether you're a teacher accessing the school cloud, a sysadmin managing a federated deployment, or someone who simply refuses to hand their files to a big-tech provider — this app is built for you. FEATURES - Browse, Edit and Create files Work with your files directly on your device with Files integration, built-in markup tools*, and the document scanner*. Switch between list view and three grid views — all updating live as changes happen locally or remotely. - Built-in viewers View common file types right in the app. Swipe through images in carousel view. Navigate PDFs using their table of contents or full-text search. - Spaces (oCIS) On ownCloud Infinite Scale servers, organise work into Spaces with dedicated permissions, members, and quotas. Full Spaces support is built in. - Sharing and Collaboration Share files and folders with other users on the same server or externally via public links. Fine-grained permissions, password protection, and expiry dates give you control over every share. - Search (Local and Remote) Filter by date, size, type, or location. Save searches and create reusable templates. Local search works fully offline. On oCIS servers, server-side search can also find content inside files (depending on server configuration). - Offline Support Mark files and folders for offline availability. Work without a connection. Changes sync automatically when you're back online. Built from the ground up with offline-first in mind. - Multiple Accounts Connect to several ownCloud servers and accounts simultaneously. Switch between them seamlessly. - Deep OS Integration Native iPadOS multitasking, drag and drop, File Provider, and Shortcuts support. Built by developers who care about how apps should feel on Apple platforms. - Security The app tracks your server's TLS certificates and warns you about unexpected changes. Review certificate details (including a diff of what changed) and accept or reject — right from the app. * Some features may require an In-App Purchase or Subscription. SYSTEM REQUIREMENTS iOS 15.4 or later, iPadOS 15.4 or later ABOUT OWNCLOUD ownCloud is the original open source platform for self-hosted file sync, share, and collaboration.

With Synctrain you can securely synchronize files with other devices that have Syncthing installed. You can choose to synchronize full folders, or choose specific files. With Synctrain you can also stream audio and video files from other devices. When you synchronize files, all changes, including deleting files, also happen on your other devices. Do not use Synctrain for back-up purposes, and always keep a back-up of your data. You decide with which devices you share which files. This also means the app makers cannot help you access or recover any lost files. This app is powered by Syncthing. This app is however not associated with or endorsed by Syncthing nor its developers. Please do not expect support from the Syncthing developers. Instead, contact the maker of this app if you have questions.
