Möbius Sync is a free app available for iPhone and iPad that brings the power of Syncthing to iOS devices. With Möbius Sync, you can easily synchronize selected files between your iOS devices and other devices supported by Syncthing, all without the need for any cloud service.

One of the standout features of Möbius Sync is its support for multiple folders and multiple remote devices. You can create synchronized folders either within the Möbius Sync sandbox or by accessing other apps' sandboxes (a paid feature). However, it's important to note that accessing other apps' sandboxes is an experimental feature that may affect the functionality of those apps.

Möbius Sync utilizes the open-source Syncthing engine internally, ensuring reliable and secure file synchronization. The app offers free usage within the Möbius Sync sandbox for files up to 20MB. For unlimited file syncing, including files in other apps' sandboxes, you can make a one-time purchase.

Whether you need to sync important documents, photos, or other files across your devices, Möbius Sync provides a seamless and convenient solution. With its user-friendly interface and powerful features, Möbius Sync is a must-have app for anyone seeking efficient file synchronization on their iOS devices.
