NextSync - A Syncthing front-end for Android and Windows

This is a vibe-coded project, built entirely with AI assistance. I handled the design and UX myself, while the logic was AI-generated and refined through iterative prompting. Use it or fork it.

Credits to: Syncthing.

You have to download the Syncthing core from their latest release. I'm currently using v2.1.5.

I built this for myself only, so I have only used it on my two devices and do not know how it behaves on others. That is why I am sharing the source, so that if something goes wrong, you can open an agent in the codebase and troubleshoot for your own setup.

Warning

This is a very early release and some things might be unstable. Please be careful when using this app. Use at your own risk.
