I have been waiting for a native syncthing client fry iOS since using it as my primary desktop sync tool three years ago. This app works great and while there is some chunkiness to using it iPhone, it’s much better to retain the privacy and security nature of the platform.

Developer is fantastic and quickly remedy to bug her reported a week ago.

Missing a key feature for mobile

This is a pretty solid GUI for Syncthing. I’m still experimenting, but there is one key feature that appears to be missing — *especially* important for mobile devices.

I need the ability to selectively sync. I want to see a listing of everything that’s in a given shared directory, but don’t actually download it to my phone unless I say so.

This is available in Resilio Sync, which is the main app I’m considering other than Syncthing. In Resilio I have a synced folder on my home computer that has almost a Terabyte of stuff. On my phone I can browse all of it, and if I want a particular file I tap to download that file to my phone.

Unless I’m missing a setting somewhere, Mobius and Syncthing doesn’t have anything like this. I either download it to my phone or it’s not linked at all. No in between.
