Can you help out here. I have struggles from day 1 with local music on the iPhone. Its the last thing I cannot seem to overcome. I have a folder on my Synology NAS called music. I chuck files in there I like and try to sync it to my iPhone. DS Audio – is an ok APP but it doesn’t sync reliably, some times it takes 24 hours for changes to be main on my iPhone. Apple Music, using the 2 local Apple Apps on my PC. Apple Devices and Apple Music. it does a bad job of Syncing as well. some songs never turn up and I have to plug my phone into my PC. Using Synology Drive or Syncthing, I can sync a folder from either my Unraid NAS or Synology NAS but I can’t find an app that will play local music, everything thinks you want to play music from the cloud.. I am open to a new APP, a new Syncing service & anything… I have overcome a few issues to get here.. and I think I will keep the iPhone moving forward if I can overcome this one.. No pressure.
Based on your challenges with syncing local music from your Synology NAS to your iPhone, here’s a tailored solution combining reliable sync methods and playback apps, leveraging your existing setup:

Start with Evermusic + QuickConnect for simplicity. If sync delays persist, switch to Syncthing + VLC. This workflow eliminates cloud dependency and leverages your NAS directly for true offline playback.
