I was using this but when I switched to iOS I switched to Bitwarden.

What are you using for Syncthing on Android? There used to be an official Syncthing app for Android but then they stopped maintaining it. There was a popular fork but then that person stopped as well.

I looked into using Syncthing on iOS but there was only Möbius Sync and it didn’t run in the background. This is was made me finally switch to Bitwarden. But of course now I need figure what to do next.

I have had an excellent experience with Sushitrain/Synctrain on iOS [0]. It’s honestly the nicest Syncthing client I’ve used, although to be fair desktop-oriented clients have different design goals than mobile clientsm

I use syncthing-fork from fdroid, works great
