It does a great job of syncing with multiple cloud storage services, allowing reasonable syncing defaults, and force syncing for special occasions. This app is definitely worth a contribution, but having both a "premium" in-app upgrade and a separate "pro" version is just stupid and asking for user frustration. It is especially bad because these two paid versions have the same features.

Does what I need - sync on demand with the exact folding pairings I want/need - on my phone for interacting with pCloud. The official app doesn't do this on mobile, and the other two apps I tried were SLOw. This is as fast as using Onesync with OneDrive, but the general version of that app is slow - 4 hours for a download-less/upload-less vs 30-40m!!! Two folders I sync are large and complex so if I sync everything its going to take a little time, but 4 hours is crazy!

I'm so glad I found this app, it makes automated backups and folder syncing (similar to apps like OneDrive) to a local server so incredibly easy. I think my only complaint is the error messages can be a bit confusing or hard to access/find in the app itself. I had an older phone that didn't like to sync and I couldn't for the life of me figure out why. The automated backup/syncing is also not EXACTLY at the time you specify, it can vary some. This isn't a problem in my use case though.
