In their own words

What people are saying about DeltaSync.

Notes from the r/macapps launch thread.

So I tested your tool with syncing the files to pCloud. It works well. I did a 300GB sync folder by folder, and also synced two HDDs.
Showing the comparison before sync is the right product boundary, especially for family backup workflows.
Thank you. Needed something this simple. Thank you so much.
OMG I love this
Nice simple little Rsync app there.
Awesome project!
