I generally agree with the other reviews that you need to be able to try this without paying. I didn't get off the starting blocks with this app as it asked for payment to add a local drive on my phone, and that's just setting up the origin folder without even adding the destination. That's a pity as I won't be trying this out and it looked like it had the features i might be looking for.

Looks like an interesting program but you have to pay $4 just to see if it does what you want. At this point, you have so much of it behind a paywall, I can't tell if it does what I need. My advice would be to have the program allow you to set up a local sync and tell you what it would do, but no actually do it without the payment.

Backup copies EVERYTHING, overwriting existing backup. Copying files is s-l-o-w. File dates and times are not preserved, all files are set to current date and time in both source and destination. Copying via default file explorer/manager is faster.
