I have the premium version. Today the app pushed a "consent to use your personal data" for more reasons than I can list here. It wants to share with 143 TCF vendors and 78 ad partners, and this is without the "legitimate interest" nonsense that adds even more. Given the nature of this app, which can store passwords to network shares, it's just demolished all trust I had in it. It's one thing to be advert / data mined for free users, but paying users shouldn't have even had this prompt.

I've used this as part of a backup solution for a while and feel I can rely on it. One feature it would be nice to have would be to trigger one sync when another one finishes. I have multiple jobs using the same server and currently just leave along time window for the first one to finish, but that means the disks spin-down unnecessarily in between each one.

This is a pretty good app. It allows you to automatically backup/transfer any folder (& the files/subfldrs in it) on your phone to an SD card, your own Dropbox or other cloud acct (& v.v.) with a lot of customiz'n options, even in the free vers. Some ads but NOT annoying. The ONLY PROBLEM I've found is that even with scheduling turned OFF, it keeps starting up automatically at inopportune times, which IS ANNOYING. I haven't found the setting to prevent this. Hence 4☆ not 5☆. A fix gets ☆☆☆☆☆.
