This app is garbage. It does not have the feature to see if files are in fact synced. Sure, it has options to check file size, or sumcheck and has a feature to use a temp file, but it's too stupid to do that except on the initial try. If syncing is interrupted it will never look again. No program can claim to 'sync' files if it doesn't check to see if they are synced. Duh! Too bad because otherwise it seems pretty decent. But if it can't do it's number 1 responsibility, it is useless.

Redundant garbage app. It sold itself as an app that could backup files between Google Drive and other cloud storage platforms. However it would crash on any file transfer of over 100 would not completely download all files. It charges for something that you can actually do yourself with your platform's cloud storage. I requested a refund and gave this poor rating because it was such a frustrating waste of time.

Your app needs to learn to stop being so hard on itself. I get notifications all the time that it failed to sync, but after it successfully synced everything. I'm not kidding, over and over I always get notifications saying sync failed, but everything syncs! It needs to learn to like itself and accept that it's very good at what it does. I fully understand low self esteem and being self critical, but honestly, this app works, and very very well. I just feel it doesn't give itself enough credit.
