What users are saying

1. Great app with a lot of features and options! I currently use it to backup my camera roll on a schedule from my phone to a USB drive connected to my router, and it works like a charm! However, I recently bought a new phone and started to mess with Protect Battery.

2. You can simply hit sync again to continue the sync, but if you have a large number of files, it gets old fast.Works great but can you add one more feature, a thermal throttle.

3. I loathe having to babysit the phone, manually starting and stopping the sync job as temperature rises.

4. When running a sync job my phone will get ridiculously hot to the point where the device will shut down due to the high temperature.

5. This is a good alternative to Google Backup if you have a proper SMB share setup to sync with.

6. (e.g. when im sleeping) When I wake up it always says there was a sync error and that it could not connect to wifi.

7. I have a sync set up every night while charging and connected to wifi.

8. Was fairly easy to set up a sync job from my NAS to my phone.

9. Unfortunately, the app will stop syncing after a random number of files and throw error "failed to acquire credits in time" after halfway moving a file, then stop syncing.

10. As a side note, the developer is very responsive for support, if there were a separate category for this, he'd rate 5 stars.Overall, this would have been an amazing app, easy to use and customize, and fulfills an important role.

11. It does exactly what I need, which is sync master copies from my internal.
