### 1/5 — No longer works

*2026-08-24, version 5.1.4*

I have used this App for many years without any issues, until it stopped working with an App Store validation error on my M-series Mac. Support has been patchy and ineffective. None of the usual delete/restore/reboot has been effective. I have moved to native NAS tools from Synology which work brilliantly.

### 5/5 — Useful App

*2026-08-24, version 5.1.4*

Really useful app for backing up my SSD onto my HDD as well. I use Time Machine to back up my laptop, but then all my content on my SSD gets mirrored onto an HDD with this app, so it's been very helpful.

### 1/5 — Always Buggy

*2026-08-07, version 5.1.3*

I gave up when it could not backup folders with a huge number of files.

### 4/5 — フォルダ間の同期に使用した

*2026-07-24*

フォルダ間の同期は特に問題なくできました。日本語ユーザーなので日本語のマニュアルが整備されればもっと安心して使えます

### 5/5 — Simply works

*2026-07-22, version 5.1.3*

Numerous options that work flawlessly.  Clear instructions and easy to set up.  Spend some time with it and you can do amazing things.

### 5/5 — Simply fast

*2026-07-22, version 5.1.3*

I have been using Sync Folders Pro for >10 years, perhaps longer, running on different machines and operating systems (Mac). I am a photographer and have many large files produced each week so need to have a robust way of backup to multiple disks. Some of the files are huge. I also backup my documents. The system is automated and very fast.

### 5/5 — Powerful yet easy to use

*2026-06-27, version 5.1.1*

Makes keeping back up folders on multiple drives very easy and most importantly, performs reliably, giving me confidence that I will no lose any work if a drive fails — as has happened more than once!

### 5/5 — Peace of mind

*2026-06-17, version 1.2*

I have used the app for many years. Despite having most of my data in iCloud, I like yo know it is also synchronised with my local NAS.  Easy to use , set up and reliable.

### 5/5 — Love the clear sync modes when syncing !

*2026-06-17, version 5.1.1*

Several times while syncing with other software I have had files overwritten or deleted when this was not my intention. I just love the A to B options with SYNC FOLDERS PRO, clearly showing what is going to happen in the small table that pops up. This permits a sync that is tailored to any need and prevents costly mistakes while syncing. Love it !

### 5/5 — Game Changer

*2026-06-17, version 5.1.1*

The golden rule for working digitally is to create a backup of the files you are working on. But when do you actually do this? If you are like me and just forget, then this is the app for you. It is utterly brilliant and has saved me on more times than I care to remember. I have a folder on my desktop with all of my files in. This is backed up by Sync Folders Pro to an external drive I carry with me, which automatically backs up all the work I do in that folder. As soon as I am plugged into my home network, it auto-copies to a larger home NAS drive (or another external drive), so I now have 3 folders where the work sits. I will only ever go to the external drive if I get a corruption or delete a file by mistake. It is genius and for the money, a complete no-brainer.
