### 5/5 — Super!

*2026-03-19*

Man braucht ein paar Minuten um die Funktionen und unterschiedlichen Ansichten zu verstehen - aber dann ist es ein mächtiges Tool :-) Vielen Dank!

### 5/5 — Schnell und Zuverlässig

*2026-02-12*

Einfach zu bedienen. Sync von 1,5 TB war in wenigen Stunden erledigt. Top! Allerdings kann man die „Aufgaben“ nicht speichern. Fair enough bei einer Free-Version. Da ich mehrere Aufgaben habe und nicht jedes Mal alles neu einstellen möchte, habe ich nach dem Text die Pro-Version gekauft. Einmalig 10€ kann man nicht meckern. Top Preis für eine gute App.

### 3/5 — Not working properly in macOS Tahoe 26.2

*2026-02-06*

Sync Folders used to function effectively after the initial setup in earlier versions of macOS. However, in macOS Tahoe 26.2, we encounter persistent failures, even though the profiles previously worked seamlessly. For instance, we frequently encounter issues reading files in ~/Library, despite providing it with full disk access multiple times. Consequently, I’ve switched to Syncovery (which also has its own learning curve), but it has eliminated all read errors.

### 5/5 — So useful

*2026-01-02, version 1.2*

It’s a lifesaver for backups because it only copies the files that have actually changed which saves me so much time when moving stuff between my device and external drives.

### 1/5 — !!! ACHTUNG !!!

*2025-12-30*

Ich meide diese App aufgrund der geopolitischen Lage.
In der offiziellen Privacy Policy steht ausdrücklich, dass personenbezogene Daten in die Russische Föderation übertragen und dort verarbeitet werden können!!!

Der Entwickler namens Vadim Zybin kommt aus Russland. Allerdings gibt es auf der offiziellen Website von GreenWorldSoft keine spezifischen Informationen zur Unternehmensadresse!

### 4/5 — It works

*2025-10-28, version 1.2*

I use this app to back up my drone photos and videos to my phone (iPhone 17 pro max, 1TB) then to my 2TB Lexar Professional Go SSD card.  It actually works.  I just wish it explains usage in more detail.

### 2/5 — Syncing does not work

*2025-07-11*

… for a smb: folder on MacOS. It found the same files twice and takes a lot of valuable time.
 Hands off!!!

### 4/5 — Schnelle und zuverlässige Synchronisation

*2025-07-02*

Habe vor einigen Monaten zwei Ordner mit einander verlinkt und sync gestartet, seit dem keine Probleme gehabt. Die App macht was sie soll.

### 1/5 — Confusing, difficult to configure

*2025-05-01, version 4.7.6*

Almost impossible to determine what it’s going to do and the CONSTANT opening of a browser and the App Store to get you to buy Pro (Which I may have done) are just too annoying to deal with.  Deleted.

### 3/5 — Seit dem letzten Update Absturz

*2025-02-21*

Tolles Tool, seit dem letzten Update stürzt es aber ab.
