## What is Resilio Sync?

Sync is the best way to transfer files between your Mac, PC, NAS, and even server. 

Create your own private cloud. Connect devices and sync files securely without sending them on third-party servers. We don’t limit your speed or storage space: our technology works especially well with huge files. 

No storage limits
• Sync as much data as you have on your hard drives.

Automatic camera backup
• Sync will back up photos and videos as soon as you take them.
• You can then delete photos from your phone and save space.  

Direct transfers, no cloud
• Your information is never stored on servers in the cloud, so nobody can access it without your permission. 
• Transfer files directly and fast using peer-to-peer technology (p2p).

Any device and platform
• Access folders and upload files to your tablet, PC, Mac, NAS, and even server.

Supports all file types
• Add photos, videos, music, docs, and PDFs from other apps to any of your synced folders.

Save space
• Selective Sync lets you save only the files you need.

To get the best performance and to avoid running up your data charges while syncing folders, we recommend leaving the "Use Cellular Data" setting off.

### 5/5 — iCloud Alternative

*2026-07-18, version 3.1.2*

Once you get the hang of Resilio it is easy to use. You are able to back up photos and videos without having to pay for icloud. Resilio is also great for transferring photos and videos from Apple to android without loosing picture quality.

### 2/5 — Needs some critical features

*2026-05-31, version 3.1.2*

App seems to work well but you have to select each individual file or photo individually. What kind of design choice is this?! I’m synchronizing tens of thousands of photos from a few select photo albums on my phone. Why can’t I select the album? Or why can’t I drag and select ranges of pictures? Instead I have to pick each photo individually and that takes FOREVER! I finally gave up after selecting 2,000 photos and decided to try a different app that does allow me to sync an album. I can’t see using this app without the ability to add albums. Hoping this will be fixed in the future because I want to use this app, it has promising features, but right now it’s too slow and too inefficient to use with tens of thousands of files.

Please add ability to select a photo album and include updating changed pictures that have been added or removed from the selected album. I’m sure that I’m not the only person who has faced this issue.

### 3/5 — Something broke

*2026-05-16, version 3.1.2*

I used to have no problems with the app, but now the connection between my Linux laptop and iPhone keeps dropping after just a second. I’ve tried everything I can think of including direct connection and nothing works.

### 3/5 — So close to amazing

*2026-01-01, version 3.1.2*

This app seems to backup photos fine. It also allows me to upload or download a file or two without issue. However, there are a number of problems. I think the most important one is the Files app integration just seems plain broken. I can see a few of my folders, but most are missing along with all my files. Second, the capabilities and user interface of the app feel incomplete. Finally, I think the terminology should be cleaned up to make things more clear. For example, the word “remove” is used to mean “delete the local copy of this file and replace it with the placeholder”, as well as “delete all copies of this file across all devices”, depending on context.

### 3/5 — Needs some critical features

*2025-12-26, version 3.1.2*

App seems to work well but you have to select each individual file or photo individually. What kind of design choice is this?! I’m synchronizing tens of thousands of photos from a few select photo albums on my phone. Why can’t I select the album? Or why can’t I drag and multi-select ranges of pictures at one time? Instead I have to pick each photo individually and that takes FOREVER! I finally gave up after selecting 2,000 photos and figured I’ll go a different route. I thought this would be the answer for me but I can’t see using this while operating this way and picking each photo individually, it’s just too inefficient. Hoping this will be fixed in the future because I could see using this app but I’m sure that I’m not the only person who has faced this issue.

### 5/5 — Great app

*2025-11-25, version 3.1.2*

I love this app it makes the whole process of moving files very simple, but can I ask you actually have a proper raspberry pi repository? I would like to install it easier and not have the package break because it’s trying to update on its own.

### 4/5 — Very good for all platforms files transfer

*2025-11-11, version 3.1.1*

Awesome app! 1 downside for me though is that the search function are not good, like I’m trying to find something that contains the word “cat” in it, but all I see are a ton of title that have no “cat” in it, but contains all the letters “c” “a” “t”  (not even in order of “cat”)instead please fix it!

### 5/5 — Really great app for syncing files

*2025-11-09, version 3.1.1*

Amazing free app to sync files directly between mobile & desktop devices!

### 1/5 — Mobile app iPad OS can't sync with each other

*2025-10-29, version 3.1.0*

Mobile app on iOS can't sync with desktop, but desktop can sync with nas. Mobile app iPad OS can't sync with each other

### 5/5 — great app

*2025-09-27, version 3.1.0*

fast and customizable
